A Unix variant that was used on Apollo workstations before Apollo was bought by Hewlett Packard. AEGIS has some advantages over standard BSD or System V Unix. It includes faster file access and a richer command set; there are commands to find out which process is running on a particular node, which process is locking a particular file, etc.


A CASE tool for project change management written by Peter Miller, with minor contributions by a few others. Aegis is licensed using the GNU GPL but is not a GNU project.
