how do i wrote parser?

I have a pretty good educational understanding of computer grammar theory, so I get the concepts behind parsers and context-free grammars, but I've never actually implemented a parser.  And now I need to write one.

Specifically, I'm looking to write a loader for .md5mesh files (they are text format).  Let's say I'm able to get a grammar for it written on paper that matches that file format's general structure.  Where do I start in code?  This is fortunately not as complicated as a programming language's language, since it's a format that's about data and not code, but it's still a somewhat more complicated 3D format than, say, the Alias Wavefront .obj format (where reading and parsing is as simple as a for loop and sscanf -- but that format doesn't support skeletal animation and other things the way .md5mesh does).

Implement an FSM by hand.

Also, peg/leg or bison/flex will both be much better than trying to use regexen.
