+# The darcsver command from the darcsver plugin is needed to initialize the
+# distribution's .version attribute correctly. (It does this either by
+# examining darcs history, or if that fails by reading the
+# zfec/_version.py file). darcsver will also write a new version
+# stamp in zfec/_version.py, with a version number derived from
+# darcs history. Note that the setup.cfg file has an "[aliases]" section
+# which enumerates commands that you might run and specifies that it will run
+# darcsver before each one. If you add different commands (or if I forgot
+# some that are already in use), you may need to add it to setup.cfg and
+# configure it to run darcsver before your command, if you want the version
+# number to be correct when that command runs.
