+#
+# DISPLAY
+# $(vcs_status_prompt) : top-level status indicator
+#
+# $(vcs_dirt_status)   : indicator of and count for each type of dirty file
+#                      : simple form can indicate just clean or dirty
+# $(vcs_dirt_age)      : time since last significant action on the work tree
+#                      : helpful for determining staleness of a tree
+# $(vcs_rev_short)     : abbreviated form of current revision
+# $(vcs_rev_long)      : more verbose current revision information
