         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 analyze 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.

         The  analysis  results  can  be  viewed  with the  Windows 95 /
         Windows NT versions with a tree and list browser. An integrated
         source  code  browser  with  code  colorizing  can  be used  to
         navigate inside the source code by double clicking on function/
         data type names.

         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  HTML  output  files  compatible with  WWW-
         Browsers  like Netscape  Navigator / Communicator  or Microsoft
         Internet Explorer  is supported. It is also possible to produce
         RTF  output files (which can be compiled  for Windows Help) and
         output  for the Rational  Rose CASE tool  as well  as input for
         graph layout programs like Graphlet, VCG, DOT or daVinci.

         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 word processors or
         spreadsheet calculators.

         This  software package  is provided  as  a ZIPped  archive file
         LXTnmm.ZIP  (LISP EXPLORATION TOOLS version  n.mm). The Windows
         version  is named  LXTWnmm.ZIP (LISP EXPLORATION  TOOLS version
         n.mm for Windows). These files only contain the Windows 95 / NT
         versions.  The  versions  for  other  operating  systems  (DOS,


                                        1

         DOS386,  Windows 3.1,  OS/2, LINUX) are  packaged as  add-on in
         separate archives.

         All documentation files are ASCII files and should be printable
         on every printer. The PDF files require Adobe Acrobat Reader.

         For more  information about usage, hardware and software system
         requirements, installation, trademarks, warranties, license and
