Makefile

# Interesting make targets:
# - exe: Just the executable. This is the default.
# - src: Source tarball.
# - pkg: Cygwin package.
# - zip: Zip for standalone release.
# - pdf: PDF version of the manual page.
# - clean: Delete generated files.
#
# Variables intended for setting on the make command line.
# - TARGET: target triple for cross compiling
# - RELEASE: release number for packaging
# - DEBUG: define to enable debug build
# - DMALLOC: define to enable the dmalloc heap debugging library
#
# The values of DEBUG and DMALLOC variables do not matter, it's just about
# whether they're defined, so e.g. 'make DEBUG=1' will trigger a debug build.
