Discount Markdown compiler on Plan 9

Build

One line

% mk install
% markdown -V
markdown: discount X.Y.Z GHC=INPUT

Stepwise

% CONFIG='--with-tabstops=7' mk config
% mk
% mk test
% mk install
% markdown -V
markdown: discount X.Y.Z TAB=7 GHC=INPUT

See ../configure.sh and ../pgm_options.c for other config options.

Other mk(1) targets

• clean: Delete built objects from source directory.
• nuke: Delete built objects and generated configuration.
• install.libs: Discount includes a C library and header. Installation is optional. Plan 9 binaries are statically linked.
• install.man: Add markdown in manual sections 1, 2, and 6.
• install.progs: Extra programs. makepage writes complete XHTML documents, rather than fragments. mkd2html is similar, but produces HTML.
• installall: Do all install* targets above.
• uninstall: Remove anything added by install* targets above.

Notes

This is not a port from POSIX to native Plan 9 APIs. The supplied mkfile drives Discount's own ../configure.sh and the ../Makefile it generates through Plan 9's ANSI/POSIX Environment (APE) (in pcc(1)) to build the Discount source, then copies the results to locations appropriate for system-wide use on Plan 9.
