#
# User Interface that generates custom QFP and SOIC packages for pcb-1.6.3
# Invoked from a line like
# esyscmd(qfp-ui $1 $2 $3)
# within an m4 macro triggered by pcb-1.6.3
# depends on having the Right [TM] m4 macro PKG_QFP in qfp.inc
# Copyright 1999 Larry Doolittle <LRDoolittle@lbl.gov>
#
# SOIC support added Jan 2000 Larry Doolittle
# Use nX==0 for that mode.
#
# Parts library added Feb 2000 Larry Doolittle
# That feature is still rough, but it is useful, and you get the idea
#
# Refinement of library file usage Mar 2000 Larry Doolittle
# Peeks at the X resource Pcb.libraryPath, uses that for a search path
# for qfp.dat. Appends .:$HOME to that path, and writes any updates
# (via the "Save" button) to $HOME/qfp.dat only.
#
# Wish list:
# have someone else test it enough to know what needs fixing
# proper support for changing pin 1 location
# more choices of outline (at least inboard vs. outboard)
# more packages in default qfp.dat, double checked and tested
