+" Vim syntax file
+" Language: TeX
+" Maintainer: Charles E. Campbell <NcampObell@SdrPchip.AorgM-NOSPAM>
+" Last Change: Apr 22, 2022
+" Version: 121
+" URL: http://www.drchip.org/astronaut/vim/index.html#SYNTAX_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
+"
+" 6. Please see :help latex-syntax for information on
+" syntax folding :help tex-folding
+" spell checking :help tex-nospell
+" commands and mathzones :help tex-runon
