" NOTE:

" 

" Empty .m files will automatically be presumed as Matlab files

" unless you have the following in your .vimrc:

"

"       let filetype_m="mma"

"

" I also recommend setting the default 'Comment' hilighting to something

" other than the color used for 'Function', since both are plentiful in

" most mathematica files, and they are often the same color (when using 

" background=dark).

"

" Credits:

" o  Original Mathematica syntax version written by

"    Wolfgang Waltenberger <wwalten@ben.tuwien.ac.at>

" o  Some ideas like the CommentStar,CommentTitle were adapted

"    from the Java vim syntax file by Claudio Fleiner.  Thanks!

" o  Everything else written by steve <layland@wolfram.com>

"

" Bugs: 

" o  Vim 6.1 didn't really have support for character classes 

"    of other named character classes.  For example, [\a\d]

"    didn't work.  Therefore, a lot of this code uses explicit

"    character classes instead: [0-9a-zA-Z]
