# The `debug' target 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.
#
# The `build-env' 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.
