" URL: http://lingewoud.nl/downloads.php

" - fixed wrong indention when a php-tag is opened and closed on
" one single line.
" 0.2 - 23 feb 2004
" - applied patch from Holger Dzeik <dzeik@nentec.de>
" - added changelog
" - added default indention of 3 spaces after the <?php for better
" reading
" - replaced URL
" - reformatted the options section
" 0.1 - 27 mar 2003
" - initial creation of html-enhanced php indent-file
" Options:
let php_noindent_switch=0 " set this to '1' to not try to indent switch/case statements
set sw=3 " default shiftwidth of 3 spaces

finish
endif
