" Vim syntax file
" Language:    Mason (Perl embedded in HTML)
" Maintainer:  Andrew Smith <andrewdsmith@yahoo.com>
" Last change: 2003 May 11
" URL:	       http://www.masonhq.com/editors/mason.vim
"
" This seems to work satisfactorily with html.vim and perl.vim for version 5.5.
" Please mail any fixes or improvements to the above address. Things that need
" doing include:
"
"  - Add match for component names in <& &> blocks.
"  - Add match for component names in <%def> and <%method> block delimiters.
"  - Fix <%text> blocks to show HTML tags but ignore Mason tags.
"

" Clear previous syntax settings unless this is v6 or above, in which case just
" exit without doing anything.
