Description:

PCCTS is a set of public domain software tools designed to facilitate
the implementation of compilers and other translation systems. These
tools currently include antlr, dlg and support code. In many ways,
PCCTS is similar to a highly integrated version of YACC [Joh78] and
LEX [Les75]; where antlr (ANother Tool for Language Recognition)
corresponds to YACC and dlg (DFA-based Lexical analyzer Generator)
functions like LEX. However, PCCTS has many additional features which
make it easier to use for a wider range of translation problems.
