Subject: Update update_copyright.py to handle several comment characters.
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=79d10fa69a700c58ef9f35a7f58fcf6830fc6b5e;p=chemdb.git

Update update_copyright.py to handle several comment characters.

Currently extended from '#' to ['#', '%'] to support
  % Copyright
in LaTeX files, but should be flexible enough to handle any character
(or string) by placing the string in the COMMENT_CHARS list.
