# Slackware build script for fujinet-pc

# Written by B. Watson (urchlay@slackware.uk)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# 20260203 bkw, BUILD=2:
# - expand shell script wrapper a bit, and use a symlink for the data/ dir
#   rather than copying it. should make upgrades closer to seamless.
# - add a few more TNFS hosts to the default config.
# - update man page.

# 20260125 bkw:
# - updated for v1.5.2 (which would be 25.12.x by the old version scheme).
# - upstream folded the fujinet-pc fork back into the main fujinet-firmware
#   repo, so we get a new homepage and differently-named tarball.

# 20260117 bkw: updated for v2312.2.
