# This file checks that after installation, all files of the package
# that start with a "#!" line will find their interpreter. Files that
# have a "#!" line with a non-existent interpreter will generate an
# error message if they are executable, and a warning message otherwise.
#
# The following variables may be set by the pkgsrc user in mk.conf:
#
# CHECK_INTERPRETER: YesNo (default: no)
# Whether this check should be enabled or not.
#
# The following variables may be set by a package:
#
# CHECK_INTERPRETER_SKIP: List of paths or paths with wildcards
# (default: empty)
# (example: share/package1/* share/package2/somefile)
# The list of files that are skipped when running the check.
# Additionally, all files in share/examples and share/doc are
# skipped as well.
