---------

There were not all keywords or reserved words. I made a basis for adding
and removing those words. Fonts are also easily changed. Parsing was
really an interesting challenge .. I end up solution which .. expect that
user doesnotwriteeverythingtogether. If Emacs gets too slow .. comment out
some parts. I hope somebody will be interested of this stuff.
