Catalog of Free Compilers and Interpreters
This list catalogs freely available software for language tools, which includes the following: compilers, compiler generators, interpreters, translators, important libraries, assemblers, etc. -- things whose user interface is a language. Natural language processing tools may also be included.
This list is primarily aimed at developers rather than researchers, and consists mainly of citations for production quality systems. There is some overlap of coverage between this document and other lists and catalogs.
