# 20231229 ALe: BUILD=3
# Imported Debian patches to support -fPIC option, improved timestamps.
# Added fpc source code with option to exclude it.

# 20230814 ALe: BUILD=2
# - tested conflict with ptop: it no longer exists because in ptop SlackBuild
#   the name /usr/bin/ptop.py is now being used.

# 20230520 bkw: ARCH is now i586, use separate SRCARCH for the i386
# in the source filenames. I severely doubt this would run on a 386
# anyway. i586 is the minimum *Slackware supported* ARCH this will run
# on. Not bumping BUILD because the package contents don't change.

# 20220415 bkw: BUILD=2
# - remove *.rsj files from /usr/bin.

# 20210904 bkw:
# - take over maintenance.
# - update for v3.2.2.
# - install the IDE's data files to fpc base dir, not /usr/bin (ugh).
# - include man page for instantfpc/ifpc.
# - TODO: find out why exiting fp (the IDE) leaves the cursor blinking.
#   It's *very* annoying but not a showstopper.
