# 20230506 Jorge: upstream (since v2.0) supports GNU readline:
# - removing static linking with libedit.

# 20230424 bkw: modified by B. Watson, at the maintainer's request. There is
# an issue with modern libedit that I've temporarily fixed by including an
# older static libedit in this build. libedit upstream has already fixed the
# issue and it will be in their next release, but for Slackware 15.0 we won't
# ever get an updated libedit unless it has an actual security issue.
# Also:
# - updated for v1.19.
# - removed useless INSTALL from package.
# - add doinst and douninst to rebuild /usr/info/dir.
# - simplify the build commands a bit.
# - fix the bas55.info file so it works correctly.
