# 20260703 bkw:
# - take over maintenance.
# - update for v0.8.1. the previous version (0.7.8) segfaults on startup,
#   on Slackware 15.0.
# - add REQUIRES=libdockapp since 0.8.1 needs it.
# - fix ARCH typo, i465 => i586.
# - add SMP=no option (unlikely to ever be used...)
# - replace README and slack-desc with text from upstream's README.md.

# version 1.0 - 2020/03/29
# - initial creation
