+Exim is a mail transfer agent (MTA) used on Unix-like operating systems. 
+It is freely available under the GNU GPL and it aims to be a general 
+and flexible mailer with extensive facilities for checking incoming e-mail.
+
+Exim was orginally written by Philip Hazel for use in the University 
+of Cambridge Computing Services e-mail systems. 
+
+Before you can build Exim, you have to create an "exim" user and group:
+      #	groupadd -g 222 exim
+      #	useradd -d /var/spool/exim -g exim -s /bin/false -u 222 exim
+The recommended uid/gid is 222, but others are fine if you prefer - 
+see http://slackbuilds.org/uid_gid.txt for other recommendations.
+
+There's no "configure" script; instead Exim is configured by editing a well
+documented Makefile, which is then included during the build process.  The
+provided "exim.Makefile" will build an all-purpose Exim daemon with almost
+all of the features that will work on a standard Slackware system.
+
+Exim can be integrated with other email tools such as Clamav, Spamassassin,
+Bogofilter, and others available at Slackbuilds.org.  You might also be
+interested in the "exim-html" package, an extensive documentation for Exim.
+
+WARNING: this package is intended as a drop-in replacement for Sendmail.
+As a result, there are some inevitable filename conflicts between Sendmail
+and Exim.  REMOVE SENDMAIL BEFORE INSTALLING THIS PACKAGE!

+##################################################
+#          The Exim mail transport agent         #
+##################################################
+
+# This is the template for Exim's main build-time configuration file. It
+# contains settings that are independent of any operating system. These are
+# things that are mostly sysadmin choices. The items below are divided into
+# those you must specify, those you probably want to specify, those you might
+# often want to specify, and those that you almost never need to mention.
+
+# Edit this file and save the result to a file called Local/Makefile within the
+# Exim distribution directory before running the "make" command.
+
+# Things that depend on the operating system have default settings in
+# OS/Makefile-Default, but these are overridden for some OS by files called
+# called OS/Makefile-<osname>. You can further override these by creating files
+# called Local/Makefile-<osname>, where "<osname>" stands for the name of your
+# operating system - look at the names in the OS directory to see which names
+# are recognized.
+
+# However, if you are building Exim for a single OS only, you don't need to
+# worry about setting up Local/Makefile-<osname>. Any build-time configuration
+# settings you require can in fact be placed in the one file called
+# Local/Makefile. It is only if you are building for several OS from the same
+# source files that you need to worry about splitting off your own OS-dependent
+# settings into separate files. (There's more explanation about how this all
+# works in the toplevel README file, under "Modifying the building process", as
+# well as in the Exim specification.)
+
+# One OS-specific thing that may need to be changed is the command for running
+# the C compiler; the overall default is gcc, but some OS Makefiles specify cc.
+# You can override anything that is set by putting CC=whatever in your
+# Local/Makefile.
+
+# NOTE: You should never need to edit any of the distributed Makefiles; all
+# overriding can be done in your Local/Makefile(s). This will make it easier
+# for you when the next release comes along.
+
+# The location of the X11 libraries is something else that is quite variable
+# even between different versions of the same operating system (and indeed
+# there are different versions of X11 as well, of course). The four settings
+# concerned here are X11, XINCLUDE, XLFLAGS (linking flags) and X11_LD_LIB
+# (dynamic run-time library). You need not worry about X11 unless you want to
+# compile the Exim monitor utility. Exim itself does not use X11.
+
+# Another area of variability between systems is the type and location of the
+# DBM library package. Exim has support for ndbm, gdbm, tdb, and Berkeley DB.
+# By default the code assumes ndbm; this often works with gdbm or DB, provided
+# they are correctly installed, via their compatibility interfaces. However,
+# Exim can also be configured to use the native calls for Berkeley DB (obsolete
+# versions 1.85, 2.x, 3.x, or the current 4.x version) and also for gdbm.
+
+# For some operating systems, a default DBM library (other than ndbm) is
+# selected by a setting in the OS-specific Makefile. Most modern OS now have
+# a DBM library installed as standard, and in many cases this will be selected
+# for you by the OS-specific configuration. If Exim compiles without any
+# problems, you probably do not have to worry about the DBM library. If you
+# do want or need to change it, you should first read the discussion in the
+# file doc/dbm.discuss.txt, which also contains instructions for testing Exim's
+# interface to the DBM library.
+
+# In Local/Makefiles blank lines and lines starting with # are ignored. It is
+# also permitted to use the # character to add a comment to a setting, for
+# example
+#
+# EXIM_GID=42   # the "mail" group
+#
+# However, with some versions of "make" this works only if there is no white
+# space between the end of the setting and the #, so perhaps it is best
+# avoided. A consequence of this facility is that it is not possible to have
+# the # character present in any setting, but I can't think of any cases where
+# this would be wanted.

