Introduction

Ulm's Modula-2 System is a software development environment for Modula-2 which runs on several UNIX systems. The system consists of

• a compiler which is derived from the 4-pass Lilith Modula-2 compiler of the ETH Zürich and conforms to [PIM3],
• a library which interfaces UNIX system-calls and provides system-independent abstractions for input and output processing and ASCII-terminal based windowing systems,
• a set of tools for generating and updating makefiles, debugging, and profiling,
• and documentation in the form of manual pages and this document.

All sources are freely available. The parts of the compiler which are derived from sources of the ETH Zürich are distributed separately and require a written agreement with us (but no license fee). All other sources are part of the main package and may be used and distributed under the terms of the GNU General Public License (version 2).

The SPARC-specific implementation of the library module MathLib has been partially derived from the GNU C Library and includes software developed by the University of California, Berkeley and its contributors.
