+z88dk (C cross compiler targetting the Z80)
+
+z88dk is a z80 C cross compiler supplied with an assembler/linker and
+a set of libraries implementing the C standard library for a number of
+different z80 based machines. The name z88dk originates from the time when
+the project was founded and targetted only the Cambridge z88 portable.
+
+Very little documentation is shipped with z88dk, and what's present is
+often outdated. For more extensive and updated docs, see the z88dk wikis:

+.SH NAME
+\fBcopt \fP- peephole optimizer
+.SH SYSNOPIS
+copt file \.\.\.
+.SH DESCRIPTION
+copt is a general-purpose peephole optimizer. It reads
+code from its standard input and writes an improved version to its standard output. 
+copy reads the named files for its optimizations, which are encoded as follows:
+.PP
+.nf
+.fam C
+          <pattern for input line 1>
+          <pattern for input line 2>
+           \.\.\.
+          <pattern for input line n>
+          =
+          <pattern for output line 1>
+          <pattern for output line 2>
+           \.\.\.
+          <pattern for output line m>
+          <blank line>
+
+.fam T
+.fi
+Pattern matching uses literal string comparison, with one
+exception: ``%%'' matches the ``%'' character, and ``%''
+followed by a digit matches everything up to the next
+occurrence of the next pattern character, though all
+occurrences of %\fIn\fP must denote the same string. For example,
+the pattern ``%1=%1.'' matches exactly those strings
+that begin with a string X, followed by a ``='' (the
+first), followed by a second occurrence of X, followed by
+a period. In this way, the input/output pattern
+.PP
+.nf
+.fam C
+          mov $%1,r%2
+          mov *r%2,r%2
+          =
+          mov %1,r%2
+
+.fam T
+.fi
+commands copt to replace runs like
+.PP
+.nf
+.fam C
+          mov $_a,r3
+          mov *r3,r3
+
+.fam T
+.fi
+with
+.PP
+.nf
+.fam C
+          mov _a,r3
+
+.fam T
+.fi
+Note that a tab or newline can terminate a %\fBn\fP variable.
+.PP
+copt compares each run of input patterns with the current
+input instruction and its predecessors. If no match is
+found, it advances to the next input instruction and tries
+again. Otherwise, it replaces the input instructions with
+the corresponding output patterns, pattern variables
+instantiated,and resumes its search with the \fIfirst\fP
+instruction of the replacement. copt matches input patterns
+in reverse order to cascade optimizations without
+backing up.
+.SH BUGS
+Errors in optimization files are always possible.

+.SH NAME
+\fBz88dk \fP- The z88 Development Kit.
+\fB
+.SH DESCRIPTION
+
+The z88 Development Kit (hereafter known as z88dk) is an advanced set
+of tools allowing the production of complex programs for z80 based
+computers in either C or assembly language.
+The name z88dk originates from the time when the project was founded and targetted only the Cambridge z88 portable.
+.RE
+.PP
+The compiler featured in z88dk is much enhanced Small C compiler, the compiler accepts many features
+of ANSI C and is only deficient in a few areas where implementation on a z80 processor might prove
+inefficient. The compiler performs simple optimizations, but the bulk of the optimization is done by
+a set of peep-hole rules, which will typically reduce the size of a large project by up to a third.
+.RS
+.PP
+The libraries supplied with z88dk are designed to be as generic as possible, indeed it is possible
+to port to a new machine simply by supplying two library routines and some startup code. It is hoped
+that one day z88dk will support as many z80 based machines as there is information available and sufficient interest in. 
+.PP
+z88dk contains usable tools:
+.IP \(bu 3
+zcc - the frontend of z88dk is called zcc, it is this that you should call if you want to do any compilations.
+.IP \(bu 3
+z80asm - Z80 assembler compiler
+.IP \(bu 3
+copt - Z80 asm optimizer code
+.IP \(bu 3
+appmake - produce files which are suitable for use in emulators or on the real hardware
+.IP \(bu 3
+sccz80 - Small-C/Plus compiler

+# 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.

+z88dk: z88dk (C cross compiler targetting the Z80)
+z88dk:
+z88dk: z88dk is a z80 C cross compiler supplied with an assembler/linker
+z88dk: and a set of libraries implementing the C standard library for a
+z88dk: number of different z80 based machines. The name z88dk originates
+z88dk: from the time when the project was founded and targetted only the
+z88dk: Cambridge z88 portable.
