# 20230516 bkw: *finally* updated after almost 6 years. upstream moved
# to github but didn't update or remove the old website...
# - updated for latest git (0.15+2857fc3_20180311). used latest git
#   rather than the last release because there's a critical bugfix:
#   release was missing the LSR zeropage opcode.
# - use upstream's man page, now that there is one. though I had to
#   patch it to add a couple options that aren't mentioned there.
# - get rid of no-longer-needed compilefix and helpformat patches.
# - mention the predefs files in README.
