Ezm3 is a simpler, more portable distribution of the Modula-3 compiler and runtime libraries. It is designed for people who would like to install CVSup on their systems as quickly and as painlessly as possible. Ezm3 is derived from the robust and comprehensive PM3 release of Modula-3. Only the components and features which are needed by CVSup were retained. Features which made the package harder to port and install were removed.

The goal of Ezm3 is for you to be able to install Modula-3 on your system in one try, without any patching or false starts.

Ezm3 does not bother trying to support Modula-3's incremental garbage collection feature. This feature is the leading cause of portability and installation problems in other distributions of Modula-3. It does not benefit CVSup, so it has been removed. As a lucky side-effect, removing the incremental GC reduces dynamic memory usage by about 25%.
