" Vim syntax file
" Language:	TeX

" 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
