+# 20170224 bkw:
+# - BUILD=2
+# - install /etc/wmmonrc as a proper .new config
+# - make doinst.sh treat /etc/wmmonrc.new correctly
+# - don't install INSTALL in package docdir
+# - added notes (to myself) about version numbers, to stop myself
+#   from trying to "upgrade" to 1.2b1.
+# - actually mention windowmaker in the README (derp!)
+
+# Notes about versions:
+
+# The version number is from Debian. I don't know why they called it 1.1,
+# because:
+#   $ wmmon -v
+#   WMMon version 1.2.b2
+# Since I'm using their tarball, I'll stick with their version numbering.
+
+# http://www.dockapps.net/wmmon has a wmmon-1.2b1 release, which looks
+# like a higher version number than we use for VERSION here. However
+# it's really older (missing some options/bugfixes) and this is obvious
+# if you look at the output of wmmon -v (1.2.b1 < 1.2.b2).
+
+# I could package up a newer git commit (there are commits from 2015),
+# but they add complexity (a new libdockapp.so library, as a separate
+# source tree, which wmmon would require as a dependency) and don't fix
+# any bugs or add any features beyond what we've got here. Plus, we've
+# got the same version Debian uses, and Fedora uses effectively the
+# same version too (they include a commit "Remove trailing whitespace"
+# that doesn't change the actual code). Gentoo uses 1.2b1, but I'm not
+# using them for a role model :)
