#
# This file checks that after installation of a package, all files and
# directories of that package have sensible permissions set.
#
# To use this check in bulk builds, add
#	BULK_PREREQ+= sysutils/checkperms
# to your mk.conf file.
#
# User-settable variables:
#
# CHECK_PERMS
#	Specifies whether the permissions check should be run at all.
#
#	Possible values: yes, no.
#
#	Default value: yes for PKG_DEVELOPER, no otherwise.
#
# Package-settable variables:
#
# CHECK_PERMS_SKIP
#	A list of shell patterns (like man/*) that should be excluded
#	from the check. Note that a * in a pattern also matches a slash
#	in a pathname.
#
#	Default value: empty.
#
# CHECK_PERMS_AUTOFIX
#	If set to yes, any unusual permissions are fixed automatically.
#
#	Possible values: yes, no.
#
