+" 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.
+"

+" It's hard to reduce down to the correct sub-set of Perl to highlight in some
+" of these cases so I've taken the safe option of just using perlTop in all of
+" them. If you have any suggestions, please let me know.