+
+# Exim will not build unless you specify BIN_DIRECTORY, CONFIGURE_FILE, and
+# EXIM_USER. You also need EXIM_GROUP if EXIM_USER specifies a uid by number.
+
+# If you don't specify SPOOL_DIRECTORY, Exim won't fail to build. However, it
+# really is a very good idea to specify it here rather than at run time. This
+# is particularly true if you let the logs go to their default location in the
+# spool directory, because it means that the location of the logs is known
+# before Exim has read the run time configuration file.
+
+#------------------------------------------------------------------------------
+# BIN_DIRECTORY defines where the exim binary will be installed by "make
+# install". The path is also used internally by Exim when it needs to re-invoke
+# itself, either to send an error message, or to recover root privilege. Exim's
+# utility binaries and scripts are also installed in this directory. There is
+# no "standard" place for the binary directory. Some people like to keep all
+# the Exim files under one directory such as /usr/exim; others just let the
+# Exim binaries go into an existing directory such as /usr/sbin or
+# /usr/local/sbin. The installation script will try to create this directory,
+# and any superior directories, if they do not exist.
+
+BIN_DIRECTORY=/usr/sbin
+
+
+#------------------------------------------------------------------------------
+# CONFIGURE_FILE defines where Exim's run time configuration file is to be
+# found. It is the complete pathname for the file, not just a directory. The
+# location of all other run time files and directories can be changed in the
+# run time configuration file. There is a lot of variety in the choice of
+# location in different OS, and in the preferences of different sysadmins. Some
+# common locations are in /etc or /etc/mail or /usr/local/etc or
+# /usr/local/etc/mail. Another possibility is to keep all the Exim files under
+# a single directory such as /usr/exim. Whatever you choose, the installation
+# script will try to make the directory and any superior directories if they
+# don't exist. It will also install a default runtime configuration if this
+# file does not exist.
+
+CONFIGURE_FILE=/etc/exim/exim.conf
+
+# It is possible to specify a colon-separated list of files for CONFIGURE_FILE.
+# In this case, Exim will use the first of them that exists when it is run.
+# However, if a list is specified, the installation script no longer tries to
+# make superior directories or to install a default runtime configuration.
+
+
+#------------------------------------------------------------------------------
+# The Exim binary must normally be setuid root, so that it starts executing as
+# root, but (depending on the options with which it is called) it does not
+# always need to retain the root privilege. These settings define the user and
+# group that is used for Exim processes when they no longer need to be root. In
+# particular, this applies when receiving messages and when doing remote
+# deliveries. (Local deliveries run as various non-root users, typically as the
+# owner of a local mailbox.) Specifying these values as root is very strongly
+# discouraged.
+
+EXIM_USER=exim
+
+# If you specify EXIM_USER as a name, this is looked up at build time, and the
+# uid number is built into the binary. However, you can specify that this
+# lookup is deferred until runtime. In this case, it is the name that is built
+# into the binary. You can do this by a setting of the form:
+
+# EXIM_USER=ref:exim
+
+# In other words, put "ref:" in front of the user name. If you set EXIM_USER
+# like this, any value specified for EXIM_GROUP is also passed "by reference".
+# Although this costs a bit of resource at runtime, it is convenient to use
+# this feature when building binaries that are to be run on multiple systems
+# where the name may refer to different uids. It also allows you to build Exim
+# on a system where there is no Exim user defined.
+
+# If the setting of EXIM_USER is numeric (e.g. EXIM_USER=42), there must
+# also be a setting of EXIM_GROUP. If, on the other hand, you use a name
+# for EXIM_USER (e.g. EXIM_USER=exim), you don't need to set EXIM_GROUP unless
+# you want to use a group other than the default group for the given user.
+
+EXIM_GROUP=exim
+
+# Many sites define a user called "exim", with an appropriate default group,
+# and use
+#
+# EXIM_USER=exim
+#
+# while leaving EXIM_GROUP unspecified (commented out).
+
+
+#------------------------------------------------------------------------------
+# SPOOL_DIRECTORY defines the directory where all the data for messages in
+# transit is kept. It is strongly recommended that you define it here, though
+# it is possible to leave this till the run time configuration.
+
+# Exim creates the spool directory if it does not exist. The owner and group
+# will be those defined by EXIM_USER and EXIM_GROUP, and this also applies to
+# all the files and directories that are created in the spool directory.
+
+# Almost all installations choose this:
+
+SPOOL_DIRECTORY=/var/spool/exim

+
+
+#------------------------------------------------------------------------------
+# If you have set LOOKUP_LDAP=yes, you should set LDAP_LIB_TYPE to indicate
+# which LDAP library you have. Unfortunately, though most of their functions
+# are the same, there are minor differences. Currently Exim knows about four
+# LDAP libraries: the one from the University of Michigan (also known as
+# OpenLDAP 1), OpenLDAP 2, the Netscape SDK library, and the library that comes

+
+# LDAP_LIB_TYPE=OPENLDAP1
+LDAP_LIB_TYPE=OPENLDAP2
+# LDAP_LIB_TYPE=NETSCAPE
+# LDAP_LIB_TYPE=SOLARIS
+
+# If you don't set any of these, Exim assumes the original University of

+
+
+#------------------------------------------------------------------------------
+# The PCRE library is required for exim.  There is no longer an embedded

+
+#------------------------------------------------------------------------------
+# Additional libraries and include directories may be required for some

+# the command for linking Exim itself, not on any auxiliary programs. You
+# don't need to set LOOKUP_INCLUDE if the relevant directories are already

+
+LOOKUP_INCLUDE=-I/usr/include/mysql
+LOOKUP_LIBS=-L/usr/lib$(LIBDIRSUFFIX)/mysql -lldap -lmysqlclient -lsqlite3
+

+
+
+#------------------------------------------------------------------------------
+# Compiling Exim with content scanning support: If you want to compile Exim

+# The items in this section are those that are commonly changed according to
+# the sysadmin's preferences, but whose defaults are often acceptable. The
+# first five are concerned with security issues, where differing levels of
+# paranoia are appropriate in different environments. Sysadmins also vary in
+# their views on appropriate levels of defence in these areas. If you do not
+# understand these issues, go with the defaults, which are used by many sites.
+
+
+#------------------------------------------------------------------------------
+# Although Exim is normally a setuid program, owned by root, it refuses to run
+# local deliveries as root by default. There is a runtime option called
+# "never_users" which lists the users that must never be used for local
+# deliveries. There is also the setting below, which provides a list that
+# cannot be overridden at runtime. This guards against problems caused by
+# unauthorized changes to the runtime configuration. You are advised not to
+# remove "root" from this option, but you can add other users if you want. The
+# list is colon-separated. It must NOT contain any spaces.
+
+# FIXED_NEVER_USERS=root:bin:daemon
+FIXED_NEVER_USERS=root
+
+
+#------------------------------------------------------------------------------
+# By default, Exim insists that its configuration file be owned either by root
+# or by the Exim user. You can specify one additional permitted owner here.
+
+# CONFIGURE_OWNER=
+
+# If the configuration file is group-writeable, Exim insists by default that it
+# is owned by root or the Exim user. You can specify one additional permitted
+# group owner here.
+
+# CONFIGURE_GROUP=
+
+# If you specify CONFIGURE_OWNER or CONFIGURE_GROUP as a name, this is looked
+# up at build time, and the uid or gid number is built into the binary.
+# However, you can specify that the lookup is deferred until runtime. In this
+# case, it is the name that is built into the binary. You can do this by a
+# setting of the form:
+
+# CONFIGURE_OWNER=ref:mail
+# CONFIGURE_GROUP=ref:sysadmin
+
+# In other words, put "ref:" in front of the user or group name. Although this
+# costs a bit of resource at runtime, it is convenient to use this feature when
+# building binaries that are to be run on multiple systems where the names may

