Installation Notes for Windows NT/2000/XP
                 =========================================


CDuce can be executed on Microsoft Windows by using the
RedHat/Cygnus environment Cygwin freely available at

http://www.cygwin.com/

The executable needs the cygwin1.dll that is distributed 
under GPL license. This is not compatible with the CDuce license.
For this reason we do not provide binaries but give here detailed 
instructions about how to compile CDuce sources under Cygwin/Windows.


------------------------------------------------------------------------------
Prerequisites
------------------------------------------------------------------------------

Before compiling CDuce on Windows, you need to install recent 
releases of the following packages:


cygwin
  http://www.cygwin.com
ocaml      
  http://caml.inria.fr/ocaml/distrib.html
findlib    
  http://www.ocaml-programming.de/packages
wlex       
  http://www.eleves.ens.fr/home/frisch/soft.html#wlex
pcre-ocaml 
  http://www.ai.univie.ac.at/~markus/home/ocaml_sources.html
ocamlnet   
  http://sourceforge.net/projects/ocamlnet
pxp

Installation notes (you are advised to follow this order):

1) Download and execute cygwin setup.exe.
   - Choose Internet installation
   - Choose a root directory whose path has no blanks in it
   - Choose as Local Package Directory <your root>/usr/src (optional)
   - Choose the mirror closest to you
   - When asked to select the packages to install add to the default
     choices the following packages:
       Devel/
         autoconf*
         automake*
         binutils
         gcc*
         make
         patchutils
       Lib/
	 libpcre
         pcre **both binaries and sources**
     you may also find useful to install the following packages
       Editors/
         emacs or vim (no trolls)
       Net/
         openssh
         ncftp
       Devel/
         cvs
       Utils/
         diff
         patch
     then proceed with installation


2) Download (we suggest in /usr/src) and install Ocaml
   [For the impatients: ./configure && make world.opt && make install]


3) Download (guess where) and install findlib
   a plain ./configure && make all && make opt && make install
   should work 


4) Download and install ulex 


5) Download and install pcre-ocaml. 

   
6) Download and install ocamlnet


7) PXP:
   CDuce requires a development version >= 1.1.93.


Now you can compile CDuce sources as indicated in the INSTALL file 
namely
