" Bugs
" - in the appropriate sections keywords are always highlighted
"   even if they are not used with the appropriate meaning;
"   example: in
"       MODEL demonstration
"       TYPE
"      *area AS area
"   both "area" are highlighted as spupType.
"
" If you encounter problems or have questions or suggestions, mail me

" Remove old syntax stuff
" For version 5.x: Clear all syntax items
" For version 6.x: Quit when a syntax file was already loaded
