NAME
quintuslgt - Logtalk integration script for Quintus Prolog

SYNOPSIS
quintuslgt

DESCRIPTION
quintuslgt is a Logtalk integration script for Quintus Prolog. It automatically loads the Quintus Prolog adapter file, the Logtalk compiler and runtime, the Logtalk default table of library names and paths, and any existing settings file found on the lookup directories. It uses the prolog executable +l option to load the Logtalk files. It passes any options to the prolog executable; see the Quintus Prolog documentation for the available options.
