Quantum Package configuration script.

Usage:
  $(basename $0) -c <file>    | --config=<file>
  $(basename $0) -h           | --help
  $(basename $0) -i <package> | --install=<package>

Options:
  -c, --config=<file>      Define a COMPILATION configuration file,
                           in "${QP_ROOT}/config/". 
  -h, --help               Print the HELP message
  -i, --install=<package>  INSTALL <package>. Use at your OWN RISK:
                           no support will be provided for the installation of
                           dependencies.

Example:
  ./$(basename $0) -c config/gfortran.cfg

Note:
  Users are encouraged to create their own configuration files instead of
  modifying the existing ones.
