Merr is a syntax error message table generator that works with YACC and related LR-parser generators such as byacc and bison. Merr was developed in support of the Unicon programming language implementation. It is now available as a standalone tool for use in compiler writing and compiler instruction. At present Merr supports parsers generated for the C/C++ and Icon/Unicon programming languages; the author is happy to assist people interested in porting Merr for use with other LR parser generator systems, target languages, and machine platforms.
