Hello everyone,

I have been very busy working on a lexer and parser for the Eagle SCR
files. (so we can do automatic import of Eagle footprints from the
Farnell website)

It was interesting, in some ways, I know more about Eagle now than I
ever learned using it.

*However, I would like your assistance... *

Can you point me to some of the most extreme/funky or large SCR files
(which define library parts)
so I can stress my parser to the limit.
Funky stuff with relative or polar coordinates, mixing of Mil,Mm and
alike is very welcome to see if my parser breaks.

Also welcome would be an SCR file of the standard Eagle libraries if
someone here knows to find it please point me in the right direction.

Thanks for your assistance, and have a very good day today,
Edwin van den Oetelaar
