+Submitted By: Ken Moffat <ken at linuxfromscratch dot org>
+Date: 2016-06-11
+Initial Package Version: 2.13
+Upstream Status: Version is historic and unmaintained.
+Origin: Found at fedora, plus fixes for LFS.
+Description: All of the patches currently used by fedora, except for
+the patch which ensures gawk is used in preference to mawk (we do not
+install mawk).  For LFS: we put mktemp in /usr/bin not /bin, remove
+the install-info target because that will overwrite standards.info
+with an old version (fedora always use a DESTDIR), and change the
+man and info dirs to ${datadir}/ i.e. /usr/share (an empty /usr/info
+will otherwise be created).

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description. Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in. You must
+# make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':'.