+#------------------------------------------------------------------------------
+# The -C option allows Exim to be run with an alternate runtime configuration
+# file. When this is used by root or the Exim user, root privilege is retained
+# by the binary (for any other caller, it is dropped). You can restrict the
+# location of alternate configurations by defining a prefix below. Any file
+# used with -C must then start with this prefix (except that /dev/null is also
+# permitted if the caller is root, because that is used in the install script).
+# If the prefix specifies a directory that is owned by root, a compromise of
+# the Exim account does not permit arbitrary alternate configurations to be
+# used. The prefix can be more restrictive than just a directory (the second
+# example).
+
+# ALT_CONFIG_PREFIX=/some/directory/
+# ALT_CONFIG_PREFIX=/some/directory/exim.conf-
+
+
+#------------------------------------------------------------------------------
+# If you uncomment the following line, only root may use the -C or -D options
+# without losing root privilege. The -C option specifies an alternate runtime
+# configuration file, and the -D option changes macro values in the runtime
+# configuration. Uncommenting this line restricts what can be done with these
+# options. A call to receive a message (either one-off or via a daemon) cannot
+# successfully continue to deliver it, because the re-exec of Exim to regain
+# root privilege will fail, owing to the use of -C or -D by the Exim user.
+# However, you can still use -C for testing (as root) if you do separate Exim
+# calls for receiving a message and subsequently delivering it.
+
+# ALT_CONFIG_ROOT_ONLY=yes
+
+
+#------------------------------------------------------------------------------
+# Uncommenting this option disables the use of the -D command line option,
+# which changes the values of macros in the runtime configuration file.
+# This is another protection against somebody breaking into the Exim account.
+
+# DISABLE_D_OPTION=yes
+
+
+#------------------------------------------------------------------------------
+# Exim has support for the AUTH (authentication) extension of the SMTP
+# protocol, as defined by RFC 2554. If you don't know what SMTP authentication
+# is, you probably won't want to include this code, so you should leave these
+# settings commented out. If you do want to make use of SMTP authentication,
+# you must uncomment at least one of the following, so that appropriate code is
+# included in the Exim binary. You will then need to set up the run time
+# configuration to make use of the mechanism(s) selected.
+
+AUTH_CRAM_MD5=yes
+AUTH_CYRUS_SASL=yes
+AUTH_DOVECOT=yes
+AUTH_PLAINTEXT=yes
+AUTH_SPA=yes
+
+
+#------------------------------------------------------------------------------
+# If you specified AUTH_CYRUS_SASL above, you should ensure that you have the
+# Cyrus SASL library installed before trying to build Exim, and you probably
+# want to uncomment the following line:
+
+AUTH_LIBS=-lsasl2
+
+
+#------------------------------------------------------------------------------
+# When Exim is decoding MIME "words" in header lines, most commonly for use
+# in the $header_xxx expansion, it converts any foreign character sets to the
+# one that is set in the headers_charset option. The default setting is
+# defined by this setting:
+
+HEADERS_CHARSET="ISO-8859-1"
+
+# If you are going to make use of $header_xxx expansions in your configuration
+# file, or if your users are going to use them in filter files, and the normal
+# character set on your host is something other than ISO-8859-1, you might
+# like to specify a different default here. This value can be overridden in
+# the runtime configuration, and it can also be overridden in individual filter
+# files.
+#
+# IMPORTANT NOTE: The iconv() function is needed for character code
+# conversions. Please see the next item...
+
+
+#------------------------------------------------------------------------------
+# Character code conversions are possible only if the iconv() function is
+# installed on your operating system. There are two places in Exim where this
+# is relevant: (a) The $header_xxx expansion (see the previous item), and (b)
+# the Sieve filter support. For those OS where iconv() is known to be installed
+# as standard, the file in OS/Makefile-xxxx contains
+#
+# HAVE_ICONV=yes
+#
+# If you are not using one of those systems, but have installed iconv(), you
+# need to uncomment that line above. In some cases, you may find that iconv()
+# and its header file are not in the default places. You might need to use
+# something like this:
+#
+# HAVE_ICONV=yes
+# CFLAGS=-O -I/usr/local/include
+# EXTRALIBS_EXIM=-L/usr/local/lib -liconv
+#
+# but of course there may need to be other things in CFLAGS and EXTRALIBS_EXIM
+# as well.
+
+
+#------------------------------------------------------------------------------
+# The passwords for user accounts are normally encrypted with the crypt()
+# function. Comparisons with encrypted passwords can be done using Exim's
+# "crypteq" expansion operator. (This is commonly used as part of the
+# configuration of an authenticator for use with SMTP AUTH.) At least one
+# operating system has an extended function called crypt16(), which uses up to
+# 16 characters of a password (the normal crypt() uses only the first 8). Exim
+# supports the use of crypt16() as well as crypt() but note the warning below.
+
+# You can always indicate a crypt16-encrypted password by preceding it with
+# "{crypt16}". If you want the default handling (without any preceding
+# indicator) to use crypt16(), uncomment the following line:
+
+# DEFAULT_CRYPT=crypt16
+
+# If you do that, you can still access the basic crypt() function by preceding
+# an encrypted password with "{crypt}". For more details, see the description
+# of the "crypteq" condition in the manual chapter on string expansions.
+
+# Some operating systems do not include a crypt16() function, so Exim has one
+# of its own, which it uses unless HAVE_CRYPT16 is defined. Normally, that will
+# be set in an OS-specific Makefile for the OS that have such a function, so
+# you should not need to bother with it.
+
+# *** WARNING *** WARNING *** WARNING *** WARNING *** WARNING ***
+# It turns out that the above is not entirely accurate. As well as crypt16()
+# there is a function called bigcrypt() that some operating systems have. This
+# may or may not use the same algorithm, and both of them may be different to
+# Exim's built-in crypt16() that is used unless HAVE_CRYPT16 is defined.
+#
+# However, since there is now a move away from the traditional crypt()
+# functions towards using SHA1 and other algorithms, tidying up this area of
+# Exim is seen as very low priority. In practice, if you need to, you can
+# define DEFAULT_CRYPT to the name of any function that has the same interface
+# as the traditional crypt() function.
+# *** WARNING *** WARNING *** WARNING *** WARNING *** WARNING ***

