# 20220419 bkw: Modified by SlackBuilds.org, BUILD=3:
# - add -j1 to the 'make install' command. without this, the tcat
#   binary wasn't getting installed.
# - i486 => i586.
# 20220619 tim dickson: updated to 1.0.19. source url and homepage updated, and take over maintainership..
# patched patch, removed rm error messages and fixed script as
# version labling in source is modified. 
#note to self: update patching to sed or similar for next release.
# 20220722 tim dickson: got rm patched added upstream. combined larger patch 
# into easier to maintain patch, and a few sed commands.
