After a version by Fredrik Lundh that I found on the web somewhere.
(I like mine better, but of course that may have to do with my alcohol
consumption. :-)

Added some new demos.  Fixed a few others.

pindent.py: use /usr/local/bin/python;
pathfix.py: new script to fix #! lines in a group of scripts.

changed library list somewhat.  CLOSE FILE "tmpconfig.c" AFTER WRITING!

added an output() function to move the I/O out of the algorithm
