" This script does more useful indenting for Mako HTML templates. It indents
" inside of control blocks, defs, etc. Note that this indenting style will
" sacrifice readability of the output text for the sake of readability of the
" template.
"
" We'll use HTML indenting globally, python inside <% %> blocks. Inspired by
" the excellent PHP + HTML indentation files such as php.vim by Pim Snel.
"
" Changelog:
" 0.4 - 5 March 2010
" - Added license information
" 0.3 - 15 September 2009
" - Added explicit indenting for ## comments, fixed unindenting count,
" thanks to Mike Lewis (@MikeRLewis) for this
" 0.2 - 15 June 2009
" - Fixed issue where opening and closing mako tags on the same line
" would cause incorrect indenting
" 0.1 - 06 June 2009
" - Initial public release of mako indent file
