+
+		    HOW TO BUILD AND INSTALL DISCOUNT
+
+1) Unpacking the distribution
+
+The DISCOUNT sources are distributed in tarballs.  After extracting from
+the tarball, you should end up with all the source and build files in the
+directory
+		discount-(version)
+
+2) Installing the distribution
+
+DISCOUNT uses configure.sh to set itself up for compilation.   To run
+configure, just do ``./configure.sh'' and it will check your system for
+build dependencies and build makefiles for you.   If configure.sh finishes
+without complaint, you can then do a ``make'' to compile everything and a
+``make install'' to install the binaries.
+
+Configure.sh has a few options that can be set:
+
+--src=DIR		where the source lives (.)
+--prefix=DIR		where to install the final product (/usr/local)
+--execdir=DIR		where to put executables (prefix/bin)
+--sbindir=DIR		where to put static executables (prefix/sbin)
+--confdir=DIR		where to put configuration information (/etc)
+--libdir=DIR		where to put libraries (prefix/lib)
+--libexecdir=DIR	where to put private executables
+--mandir=DIR		where to put manpages
+--enable-dl-tag	Use the DL tag extension
+--enable-pandoc-header	Use pandoc-style header blocks
+--enable-superscript	A^B expands to A<sup>B</sup>
+--enable-amalloc	Use a debugging memory allocator (to detect leaks)
+--relaxed-emphasis	Don't treat _ in the middle of a word as emphasis
+--with-tabstops=N	Set tabstops to N characters (default is 4)
+
+3) Installing sample programs and manpages
+
+The standard ``make install'' rule just installs the binaries. If you
+want to install the sample programs, they are installed with
+``make install.samples'';  to install manpages, ``make install.man''.
+A shortcut to install everything is ``make install.everything''

+# *Discount* Markdown compiler on Plan 9
+
+## Build
+
+	% CONFIG='--enable-all-features' mk config
+	% mk install
+	% markdown -V
+	markdown: discount X.Y.Z DL_TAG HEADER DEBUG SUPERSCRIPT RELAXED DIV
+
+`--enable-all-features` may be replaced by zero or more of:
+
+		--enable-dl-tag		Use the DL tag extension
+		--enable-pandoc-header	Use pandoc-style header blocks
+		--enable-superscript	A^B becomes A<sup>B</sup>
+		--enable-amalloc	Enable memory allocation debugging
+		--relaxed-emphasis	underscores aren't special in the middle of words
+		--with-tabstops=N	Set tabstops to N characters (default is 4)
+		--enable-div		Enable >%id% divisions
+		--enable-alpha-list	Enable (a)/(b)/(c) lists
+		--enable-all-features	Turn on all stable optional features
+
+## Notes
+
+The supplied mkfile merely drives Discount's own configure script and
+then APE's *psh* environment to build the Discount source, then copies
+the result(s) to locations appropriate for system-wide use on Plan 9.
+There are a few other *mk*(1) targets:
+
+`install.libs`: Discount includes a C library and header.
+Installation is optional.  Plan 9 binaries are statically linked.
+
+`install.man`: Add manual pages for markdown(1) and (6).
+
+`install.progs`: Extra programs.  *makepage* writes complete XHTML
+documents, rather than fragments.  *mkd2html* is similar, but produces
+HTML.
