#  Updated for golly 2.6 -- the source directory structure got changed a bit too!

# 20201112 bkw: update for v4.0. Which adds a python3 dep.
# 20181211 bkw:
# - Take over maintenance.
# - i486 => i586.
# - Upgrade for v3.2.
# - Switch from wxPython (2.x) to wxGTK3. It's possible to build with
#   either version of wx, but for v3.2, the grid in the UI doesn't display
#   if you build with wxPython. Someone with more wx experience than me
#   is invited to investigate why this happens...
# - Minor simplifications and cleanups.