+
+#------------------------------------------------------------------------------
+# Exim can be built to support the SMTP STARTTLS command, which implements
+# Transport Layer Security using SSL (Secure Sockets Layer). To do this, you
+# must install the OpenSSL library package or the GnuTLS library. Exim contains
+# no cryptographic code of its own. Uncomment the following lines if you want
+# to build Exim with TLS support. If you don't know what this is all about,
+# leave these settings commented out.
+
+# This setting is required for any TLS support (either OpenSSL or GnuTLS)
+SUPPORT_TLS=yes
+
+# Uncomment this setting if you are using OpenSSL
+TLS_LIBS=-lssl -lcrypto
+
+# Uncomment these settings if you are using GnuTLS
+# USE_GNUTLS=yes
+# TLS_LIBS=-lgnutls -ltasn1 -lgcrypt
+
+# If you are running Exim as a server, note that just building it with TLS
+# support is not all you need to do. You also need to set up a suitable
+# certificate, and tell Exim about it by means of the tls_certificate
+# and tls_privatekey run time options. You also need to set tls_advertise_hosts
+# to specify the hosts to which Exim advertises TLS support. On the other hand,
+# if you are running Exim only as a client, building it with TLS support
+# is all you need to do.
+
+# Additional libraries and include files are required for both OpenSSL and
+# GnuTLS. The TLS_LIBS settings above assume that the libraries are installed
+# with all your other libraries. If they are in a special directory, you may
+# need something like
+
+# TLS_LIBS=-L/usr/local/openssl/lib -lssl -lcrypto
+# or
+# TLS_LIBS=-L/opt/gnu/lib -lgnutls -ltasn1 -lgcrypt
+
+# TLS_LIBS is included only on the command for linking Exim itself, not on any
+# auxiliary programs. If the include files are not in a standard place, you can
+# set TLS_INCLUDE to specify where they are, for example:
+
+# TLS_INCLUDE=-I/usr/local/openssl/include/
+# or
+# TLS_INCLUDE=-I/opt/gnu/include
+
+# You don't need to set TLS_INCLUDE if the relevant directories are already
+# specified in INCLUDE.
+
+
+#------------------------------------------------------------------------------
+# The default distribution of Exim contains only the plain text form of the
+# documentation. Other forms are available separately. If you want to install
+# the documentation in "info" format, first fetch the Texinfo documentation
+# sources from the ftp directory and unpack them, which should create files
+# with the extension "texinfo" in the doc directory. You may find that the
+# version number of the texinfo files is different to your Exim version number,
+# because the main documentation isn't updated as often as the code. For
+# example, if you have Exim version 4.43, the source tarball upacks into a
+# directory called exim-4.43, but the texinfo tarball unpacks into exim-4.40.
+# In this case, move the contents of exim-4.40/doc into exim-4.43/doc after you
+# have unpacked them. Then set INFO_DIRECTORY to the location of your info
+# directory. This varies from system to system, but is often /usr/share/info.
+# Once you have done this, "make install" will build the info files and
+# install them in the directory you have defined.
+
+# INFO_DIRECTORY=/usr/share/info
+
+
+#------------------------------------------------------------------------------
+# Exim log directory and files: Exim creates several log files inside a
+# single log directory. You can define the directory and the form of the
+# log file name here. If you do not set anything, Exim creates a directory
+# called "log" inside its spool directory (see SPOOL_DIRECTORY above) and uses
+# the filenames "mainlog", "paniclog", and "rejectlog". If you want to change
+# this, you can set LOG_FILE_PATH to a path name containing one occurrence of
+# %s. This will be replaced by one of the strings "main", "panic", or "reject"
+# to form the final file names. Some installations may want something like this:
+
+LOG_FILE_PATH=/var/log/exim/%s.log
+
+# which results in files with names /var/log/exim_mainlog, etc. The directory
+# in which the log files are placed must exist; Exim does not try to create
+# it for itself. It is also your responsibility to ensure that Exim is capable
+# of writing files using this path name. The Exim user (see EXIM_USER above)
+# must be able to create and update files in the directory you have specified.
+
+# You can also configure Exim to use syslog, instead of or as well as log
+# files, by settings such as these
+
+# LOG_FILE_PATH=syslog
+# LOG_FILE_PATH=syslog:/var/log/exim_%slog
+
+# The first of these uses only syslog; the second uses syslog and also writes
+# to log files. Do not include white space in such a setting as it messes up
+# the building process.
+
+
+#------------------------------------------------------------------------------
+# When logging to syslog, the following option caters for syslog replacements
+# that are able to accept log entries longer than the 1024 characters allowed
+# by RFC 3164. It is up to you to make sure your syslog daemon can handle this.
+# Non-printable characters are usually unacceptable regardless, so log entries
+# are still split on newline characters.
+
+# SYSLOG_LONG_LINES=yes
+
+# If you are not interested in the process identifier (pid) of the Exim that is
+# making the call to syslog, then comment out the following line.
+
+SYSLOG_LOG_PID=yes
+
+
+#------------------------------------------------------------------------------
+# Cycling log files: this variable specifies the maximum number of old
+# log files that are kept by the exicyclog log-cycling script. You don't have
+# to use exicyclog. If your operating system has other ways of cycling log
+# files, you can use them instead. The exicyclog script isn't run by default;
+# you have to set up a cron job for it if you want it.
+
+EXICYCLOG_MAX=10
+
+
+#------------------------------------------------------------------------------
+# The compress command is used by the exicyclog script to compress old log
+# files. Both the name of the command and the suffix that it adds to files
+# need to be defined here. See also the EXICYCLOG_MAX configuration.

+# Compiling in support for embedded Perl: If you want to be able to
+# use Perl code in Exim's string manipulation language and you have Perl
+# (version 5.004 or later) installed, set EXIM_PERL to perl.o. Using embedded
+# Perl costs quite a lot of resources. Only do this if you really need it.

+# Support for dynamically-loaded string expansion functions via ${dlfunc. If
+# you are using gcc the dynamically-loaded object must be compiled with the
+# -shared option, and you will need to add -export-dynamic to EXTRALIBS so
+# that the local_scan API is made available by the linker. You may also need

+
+# You probably need to add -lpam to EXTRALIBS, and in some releases of

+
+
+#------------------------------------------------------------------------------
+# Support for authentication via Radius is also available. The Exim support,
+# which is intended for use in conjunction with the SMTP AUTH facilities,
+# is included only when requested by setting the following parameter to the
+# location of your Radius configuration file:
+
+RADIUS_CONFIG_FILE=/etc/radiusclient/radiusclient.conf
+# RADIUS_CONFIG_FILE=/etc/radius.conf
+
+# If you have set RADIUS_CONFIG_FILE, you should also set one of these to
+# indicate which RADIUS library is used:
+
+RADIUS_LIB_TYPE=RADIUSCLIENT
+# RADIUS_LIB_TYPE=RADIUSCLIENTNEW
+# RADIUS_LIB_TYPE=RADLIB
+
+# RADIUSCLIENT is the radiusclient library; you probably need to add
+#   -lradiusclient to EXTRALIBS.
+#
+# The API for the radiusclient library was changed at release 0.4.0.
+# Unfortunately, the header file does not define a version number that clients
+# can use to support both the old and new APIs. If you are using version 0.4.0
+# or later of the radiusclient library, you should use RADIUSCLIENTNEW.
+#
+# RADLIB is the Radius library that comes with FreeBSD (the header file is
+#   called radlib.h); you probably need to add -lradius to EXTRALIBS.
+#
+# If you do not set RADIUS_LIB_TYPE, Exim assumes the radiusclient library,
+# using the original API.
+
+EXTRALIBS += -lradiusclient
+

+#------------------------------------------------------------------------------
+# Support for authentication via the Cyrus SASL pwcheck daemon is available.
+# Note, however, that pwcheck is now deprecated in favour of saslauthd (see

+# conjunction with the SMTP AUTH facilities, is included only when requested by
+# setting the following parameter to the location of the pwcheck daemon's
+# socket.
+#
+# There is no need to install all of SASL on your system. You just need to run
+# ./configure --with-pwcheck, cd to the pwcheck directory within the sources,
+# make and make install. You must create the socket directory (default

+#
+# USE_TCP_WRAPPERS=yes
+#
+# You may well also have to specify a local "include" file and an additional

+#------------------------------------------------------------------------------
+# The default action of the exim_install script (which is run by "make
+# install") is to install the Exim binary with a unique name such as
+# exim-4.43-1, and then set up a symbolic link called "exim" to reference it,
+# moving the symbolic link from any previous version. If you define NO_SYMLINK
+# (the value doesn't matter), the symbolic link is not created or moved. You
+# will then have to "turn Exim on" by setting up the link manually.
+
+NO_SYMLINK=yes
+
+
+#------------------------------------------------------------------------------
+# Another default action of the install script is to install a default runtime
+# configuration file if one does not exist. This configuration has a router for
+# expanding system aliases. The default assumes that these aliases are kept
+# in the traditional file called /etc/aliases. If such a file does not exist,
+# the installation script creates one that contains just comments (no actual
+# aliases). The following setting can be changed to specify a different
+# location for the system alias file.
+
+SYSTEM_ALIASES_FILE=/etc/exim/aliases
+
+
+#------------------------------------------------------------------------------
+# There are some testing options (-be, -bt, -bv) that read data from the
+# standard input when no arguments are supplied. By default, the input lines
+# are read using the standard fgets() function. This does not support line
+# editing during interactive input (though the terminal's "erase" character
+# works as normal). If your operating system has the readline() function, and
+# in addition supports dynamic loading of library functions, you can cause
+# Exim to use readline() for the -be testing option (only) by uncommenting the
+# following setting. Dynamic loading is used so that the library is loaded only
+# when the -be testing option is given; by the time the loading occurs,
+# Exim has given up its root privilege and is running as the calling user. This
+# is the reason why readline() is NOT supported for -bt and -bv, because Exim
+# runs as root or as exim, respectively, for those options. When USE_READLINE
+# is "yes", as well as supporting line editing, a history of input lines in the
+# current run is maintained.
+
+USE_READLINE=yes
+
+# You may need to add -ldl to EXTRALIBS when you set USE_READLINE=yes.
+# Note that this option adds to the size of the Exim binary, because the
+# dynamic loading library is not otherwise included.

+# In some operating systems, the value of the TMPDIR environment variable

+# The maximum number of named lists of each type (address, domain, host, and
+# local part) can be increased by changing this value. It should be set to
+# a multiple of 16.
+
+# MAX_NAMED_LIST=16
+
+
+#------------------------------------------------------------------------------
+# Network interfaces: Unless you set the local_interfaces option in the runtime
+# configuration file to restrict Exim to certain interfaces only, it will run
+# code to find all the interfaces there are on your host. Unfortunately,
+# the call to the OS that does this requires a buffer large enough to hold
+# data for all the interfaces - it was designed in the days when a host rarely
+# had more than three or four interfaces. Nowadays hosts can have very many
+# virtual interfaces running on the same hardware. If you have more than 250
+# virtual interfaces, you will need to uncomment this setting and increase the
+# value.
+
+# MAXINTERFACES=250
+
+
+#------------------------------------------------------------------------------
+# Per-message logs: While a message is in the process of being delivered,
+# comments on its progress are written to a message log, for the benefit of
+# human administrators. These logs are held in a directory called "msglog"
+# in the spool directory. Its mode defaults to 0750, but can be changed here.
+# The message log directory is also used for storing files that are used by
+# transports for returning data to a message's sender (see the "return_output"
+# option for transports).
+
+# MSGLOG_DIRECTORY_MODE=0750
+
+
+#------------------------------------------------------------------------------
+# There are three options which are used when compiling the Perl interface and
+# when linking with Perl. The default values for these are placed automatically
+# at the head of the Makefile by the script which builds it. However, if you
+# want to override them, you can do so here.
+
+# PERL_CC=
+# PERL_CCOPTS=
+# PERL_LIBS=
+
+
+#------------------------------------------------------------------------------
+# Identifying the daemon: When an Exim daemon starts up, it writes its pid
+# (process id) to a file so that it can easily be identified. The path of the
+# file can be specified here. Some installations may want something like this:
+
+PID_FILE_PATH=/var/run/exim.pid
+
+# If PID_FILE_PATH is not defined, Exim writes a file in its spool directory
+# using the name "exim-daemon.pid".
+
+# If you start up a daemon without the -bd option (for example, with just
+# the -q15m option), a pid file is not written. Also, if you override the
+# configuration file with the -oX option, no pid file is written. In other
+# words, the pid file is written only for a "standard" daemon.
+
+
+#------------------------------------------------------------------------------
+# If Exim creates the spool directory, it is given this mode, defaulting in the
+# source to 0750.
+
+# SPOOL_DIRECTORY_MODE=0750
+
+
+#------------------------------------------------------------------------------
+# The mode of files on the input spool which hold the contents of messages can
+# be changed here. The default is 0640 so that information from the spool is
+# available to anyone who is a member of the Exim group.
+
+# SPOOL_MODE=0640
+
+
+#------------------------------------------------------------------------------
+# Moving frozen messages: If the following is uncommented, Exim is compiled
+# with support for automatically moving frozen messages out of the main spool
+# directory, a facility that is found useful by some large installations. A
+# run time option is required to cause the moving actually to occur. Such
+# messages become "invisible" to the normal management tools.
+
+# SUPPORT_MOVE_FROZEN_MESSAGES=yes
+
+
+#------------------------------------------------------------------------------
+# Disabling the use of fsync(): DO NOT UNCOMMENT THE FOLLOWING LINE unless you
+# really, really, really know what you are doing. And even then, think again.
+# You should never uncomment this when compiling a binary for distribution.
+# Use it only when compiling Exim for your own use.
+#
+# Uncommenting this line enables the use of a runtime option called
+# disable_fsync, which can be used to stop Exim using fsync() to ensure that
+# files are written to disc before proceeding. When this is disabled, crashes
+# and hardware problems such as power outages can cause data to be lost. This
+# feature should only be used in very exceptional circumstances. YOU HAVE BEEN

