This is a front-end BBS module (run from within the Terminal server, e.g. as a door) which presents a nice menu from which the sysop may choose external programs that should be setup. The actual install (into the ctrl/xtrn.cnf
file) and “door” setup is performed by the install-xtrn module, but this module makes for a nice sysop-friendly “front-end” (by echicken).
