Re: Announcing Perl module for parsing APRS packets

[Jeff Laughlin <jeff.laughlin@gmail.com>]

Hi Curt,

Thanks for the suggestion. I wasn't aware that it existed.

After thwarting a few broken links I did manage to find a copy. It
targets perl 4, it's not a module, and it outputs formatted text
instead of a data structure, so it doesn't exactly acheive the same
goals that I have. However it is GPL'ed which is good, so I may be
able to re-use some of it's parsing code without tainting my code. I
still have quite a bit left to implement to have a complete
implementation. And it will certainly be nice to have another GPL code
base to reference other than XASTIR.
