+" 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
+
