its not too hard :) you should be able to get the general gist of flex/bison 
(lex/yacc) from various examples floating around. there's some pretty good 
documentation and tutorials. if worse comes to worse, you could get the 
o'reilly book on lex/yacc (which applies to flex bison as well).

of course, the best parser product around is probably antlr. its written in 
java but can generate C++ lexers and parsers. you just have to link against 
the resultant library. IIRC the antlr parser comes with a java grammar as an 
example. it might even come with a C# example - if, god forbid :) you want to 
offer a C# filter. hehe.
