From: W. Trevor King Date: Tue, 1 Jun 2010 17:36:42 +0000 (-0400) Subject: Convert update_copyright.py to a more VCS-agnostic version. X-Git-Tag: v0.2~18^2~5 X-Git-Url: http://git.tremily.us/?p=update-copyright.git;a=commitdiff_plain;h=76a0aea0d5dcbd7ce2eba5e8355d86ed2c4c5b4a Convert update_copyright.py to a more VCS-agnostic version. This will make it easier for others to grab this code for their own projects. Currently supported VCSs: Git, Mercurial, Bazaar. --- diff --git a/update_copyright.py b/update_copyright.py index 37f4ba5..ea8908e 100755 --- a/update_copyright.py +++ b/update_copyright.py @@ -30,13 +30,9 @@ import email.utils import os import os.path import re -import StringIO import sys import time -import mercurial -import mercurial.dispatch - PROJECT_INFO = { 'project': 'Hooke', @@ -65,6 +61,15 @@ License along with %(project)s.
