+# Some parts of this completion's behaviour are configurable:
+#
+# Say, you got your own git sub-commands (git will run a program `git-foo'
+# when you run "git foo") and you want "git f<tab>" to complete that sub
+# commands name for you. You can make that sub-command know to the completion
+# via the user-command style:
+#
+#     % zstyle ':completion:*:*:git:*' user-commands foo:'description for foo'
+#
+# `user-commands' is a list style, so you can add any number of programs there.
+# The :description part is optional, so you could add all git-* programs from
+# your $path like this:
+#
+#     % zstyle ':completion:*:*:git:*' user-commands ${${(M)${(k)commands}:#git-*}/git-/}
+#
+# You could even create a function _git-foo() to handle specific completion
+# for that command.
+
+# TODO: There is still undocumented configurability in here.
+
 # TODO: All if (( words[(I)-option] )) should be turned into
 # if (( words[(I)-option] > 0 && words[(I)-option] < CURRENT )), as the user
 # may go back and want to add an option before -option and in that case should
