# 20240122 bkw: switch to roblillack's fork, v0.2.6+20220428_38b38a6.
# Get rid of old patches (no longer needed), and add a new patch to
# give the window a working close button.
# 20230708 bkw: BUILD=3, install to the same Applications dir as
# windowmaker's WPrefs.app (and no creating /usr/GNUstep, which was
# never a good idea).
# 20210825 bkw: fix build on -current, BUILD=2.
