# Public targets:
#
# debug:
#	outputs the values of some commonly used variables and the
#	contents of some files which are useful for tracking bugs,
#	especially for packages that use the GNU autotools.
#
# build-env:
#	This target is intended to be used interactively when
#	debugging build problems. It runs a shell in exactly the same
#	environment as in the default do-build target, starting in
#	WRKSRC.
