+Command completion
+------------------
+
+BE implements a general framework to make it easy to support command
+completion for arbitrary plugins. In order to support this system,
+all becommands should properly handle the '--complete' commandline
+argument, returning a list of possible completions. For example
+ $ be --commands
+ lists options accepted by be and the names of all available becommands.
+ $ be list --commands
+ lists options accepted by becommand/list
+ $ be list --status --commands
+ lists arguments accepted by the becommand/list --status option
+ $ be show -- --commands
+ lists possible vals for the first positional argument of becommand/show
+This is a lot of information, but command-line completion is really
+convenient for the user. See becommand/list.py and becommand/show.py
+for example implementations. The basic idea is to raise
+ cmdutil.GetCompletions(['list','of','possible','completions'])
+once you've determined what that list should be.
+
+However, command completion is not critcal. The first priority is to
+implement the target functionality, with fancy shell sugar coming
+later. In recognition of this, cmdutil provides the default_complete
+function which ensures that if '--complete' is any one of the
+arguments, options, or option-arguments, GetCompletions will be raised
+with and empty list.
