Quantum Package configuration script.

Usage:
  $(basename $0) -c <file>    
  $(basename $0) -h           
  $(basename $0) -i <package> 
  $(basename $0) -g [nvidia|intel|none]

Options:
  -c  <file>        Define a COMPILATION configuration file,
                    in "${QP_ROOT}/config/".
  -h                Print the HELP message
  -i <package>      INSTALL <package>. Use at your OWN RISK:
                    no support will be provided for the installation of
                    dependencies.
  -g [nvidia|intel|none]  Choose GPU acceleration

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

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