+.SH NAME
+exicyclog \- Cycle exim's logfiles
+.SH SYNOPSIS
+.B eximcyclog
+.SH DESCRIPTION
+The
+.B exicyclog
+script can be used to cycle (rotate)
+.I mainlog
+and
+.I rejectlog
+files.
+This is not necessary if only syslog is being used.
+Some operating systems have their own standard mechanisms for log cycling,
+and these can be used instead of
+.B exicyclog
+if preferred.
+
+Each time
+.B exicyclog
+is run the file names get \(oqshuffled down\(cq by one.
+If the main log file name is mainlog (the default) then when
+.B exicyclog
+is run mainlog becomes mainlog.01, the previous mainlog.01 becomes mainlog.02
+and so on, up to a limit which is set in the script, and which defaults to 10.
+Reject logs are handled similarly.
+
+If no mainlog file exists, the script does nothing.
+Files that \(oqdrop off\(cq the end are deleted.
+All files with numbers greater than 01 are compressed, using a compression
+command which is configured by the COMPRESS_COMMAND setting in
+Local/Makefile.
+It is usual to run \(lqexicyclog\(rq daily from a root \(lqcrontab\(rq entry
+of the form
+
+  1 0 * * * su exim \-c /usr/exim/bin/exicyclog
+
+assuming you have used the name \(oqexim\(cq for the Exim user.
+You can run
+.B exicyclog
+as root if you wish, but there is no need.

+.SH NAME
+EXIGREP \- Search Exim's main log
+.SH SYNOPSIS
+.B exigrep
+.I [\-l] pattern [log file] ...
+
+.SH DESCRIPTION
+The
+.B exigrep
+utility is a Perl script that searches one or more main log files for
+entries that match a given pattern.
+When it finds a match, it extracts all the log entries for the relevant
+message, not just those that match the pattern.
+Thus,
+.B exigrep
+can extract complete log entries for a given message, or all mail for a given
+user, or for a given host, for example.
+
+The
+.I \-l
+flag means \(oqliteral\(cq, that is, treat all characters in the pattern as
+standing for themselves.
+Otherwise the pattern must be a Perl regular expression.
+The pattern match is case-insensitive.
+If no file names are given on the command line, the standard input is
+read.
+
+If the location of a
+.B zcat
+command is known from the definition of ZCAT_COMMAND in Local/Makefile,
+.B exigrep
+automatically passes any file whose
+name ends in COMPRESS_SUFFIX through
+.B zcat
+as it searches it.
+

+.SH NAME
+exim_checkaccess \- Check address acceptance from given IP
+.SH SYNOPSIS
+.B exim_checkaccess
+.I IP-address email@address [more Exim options]
+
+.SH DESCRIPTION
+.B Exim's
+.I \-bh
+command line argument allows you to run a fake SMTP session with debugging
+output, in order to check what Exim is doing when it is applying policy
+controls to incoming SMTP mail.
+However, not everybody is sufficiently familiar with the SMTP protocol to
+be able to make full use of \-bh, and sometimes you just want to answer the
+question \(lqDoes this address have access?\(rq without bothering with any
+further details.
+
+The
+.B exim_checkaccess
+utility is a \(oqpackaged\(cq version of
+.I \-bh.
+It takes two arguments, an IP address and an email address:
+
+  exim_checkaccess 10.9.8.7 A.User@a.domain.example
+
+The utility runs a call to
+.B Exim
+with the \-bh option, to test whether the given email address would be
+accepted in a RCPT command in a TCP/IP connection from the host with the
+given IP address.
+The output of the utility is either the word \(oqaccepted\(cq, or the SMTP error
+response, for example:
+
+  Rejected:
+    550 Relay not permitted
+
+When running this test, the utility uses \(lq<>\(rq as the envelope sender
+address for the MAIL command, but you can change this by providing additional
+options.  These are passed directly to the Exim command.
+For example, to specify that the test is to be run with the sender address
+\(lqhimself@there.example\(rq you can use:
+
+  exim_checkaccess 10.9.8.7 A.User@a.domain.example \\
+                   \-f himself@there.example
+
+Note that these additional Exim command line items must be given after the
+two mandatory arguments.
+

