This file is the GAP SCSCP server configuration file on Fedora systems: it loads all necessary packages, reads all needed code, installs all procedures which will be exposed to the client and finally starts the SCSCP server itself.


/etc/scscp/gap/configpar.g These files set the default parameters needed by the GAP SCSCP package; they are fully commented.


This directory is the default location on Fedora systems for all systemwide configuration material needed by the GAP SCSCP server and any GAP SCSCP client.
