Detailed Description

Author:: Wolfgang Wieser ] wwieser (a) gmx <*> de [

This is meant to provide some object-oriented glue for re-entrant flex(1)-based scanners.

The design here is semi-clean in that you need to #include files into your flex file but unfortunately we cannot get around the code duplication.

You can have several re-entrant flex scanner (which differ in the underlaying grammar) in one application but in this case you MUST supply differnet name prefixes using option prefix="BLAH" AND supply the same prefix with the FLEX_PREFIX define. flex(1) will then put this prefix at the beginning of all exported symbols and hence the different scanners will not collide at link time. However, that same reason requires that we include the basically same class code into each flex file separately. The files included just "look" the same but the ARE actually NOT the same after expanding all the flex-based macros used in them.

Well, sign, staying reasonable, we cannot change that...
