7 " Remarks: - Now includes R syntax highlighting in the appropriate
8 " sections if an r.vim file is in the same directory or in the
9 " default debian location.
10 " - There is no Latex markup in equations
11 " - Thanks to Will Gray for finding and fixing a bug
12 " - No support for \if, \ifelse and \out as I don't understand
13 " them and have no examples at hand (help welcome).
14 " - No support for \var tag within quoted string (dito)
16 " Version Clears: {{{1
17 " For version 5.x: Clear all syntax items
