This directory contains a makefile, perl script, and templates for creating
an Xcircuit library of all the 74xx DIP parts.  The files are:

-rwxr--r--    1 bryce    tlw         76255 Feb 15 15:51 TTL_74xx_DIL.m4

-rwxr-xr-x    1 bryce    tlw          3946 Feb 15 17:36 make-dip-lib.pl

TTL_74xx_DIL.m4 comes from the PCB for linux distribution, and it 
specifies the pinout for all the 74xx parts.  PCB for linux is available
from http://bach.ece.jhu.edu/~haceaton/pcb/ and distributed under the
GPL.

Diptemplate.lps is an Xcircuit library with templates for 8-pin, 14-pin,
16-pin, 20-pin, 24-pin, and 28-pin DIPs.  To change the appearance of
all the diplib outputs, just edit the templates and run make again.
The pin labels should be called "pinN" and there should be four title
labels containing title1-title4.  You can move everything around, but
these strings must stay the same so that the perl script can find them.

make-dip-lib.pl is a perl script which reads the TTL_74xx_DIL.m4 file
and the diptemplate.lps and spits out several xcircuit libraries
containing symbols for different DIPs, with pinout and label.

Makefile just runs the perl script with the right arguments.
