In some HPC facilities, the access to the internet is limited for security
reasons.  In such an environment, the installation of QP is sometimes very
painful because the OCaml compiler and the libraries can't be installed by a
non-root user.

This command creates a self-contained binary distribution in the form of a
tar.gz file that can be copied on another machine.


Usage:

    $(basename $0) [-h|--help]

Options:

    -h    --help    Prints the help message

Note:

    There can be conflicts due to the version of Glibc. The machine on which |QP| is
    compiled should be the oldest one.
