21'''workspace extensions for mercurial
22
23This extension contains a number of commands to help you work within
24the OpenSolaris consolidations.
25
26Common uses:
27
28Show diffs relative to parent workspace			- pdiffs
29Check source style rules				- nits
30Run pre-putback checks					- pbchk
31Collapse all your changes into a single changeset	- recommit'''
32

34#
35# NB: This assumes the normal directory structure, with this
36#     extension 2 levels below .../lib/python.
