In GAP 4.7.2 this is documented in "3.2-3 Configuring User preferences" (enter `?WriteGapIniFile' in GAP to see that section). You may call WriteGapIniFile(); to create gap.ini file where you may specify user preferences. Its output will tell the path to this file, then you may edit it around the lines ## A list of names of packages which should be loaded during startup. For ## backwards compatibility, the default lists most of packages that were ## autoloaded in GAP 4.4 (add or remove packages as you like). # SetUserPreference( "PackagesToLoad", [ "autpgrp", "alnuth", "crisp", "ctbllib", "factint", "fga", "irredsol", "laguna", "polenta", "polycyclic", "resclasses", "sophus", "tomlib" ] ); uncommenting the last command and modifying its argument, adding packages you want to load in addition to those already listed there.
