Re: gEDA-user: PCB: Converting M4 to new Footprint?

[John Luciani <jcljr58@yahoo.com>]

The main portion of the script was taken from the
"Troubleshooting Old Style Libraries" section of 
the pcb.html that should be in the doc subdirectory
of your PCB installation.

If you change the line 

  PCB_M4_DIR=/local/pub/pcb-20040215/share/pcb/m4

to reflect your M4 path the script should run in any 
directory.

The double quotes ensure that a string is passed
to the echo command. The awk command line just removes
blank lines.

If you run this script and get a line that only
contains the string that was piped to m4 it usually
means that the package name you were looking
for was not found. If this happens look in the files
that common.m4 includes.

Check the "Library Creation" section of pcb.html for
more information.
