tcLex is a lexer (lexical analyzer) generator
extension to Tcl. It is inspired by Unix and GNU lex
and flex, which are "tools for generating programs
that perform pattern-matching on text". It is very
similar to these programs, except it uses Tcl
philosophy and syntax, whereas the others use
their own syntax, and are used in conjunction with
the C language. People used to lex or flex should
then feel familiar with tcLex.
