#
# This file checks that the extracted shell programs don't contain
# bashisms or other constructs that only work on some platforms.
#
# User-settable variables:
#
# CHECK_PORTABILITY
#	Whether to enable the portability checks.
#
#	Default value: yes for PKG_DEVELOPERs, no otherwise.
#
# CHECK_PORTABILITY_EXPERIMENTAL
#	Enable additional experimental portability checks. New checks
#	may be added without further notice, so expect some packages
#	that previously succeeded to suddenly fail to build.
#
#	Default value: no
#
# Package-settable variables:
#
# CHECK_PORTABILITY_SKIP
#	The filename patterns that should not be checked.
#	Note that a * in a pattern also matches a slash in a pathname.
#
#	Default value: ${REPLACE_BASH}
#	Examples: debian/* test/* *.bash
