# Slackware build script for jbigkit
# Written by Iskar Enev
# Modified and now maintained by B. Watson <urchlay@slackware.uk>
# Original version had no license. Modified version is licensed under
# the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# 20260712 bkw, BUILD=3:
# - take over maintenance.
# - remove static libs (except for libjbig85.a since there's no shared one).
# Took this over as it's an optional dep for GraphicsMagick.

# 20220418 bkw: Modified by SlackBuilds.org, BUILD=2:
# - strip binaries and libraries.
# - rename INSTALL in doc dir (it's not useless; shut sbopkglint up).
