""" Implementations for various useful completers
See extensions/ipy_stock_completers.py on examples of how to enable a completer,
but the basic idea is to do:
ip.set_hook('complete_command', svn_completer, str_key = 'svn')
NOTE: some of the completers that used to be here, the ones used always by
default (loaded before by ipy_stock_completers) have been moved into
core.completerlib, where they will be further cleaned up and maintained. The
rest of this file would need to be well commented, cleaned up and tested for
inclusion into the core.
