QDES Administrative Guide



Steve Clark


The Quick-n-Dirty Editor for STEP (QDES) is prototype editor for STEP product models. QDES is distributed with the NIST PDES Toolkit. This document provides an overview of administrative procedures for QDES. It should be read by anybody who will be responsible for installing, maintaining, or upgrading QDES. Two primary administrative tasks are described: making a new release of QDES, and loading a new conceptual schema into QDES. An administrator is often faced with a more nebulous tasks, as well: namely, to explain curious behavior (bugs or features) encountered by a user. Some aspects of QDES internals, as well as common problems, are described to aid in this tasks. Knowledge of QDES Smalltalk-80 environment, and UNIX are all probably helpful in understanding the issues and procedures discussed.
