Hi Stefan,

when Eagle was used with a metric grid I had to slightly modify 
eagle2exc.pl:

I added

     print OUTFILE "INCH,LZ\n";

right after

     print OUTFILE "M48\n";

and replaced

     while (<INFILE>)
     {
         print OUTFILE $_;
     }

by

     while (<INFILE>)
     {
         if (/^X(\d+)Y(\d+)$/) {
             printf OUTFILE "X%.03fY%.03f\n",$1/1000,$2/1000;
         } else {
             print OUTFILE $_;
         }
     }

to ensure correct fractional numbers.

Some Windows Viewers don't use inch by default and I had problems with 
the files generated by the original version when Eagle wrote files in 
the metric setting.

I'm not perfectly sure this hack is correct, but I hope so. Maybe 
someone with deeper Perl knowledge can comment this.
