[aprssig] APRS-IS perl client

[James Washer]

I don't think you'll find a BNF... The standard is way too loose, or, at least, the implementation is too loose.

I've got perl that will parse just about everything, but it is a very strict interpretation and rejects lots of packets that (I feel) violate the spec. N5FTL-1>APRS,KE5PL-4*,TRACE5-4,qAR,K5WTC-10:WIDEn-n APRS Digipeater Sterling City, 

For example, I consider these to be bad/illegal packets.. easily fixed with s/:/:>/ but bad as they stand.
