+ PCCTS - The Purdue Compiler Construction Tool Set
+
+ 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,
+and dlg.
+ 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.
