Eagle compatibility: save in old version format

Yes, export the lib, sch, and brd as script and then run the scripts on 
the 4.11 version. Normally it works without problems, or with minor 
problems, but normally the workaround to place the component in the 
schematic is less time then adjusting the script. I don´t find the 
german thread on that i have explained the procedure, but the problems 
seems, that on the 5x version, the required ulp is missing, just use 
that of the 4.x version.

Beitrag "Re: Eagle 5.2-Schaltplan fuer v4.16 speichern?" This is the thread 
and
the message explaining the procedure, use babelfish translator.

If you have problems on making the conversion, write, or send me the 
files to smt.mounter@gmail.com without the 1st dot.

I send you the files. I really don't understand the other thread- and 
it's not because of the language :-( Isn't there any official 
documentation from Cadsoft on how to do it? Eagle is a mess...
