a distfile or a pkgsrc patch. It's simple, cleaner, less magic, etc. (duh!). While here, I notice that _CHECKSUM_CMD was already being defined in mk/checksum/checksum.mk (as it should be), so update the definition from mk/patch/patch.mk and remove it from patch.mk.

# NAME
|
|
# checksum -- checksum files
|
|
#
|
|
# SYNOPSIS
|
|
# checksum [options] distinfo [file ...]
|
|
#
|
|
# DESCRIPTION
|
|
# checksum will verify the checksums in the distinfo file for each
|
|
# of the files specified.
|
|
#
|
|
# The checksum utility exits with one of the following values:
|
|
#
|
|
# 0 All of the file checksums verify.
|
|
#
|
|
# 1 At least one of the file checksums did not match.
|
|
#
|
|
# 2 At least one of the files is missing any checksum.
|
|
#
|
|
# >2 An error occurred.
|
|
#
|
|
# OPTIONS
|
|
# -a algorithm Only verify checksums for the specified algorithm.
|
|
#
|
|
# -p The specified files are patches, so strip out any
|
|
# lines containing NetBSD RCS ID tags before
|
|
# computing the checksums for verification.
|
|
#
|
|
# -s suffix Strip the specified suffix from the file names
|
|
# when searching for the checksum.
|
|
