Install from binaries
---------------------

(1) Extract files:

    zcat gel-0.9-bin.tar.gz | tar xvvf -

(2) Make wrapper script:

    cd gel-0.9
    ./mk-wrapper.sh `pwd`

(3) [Required for Wildfire] Copy wrapper script to a directory in your
    PATH, e.g. $HOME/bin/

    cp tree-grid-script $HOME/bin

(4) [Optional] To use the Globus executor, you must configure your CA
    certificates and user key/certificate.

    Obtain a valid Globus key and certificate.  By default, these
    should be placed in .globus/user{cert,key}.pem .

    By default the interpretor will look for CA certificates in
    /etc/grid-security/certificates.  To use a different collection of
    certificates, you can insert the line

    cacert=/path/to/ca/certificates/

    in your .globus/cog.properties file.  For convenience, the
    certificates and signing policies for the common CAs used in BII
    can be found in etc/grid-security/certificates .

(1) Extract files:
