How to install this: 1) Follow the directions for "MAKING YOUR OWN SYNTAX FILES" in: http://vimdoc.sourceforge.net/htmldoc/syntax.html#mysyntaxfile These instructions essentially say to copy the syntax file (jam_mr.vim) to $(HOME)/.vim/syntax if you're on Unix. If you're not, do what the document suggests. 2) Let vim know how to identify Jam files. General info on how to identify files is here: http://vimdoc.sourceforge.net/htmldoc/filetype.html#new-filetype Here's the command which I put in my $(HOME)/.vim/filetype.vim file: " Jam/MR au BufNewFile,BufRead [Jj]amfile,Jamrules,Jambase setf jam_mr This works under Vim 6.0 and I would expect it to work under other versions. Happy Jamming! -Chris
