NAME
       ml-ulex - a Unicode-compatible lexical analyser generator for Standard
       ML

SYNOPSIS
       ml-ulex [OPTIONS] file

DESCRIPTION
       ML-Ulex is a lexer generator that supports Unicode characters (in UTF-8
       representation) and an extended form of regular expressions.

OPTIONS
       -32
           run the 32-bit version of the program (currently the default).

       -64
           run the 64-bit version of the program.  This option only applies to
           the x86-64 (aka amd64) architecture.

       --dot
           generate DOT output ( <http://www.graphviz.org>).  The generated
           file will be named file.dot, where file is the input file.

       --match
           enter interactive matching mode.  This will allow interactive
           testing of the machine; presently, only the INITIAL start state is
           available for testing (see the User Guide
           <http://www.smlnj.org/doc/ml-lpt/manual.pdf> for details on start
           states).

       --ml-lex-mode
           operate in ml-lex compatibility mode.

       --table-based
           generate a table-based lexer.

       --fn-based
           generate a lexer that represents states as functions and
           transitions as tail calls.

       --minimize
           generate a minimal machine.  Note that this is slow, and is almost
           never necessary.

       --strict-sml
           generate strict SML (i.e., do not use SML/NJ extensions).  This
           flag is useful if you want to use the output with a different SML
           system.
