# Public targets for developers:
#
# changes-entry-noupdate:
#	Appends a correctly-formatted entry to the pkgsrc CHANGES file.
#	The CHANGES file is presumed to be up to date and writable.
#	Note that the first assumption is often wrong and that the
#	second is wrong for those that set CVSREAD.
#
#	Command-line variables:
#
#	CTYPE
#		The type of entry to add. Must be one of "Added",
#		"Updated", "Renamed", "Moved", or "Removed".
#		The default is "Updated".
#
#	TO
#		When a package is renamed, this is the new name of the
#		package.
#
#	NETBSD_LOGIN_NAME
#		The login name assigned by the NetBSD Project.
#		The default is the local login name.
#
#	PKGSRC_CHANGES
#		The path to the CHANGES file to which the entry
#		is appended.
#		The default is ${PKGSRCDIR}/doc/CHANGES-YYYY.
#
#	Example usage:
#		% cd /usr/pkgsrc/category/package
#		% make changes-entry CTYPE=Added
#
# changes-entry:
#	Like changes-entry-noupdate, plus the CHANGES file is updated,
#	and if not writable, "cvs edit" is done.
#
# commit-changes-entry cce:
#	Like changes-entry, plus the CHANGES file is committed.
