# This is based on the original SlackBuild from /extra/kde-compat in
# Slackware 13.1

# Adapted for SlackBuilds.org by Niels Horn <email removed>
# - moved building from /opt to $TMP
# - included patch for new libpng (based on work by Stuart Winter)
# Revision date 2012/08/09

# 20180209 bkw: fix download link, pkgs.fedoraproject.org is now toast.

# 20170324 bkw:
# - take over maintenance.
# - i486=>i586.
# - use + rather than ; with find/chmod, speeds things up slightly.
# - minor fix: stripping -jN from MAKEFLAGS failed, if N>9 (or if
#   less than 9, with leading zero(es): -j05 for example).

# TODO: fix these:
