+This is the "OpenDoas" port of OpenBSD's doas.
+
+The doas utility is a program originally written for OpenBSD that
+allows a user to run a command as though they were another user,
+typically root. doas acts as an alternative to sudo, with simple
+configuration syntax and a smaller code base for ease of security
+auditing.
+
+Please note that running this SlackBuild will install doas with SUID
+root.
+
+To get started, write a configuration file at /etc/doas.conf. As an
+example, including the line:
+
+  permit :wheel as root
+
+will allow all users in the wheel group to act as root with doas.
+Consult the doas.conf(5) man page for further details.
+
+The parameter "keepenv" in /etc/doas.conf allows for opening graphical
+applications with doas:
+
+  permit keepenv gene as root
+
+"exec dbus-launch --exit-with-session" may be required for xinit in
+Slackware 14.2. An alternative is to run "export $(dbus-launch)" after
+starting the X session. As with su, KDE 4 graphical applications may
+fail to open with doas.
+
+Running this SlackBuild without parameters will provide a build of
+OpenDoas with shadow support if PAM is not installed, and with PAM 
+support if PAM is installed. Password persistence is disabled by
+default.
+
+To enable timestamp-based password persistence, call the SlackBuild
+with PERSIST=yes:
+
+  PERSIST=yes ./opendoas.SlackBuild
+
+In addition, ensure that the appropriate user or group line in
+/etc/doas.conf includes the "persist" option, as in this example:
+
+  permit persist jane as root
+
+Please note that upstream considers timestamp-based password
+persistence to be "new and potentially dangerous."
+
+For users with PAM installed, enable shadow authentication instead by
+calling the SlackBuild with PAM=no:
+
+  PAM=no ./opendoas.SlackBuild
+
+If /etc/pam.d/other and /etc/pam.d/system-auth are unmodified from the
+state in which they are shipped in -current, doas will run with PAM
+support if so compiled. Otherwise, doas may require a dedicated file at
+/etc/pam.d/doas to use PAM authentication.
+
+To allow OpenDoas to write a new PAM configuration file for doas, call
+the SlackBuild with PAM_FILE=yes:
+
+  PAM_FILE=yes ./opendoas.SlackBuild
+
+Upstream will not include PAM configuration files in releases of
+OpenDoas beyond 6.8.1.
+
+opendoas has no outside dependencies on Slackware 14.2 and adds no
+users or groups. opendoas conflicts with all other ports of doas.

+# 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 ':' except on otherwise blank lines.

+opendoas: doas is a sudo alternative originally written for OpenBSD. It allows
+opendoas: a user to run a command as a different user, most often root. doas
+opendoas: offers simple configuration syntax; create a config file at
+opendoas: /etc/doas.conf to get started. See doas.conf(5).
+opendoas: The opendoas package conflicts with all other ports of doas.
+opendoas: The opendoas package does not conflict with sudo.
