" Vim syntax file
" Language : TeX
" Maintainer : Dr. Charles E. Campbell, Jr. <Charles.Campbell@gsfc.nasa.gov>
" Last change: August 21, 1998
"
" Notes:
" 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)
" Removes any old syntax stuff hanging around
