THE HUGIN LITE DISTRIBUTION
---------------------------

    This package contains demonstration versions of the Hugin Explorer
    and the APIs for the Hugin Decision Engine.

    The demonstration versions are limited to handling networks of up
    to 50 states, and the learning algorithms are limited to 500 cases.


SYSTEM REQUIREMENTS
-------------------

    Solaris: UltraSPARC Solaris 10, x86/x64 Solaris 10.
    Linux: Red Hat Enterprise Linux 4 (and compatible distributions).

    Sun Java SE v5.0 or v6 is required for the Hugin GUI application
    (but the Hugin Java API also works with v1.4.2).  This can be
    downloaded from <http://java.sun.com/javase/downloads/> -- be sure
    to get the 32-bit version of the Java software.


INSTALLATION
------------

    This software distribution consists of a single directory,
    HUGIN_LITE.<platform>, containing all files necessary to use the
    Hugin software.  When you unpacked the distribution, you created
    this directory.  The README file you are currently reading is
    placed in this directory.


 1. Installing the files.  A common choice is to install in /usr/local.
    Assuming there is no HUGIN_LITE.<platform> directory in /usr/local,
    unpack the distribution tar-file there.

	% cd /usr/local
	% gunzip -c HUGIN_LITE.<platform>.tar.gz | tar xvf -

    You may want to rename the HUGIN_LITE.<platform> directory.  A common
    choice is to name it "hugin".  Assuming there is no file or directory
    in /usr/local named "hugin":

	% mv HUGIN_LITE.<platform> hugin


 2. Define the environment variable HUGINHOME.

    In order to use this software, you must tell it where to find the
    help files.  You do this by setting the HUGINHOME environment variable
    in your shell startup file.

    If you are using the C-shell, insert the following line in the
    ".cshrc" file in your home directory.

	setenv HUGINHOME /usr/local/hugin

    (assuming /usr/local/hugin were chosen as the directory name in step 1)

    If you are using a shell compatible with the Bourne shell, insert the
    following lines in the shell startup file:

	HUGINHOME=/usr/local/hugin
	export HUGINHOME

    The "sh" and "ksh" shells use "$HOME/.profile" as the startup file; and
    the "bash" shell uses "$HOME/.bashrc" as the startup file.


 3. The Sun Java interpreter (the "java" command) must be in your search path.
    If necessary, edit your shell settings of the "path" variable.

    Alternatively, the "hugin" shell script can be edited to use the full path
    of the correct Java interpreter.

    Note that a 32-bit Java interpreter is required for this software (due to
    the use of native code).


DOCUMENTATION
-------------

    The documentation for the Hugin software is located in the "doc"
    subdirectory.
