# This file checks whether a package can be built in the current pkgsrc
# environment. It checks the following variables:
#
# * NOT_FOR_COMPILER, ONLY_FOR_COMPILER
# * NOT_FOR_PLATFORM, ONLY_FOR_PLATFORM
# * NOT_FOR_BULK_PLATFORM
# * NOT_FOR_UNPRIVILEGED, ONLY_FOR_UNPRIVILEGED
# * PKG_FAIL_REASON, PKG_SKIP_REASON
#

#
# NO_SKIP
# When defined, the checks in this file are skipped. It is called
# NO_SKIP because the code that skips building the package should
# _not_ be run.
