# This file contains functions that are used by the various awk
# programs that check things in pkgsrc. All these programs must be
# called with the following environment variables set:
#
# CK_FNAME
#	The name of the file that is checked. Since awk interprets
#	command line arguments in a weird way, the input file must be
#	passed via stdin.
#
# CK_PROGNAME
#	The program name to be used in diagnostic messages.
