Re: NPL to Wireshark compiler/converter

[Tyson Key <tyson.key () gmail com>]

Hi Richard,

That sounds fairly impressive - even if it doesn't do much, right now.

I don't know if you've already seen them; or even if they're helpful, but
have you had a look at
http://nmparsers.codeplex.com/SourceControl/list/changesets for examples of
parser code? (I believe that most files are covered under the BSD Licence,
if the tab on that project microsite is to be believed - so it should be
safe to use them for what you're trying to do (but don't quote me on that)).

I look forward to seeing more, soon...

Tyson.
