" Vim syntax file
" Language: TeX
" Maintainer: Dr. Charles E. Campbell, Jr. <NdrchipO@ScampbellPfamily.AbizM>
" Last Change: Feb 27, 2007
" Version: 37
" URL: http://mysite.verizon.net/astronaut/vim/index.html#vimlinks_syntax
"
" Notes: {{{1
"
" 1. If you have a \begin{verbatim} that appears to overrun its boundaries,
" use %stopzone.
"
" 2. Run-on equations ($..$ and $$..$$, particularly) can also be stopped
" by suitable use of %stopzone.
"
" 3. If you have a slow computer, you may wish to modify
"
" syn sync maxlines=200
" syn sync minlines=50
"
" to values that are more to your liking.
"
" 4. There is no match-syncing for $...$ and $$...$$; hence large
" equation blocks constructed that way may exhibit syncing problems.
" (there's no difference between begin/end patterns)
"
" 5. If you have the variable "g:tex_no_error" defined then none of the
" lexical error-checking will be done.
"
" ie. let g:tex_no_error=1
