gEDA-user: My board is back

[Mark Rages <markrages@mlug.missouri.edu>]

I got my board back from advanced circuits.

It looks pretty good, but while enjoying the enclosed popcorn, I noticed
that the TO-220 hole size seems a little small. 0.020" for a pin that is
about 0.060" wide.

I'll just drill out the holes myself and solder both sides, but can we
fix the library?  This is going to be a pain. (25 boards * 5 TO-220
parts * 3 holes per part = a lot of broken drill bits!)  I guess I
should have checked all the hole sizes, but I was in a hurry and figured
TO-220 is popular enough to be well tested.

Has anyone ever seen a TO-220 with pins smaller than 0.020"?

Here is a patch that bumps the size to 0.090 copper, 0.070 hole.  Apply 
to to.inc in the m4 directory:
