ERRATA FOR THE ABOVE LIBRARY: the 12 pin SIL pattern is not centered on the origin. Not big deal, so I won't reupload it.
Here's another version of the library. I designed this for doing toner transfer PCBs. It has slightly bigger holes that fit a 0.9mm drill and the pad itself is bigger. When doing toner transfer boards, either use big clearances or get some soldermask like
this. And do something like this

I haven't done this, but soldermask is relatively cheap, so I want to give it a try. I still can't even get 10 mil tracks with 12 mil clearances, they claim they can do 6 mil tracks and 8 mil clearances at home!
I have only attached the patterns because the symbols are the same. There is an option on DipTrace's schematic capture program for choosing a different pattern.