+.SH NAME
+exim_db \- Manage Exim's hint databases (exim_dumpdb, exim_fixdb, exim_tidydb)
+.SH SYNOPSIS
+.B exim_dumpdb
+.I spooldir database
+.br
+.B exim_fixdb
+.I spooldir database
+.br
+.B exim_tidydb
+.I [\-f] [\-t time] spooldir database
+
+.SH DESCRIPTION
+Three utility programs are provided for maintaining the DBM files that
+Exim uses to contain its delivery hint information.
+Each program requires two arguments.
+The first specifies the name of Exim's spool directory, and the second is
+the name of the database it is to operate on.
+These are as follows:
+.TP
+.B retry
+the database of retry information
+.TP
+.B wait\-<transport name>
+databases of information about messages waiting for remote hosts
+.TP
+.B misc
+other hints data (for example, for serializing ETRN runs)
+.P
+The entire contents of a database are written to the standard output by the
+.B exim_dumpdb
+program, which has no options or arguments other than the spool
+and database names.
+For example, to dump the retry database:
+
+.I exim_dumpdb /var/spool/exim retry
+
+Two lines of output are produced for each entry:
+.nf
+    T:mail.ref.example:192.168.242.242 146 77 Connection refused
+  31-Oct-1995 12:00:12  02-Nov-1995 12:21:39  02-Nov-1995 20:21:39 *
+
+.fi
+The first item on the first line is the key of the record.
+It starts with one of the letters R, or T, depending on whether it refers
+to a routing or transport retry.
+For a local delivery, the next part is the local address; for a remote
+delivery it is the name of the remote host, followed by its failing IP
+address (unless \(lqno_retry_include_ip_address\(rq is set on the smtp
+transport).
+Then there follows an error code, an additional error code, and a
+textual description of the error.
+
+The three times on the second line are the time of first failure, the time of
+the last delivery attempt, and the computed time for the next attempt.
+The line ends with an asterisk if the cutoff time for the last retry rule
+has been exceeded.
+
+Each output line from
+.B exim_dumpdb
+for the
+.I wait\-xxx
+databases consists of a host name followed by a list of ids for messages
+that are or were waiting to be delivered to that host.
+If there are a very large number for any one host, continuation records,
+with a sequence number added to the host name, may be seen.
+The data in these records is often out of date, because a message may be
+routed to several alternative hosts, and Exim makes no effort to keep
+cross-references.
+
+The
+.B exim_tidydb
+utility program is used to tidy up the contents of the hints databases.
+If run with no options, it removes all records from a database that are
+more than 30 days old.
+The cutoff date can be altered by means of the \-t option, which must be
+followed by a time.
+For example, to remove all records older than a week from the retry
+database:
+
+.I exim_tidydb \-t 7d /var/spool/exim retry
+
+Both the
+.I wait\-xxx
+and
+.I retry
+databases contain items that involve message ids.
+In the former these appear as data in records keyed by host - they were
+messages that were waiting for that host - and in the latter they are the
+keys for retry information for messages that have suffered certain types
+of error.
+When \(lqexim_tidydb\(rq is run, a check is made to ensure that message ids in
+database records are those of messages that are still on the queue.
+Message ids for messages that no longer exist are removed from \(lqwait\-\(rqxxx
+records, and if this leaves any records empty, they are deleted.
+For the \(lqretry\(rq database, records whose keys are non-existent message
+ids are removed.
+The
+.B exim_tidydb
+utility outputs comments on the standard output whenever it removes
+information from the database.
+
+Removing records from a DBM file does not normally make the file smaller, but
+all the common DBM libraries are able to re-use the space that is released.
+It is therefore suggested that
+.B exim_tidydb
+be run periodically on all the hints databases, but at a quiet time of day,
+because it requires a database to be locked (and therefore inaccessible to
+Exim) while it does its work.
+
+The
+.B exim_fixdb
+program is a utility for interactively modifying databases.
+Its main use is for testing Exim, but it might also be occasionally useful
+for getting round problems in a live system.
+It has no options, and its interface is somewhat crude.
+On entry, it prompts for input with a right angle-bracket.
+A key of a database record can then be entered, and the data for that
+record is displayed.
+
+If \(oqd\(cq is typed at the next prompt, the entire record is deleted.
+For all except the
+.I retry
+database, that is the only operation that can be carried out.
+For the
+.I retry
+database, each field is output preceded by a number, and data for individual
+fields can be changed by typing the field number followed by new data, for
+example:
+
+  > 4 951102:1000
+
+resets the time of the next delivery attempt.
+Time values are given as a sequence of digit pairs for year, month, day,
+hour, and minute.
+Colons can be used as optional separators.

+.SH NAME
+exim_dbmbuild \- Build a DBM file.
+.SH SYNOPSIS
+.B exim_dbmbuild
+.I [\-nolc] [\-nozero] [\-noduperr] [\-nowarn] inputfile|\- outputfile
+
+.SH DESCRIPTION
+The
+.B exim_dbmbuild
+program reads an input file containing keys and data in
+the format used by the
+.I lsearch
+lookup (see section 9.1).
+It writes a DBM file using the lower-cased alias names as keys and the
+remainder of the information as data.
+The lower-casing can be prevented by calling the program with the
+.I \-nolc
+option.
+
+A terminating zero is included as part of the key string.
+This is expected by the dbm lookup type.
+However, if the option
+.I \-nozero
+is given, 
+.B exim_dbmbuild
+creates files without terminating zeroes in either the key strings or the
+data strings.
+The 
+.I dbmnz
+lookup type can be used with such files.
+
+The program requires two arguments: the name of the input file (which can
+be a single hyphen to indicate the standard input), and the name of the
+output file.
+It creates the output under a temporary name, and then renames it if all
+went well.
+If the native DB interface is in use (USE_DB is set in a compile-time
+configuration file - this is common in free versions of Unix) the two file
+names must be different, because in this mode the Berkeley DB functions
+create a single output file using exactly the name given.
+For example,
+
+  exim_dbmbuild /etc/aliases /etc/aliases.db
+
+reads the system alias file and creates a DBM version of it in
+/etc/aliases.db.
+
+In systems that use the
+.I ndbm
+routines (mostly proprietary versions of Unix), two files are used, with the
+suffixes .dir and .pag.
+In this environment, the suffixes are added to the second argument of
+.B exim_dbmbuild,
+so it can be the same as the first.
+This is also the case when the Berkeley functions are used in
+compatibility mode (though this is not recommended), because in that case
+it adds a .db suffix to the file name.
+
+If a duplicate key is encountered, the program outputs a warning, and when
+it finishes, its return code is 1 rather than zero, unless the
+.I \-noduperr
+option is used.
+By default, only the first of a set of duplicates is used - this makes it
+compatible with lsearch lookups.
+There is an option
+.I \-lastdup
+which causes it to use the data for the last duplicate instead.
+There is also an option
+.I \-nowarn,
+which stops it listing duplicate keys to \(lqstderr\(rq.
+For other errors, where it doesn't actually make a new file, the return
+code is 2.

+.SH NAME
+exim_lock \- Mailbox maintenance
+.SH SYNOPSIS
+.B exim_lock
+.RI [ options ] mailbox-file
+
+.SH DESCRIPTION
+The
+.B exim_lock
+utility locks a mailbox file using the same algorithm as Exim.
+For a discussion of locking issues, see section 25.2.
+.B exim_lock
+can be used to prevent any modification of a mailbox by Exim or a user
+agent while investigating a problem.
+The utility requires the name of the file as its first argument.
+If the locking is successful, the second argument is run as a command
+(using C's \(lqsystem()\(rq function); if there is no second argument, the value
+of the SHELL environment variable is used; if this is unset or empty,
+/bin/sh is run.
+When the command finishes, the mailbox is unlocked and the utility ends.
+The following options are available:
+.TP
+.I \-fcntl
+Use \(lqfcntl()\(rq locking on the open mailbox.
+.TP
+.I \-interval
+This must be followed by a number, which is a number of seconds; it
+sets the interval to sleep between retries (default 3).
+.TP
+.I \-lockfile
+Create a lock file before opening the mailbox.
+.TP
+.I \-mbx
+Lock the mailbox using MBX rules.
+.TP
+.I \-q
+Suppress verification output.
+.TP
+.I \-retries
+This must be followed by a number; it sets the number of times to try
+to get the lock (default 10).
+.TP
+.I \-timeout
+This must be followed by a number, which is a number of seconds; it
+sets a timeout to be used with a blocking \(lqfcntl()\(rq lock.
+If it is not set (the default), a non-blocking call is used.
+.TP
+.I \-v
+Generate verbose output.
+
+If none of
+.I \-fcntl, \-lockfile
+or
+.I \-mbx
+are given, the default is to create a lock file and also use \(lqfcntl()\(rq locking
+on the mailbox, which is the same as
+.B Exim's
+default.
+The use of
+.I \-fcntl
+requires that the file be writable; the use
+of
+.I \-lockfile
+requires that the directory containing the file be writable.
+Locking by lock file does not last for ever; Exim assumes that a lock file
+is expired if it is more than 30 minutes old.
+
+The
+.I \-mbx
+option is mutually exclusive with
+.I \-fcntl.
+It causes a shared lock to be taken out on the open mailbox, and an
+exclusive lock on the file /tmp/.n.m where n and m are the device number
+and inode number of the mailbox file.
+When the locking is released, if an exclusive lock can be obtained for the
+mailbox, the file in /tmp is deleted.
+
+The default output contains verification of the locking that takes place.
+The
+.I \-v
+option causes some additional information to be given.
+The
+.I \-q
+option suppresses all output except error messages.
+.PP
+A command such as
+
+  exim_lock /var/spool/mail/spqr
+
+runs an interactive shell while the file is locked, whereas
+
+  exim_lock \-q /var/spool/mail/spqr <<End
+  <some commands>
+  End
+
+runs a specific non-interactive sequence of commands while the file is
+locked, suppressing all verification output.
+A single command can be run by a command such as
+
+  exim_lock \-q /var/spool/mail/spqr \
+    "cp /var/spool/mail/spqr /some/where"
+
+Note that if a command is supplied, it must be entirely contained within
+the second argument - hence the quotes.

+.SH NAME
+exinext \- Finding individual retry times
+.SH SYNOPSIS
+.B exinext
+.I address|message-id
+
+.SH DESCRIPTION
+A utility called
+.B exinext
+(mostly a Perl script) provides the ability to fish specific information
+out of the retry database.
+Given a mail domain (or a complete address), it looks up the hosts for
+that domain, and outputs any retry information for the hosts or for the
+domain.
+At present, the retry information is obtained by running
+.B exim_dumpdb
+(see below) and processing the output.
+For example:
+
+  exinext piglet@milne.fict.example
+  kanga.milne.fict.example:192.168.8.1 error 146: Connection refused
+    first failed: 21-Feb-1996 14:57:34
+    last tried:   21-Feb-1996 14:57:34
+    next try at:  21-Feb-1996 15:02:34
+  roo.milne.fict.example:192.168.8.3 error 146: Connection refused
+    first failed: 20-Jan-1996 13:12:08
+    last tried:   21-Feb-1996 11:42:03
+    next try at:  21-Feb-1996 19:42:03
+    past final cutoff time
+
+You can also give
+.B exinext
+a local part, without a domain, and it will give any retry information for
+that local part in your default domain.
+A message id can be used to obtain retry information pertaining to a
+specific message.
+This exists only when an attempt to deliver a message to a remote host
+suffers a message-specific error (see section 42.2).
+.B exinext
+is not particularly efficient, but then it isn't expected to be run very often.

+.SH NAME
+exiqsumm \- Summarising the queue
+.SH SYNOPSIS
+.B exiqsumm
+.I [\-a] [\-c]
+
+.SH DESCRIPTION
+The
+.B exiqsumm
+utility is a Perl script which reads the output of
+.I exim \-bp
+and produces a summary of the messages on the queue.
+Thus, you use it by running a command such as
+
+  exim \-bp | exiqsumm
+
+The output consists of one line for each domain that has messages waiting
+for it, as in the following example:
+
+    3   2322   74m   66m  msn.com.example
+
+This lists the number of messages for the domain, their total volume, and
+the length of time that the oldest and the newest messages have been
+waiting.
+By default the output is sorted on the domain name, but
+.B exiqsumm
+has the options
+.I \-a
+and
+.I \-c,
+which cause the output to be sorted by oldest message and by count of
+messages, respectively.
+
+The output of
+.I exim \-bp
+contains the original addresses in the message, so this also applies to
+the output from
+.B exiqsumm.
+No domains from addresses generated by aliasing or forwarding are included
+(unless the \(lqone_time\(rq option of the redirect router has been used to
+convert them into \(oqtop level\(cq addresses).

+.SH NAME
+exiwhat \- Finding out what Exim processes are doing
+.SH SYNOPSIS
+.B exiwhat
+
+.SH DESCRIPTION
+On operating systems that can restart a system call after receiving a
+signal (most modern OS), an 
+.B Exim
+process responds to the SIGUSR1 signal by writing a line describing what
+it is doing to the file exim\-process.info in the Exim spool directory.
+The
+.B exiwhat
+script sends the signal to all 
+.B Exim
+processes it can find, having first emptied the file.
+It then waits for one second to allow the
+.B Exim
+processes to react before displaying the results.
+In order to run 
+.B exiwhat
+successfully you have to have sufficient privilege to send the signal to
+the
+.B Exim
+processes, so it is normally run as root.
+
+Unfortunately, the
+.B ps
+command which
+.B exiwhat
+uses to find
+.B Exim
+processes varies in different operating systems.
+Not only are different options used, but the format of the output is
+different.
+For this reason, there are some system configuration options that configure
+exactly how
+.B exiwhat
+works.
+If it doesn't seem to be working for you, check the following compile-time

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
