About this file
This is a so-called 'frame' file that contains skeleton code for
generating a final Scanner/Parser code.
The '-->TAG' text markers are used to delimit code chunks and typically
correspond to places where additional information is added by the
DFA or ParserGen code.
All information prior to the first 'begin' text marker is discarded.
If the grammar contains a '[copy]' .. '[/copy]' section, its contents
will added instead.
