        Welcome to LXT - the LISP EXPLORATION TOOLS!

        The LISP Function Tree Generator  (LFT)  is  a  powerful  program
        development,  maintenance and documentation tool. It provides the
        programmer the ability to analyse the LISP or SCHEME source  code
        of  applications,  no matter how big or complex they are.  LFT is
        very useful to explore  new,  unknown  software  and  to  support
        software reuse and maintenance.

        By scanning and analyzing the program source code,  LFT builds an
        internal representation of the function call hierarchy relations.
        The analysis is done with the original source code, no additional
        editing to mark functions or data types in  the  source  code  is
        necessary.  Several  features  and  options  allow  the  user  to
        customize the generated hierarchy tree chart output and to get  a
        large set of useful information about the source code.

        An  important feature is the database generation which allows the
        recalling of information without reprocessing  the  source.  This
        database  can again be read from LFT to produce different outputs
        or to add new files to the database. The database format is dBASE
        compatible.  A special recall program  called  LFTN  allows  fast
        searching  for  items  in the database.  This program can be used
        within any environment,  for example  from  inside  editors  like
        BRIEF,  QEDIT or MicroEMACS (DOS and WINDOWS version), to provide
        a full software project management  system  with  access  to  all
        functions  and  data  types  with just a keystroke.  This feature
        makes a comfortable "hypertext source code browser  and  locator"
        system  out  of  the  editor.  The  windows  version  provides an
        additionally DLL for database access.

        The generation of output files compatible with HTML viewers  like
        NCSA Mosaic,  Netscape or WinWord Internet Assistant is possible.
        Also RTF output files which can be compiled for Windows Help  and
        output for the Rational Rose CASE tool is possible.

        Another  feature is the calculation of the critical function call
        path.  It is possible to generate formatted ASCII text files with
        lists of the functions and the scanned files which can be used as
        input  for  other  programs  like  wordprocessors  or spreadsheet
        calculators.

        This  software  package  is  provided  either  as  a   compressed
        self-extracting  archive  file LXTnmm.EXE (LISP EXPLORATION TOOLS
        version n.mm) or as a ZIPped archive file LXTnmm.ZIP. The Windows
        versions are named LXTWnmm.EXE (LISP  EXPLORATION  TOOLS  version
        n.mm for Windows) or LXTWnmm.ZIP.
