notes on debian packaging

The pristine source was changed somewhat.
The document file  CP-bib.ps was added to the source tree.  This modified
source tree is distributed as circlepack_4.0.1.orig.tar.gz

would not work with
ii  gcc             2.7.2.3-4.8 
this makes an executable which hangs

this seems to work fine.
ii  egcc            2.90.29-0.6

-O2 produced broken code that freezes.


The name of the executable is circlepack .
The help file was moved to /usr/lib/circlepack and the code was modified 
in accordance.
