This batch file
calls
papco_startup.pro, but it calls the papco_configure widget (see
Section 3.5) first and then calls a program which rewrites
papco_startup.pro and papco_include_modules.pro accordingly. Use
this file to ``configure'' PaPCo or to load up previous PaPCo
configurations, use papco_startup.pro to run the latest previous
configuration of PaPCo.
