This package will install

                   ctools-$VERSION and gammalib-$VERSION

for Mac OS X 10.7 or later.

Installation requires approximately 260 MB of disk space. The package
will be installed in the directory /usr/local/gamma, hence you need
administrator privileges to do the install.

Simply click on the installer package and follow the instructions.
The installation will take less than one minute.

After installing the package, you have to initialise the ctools
environment. This will be done by invoking an initialisation script
that can be found in the /usr/local/gamma/bin directory.

To invoke this script you need to add the following to your .bashrc 
or $HOME/.profile script:

    export CTOOLS=/usr/local/gamma
    source \$CTOOLS/bin/gammalib-init.sh

If you use C shell or a variant then add the following to your
.cshrc or .tcshrc script:

    setenv CTOOLS /usr/local/gamma
    source \$CTOOLS/bin/gammalib-init.csh

More information on ctools can be found at
http://cta.irap.omp.eu/ctools/.

If you encounter problems in installing or using this package, please
send your error report to jurgen.knodlseder@irap.omp.eu. In your report,
please specify your Mac OS X version and Python version and the problem
you're facing.
