+------- QUICK-INSTALL for the iRRAM package ----------------------------------
|
| For the compilation of the iRRAM package, you need the packages GMP and MPFR:
|
|  (1) you can use versions of GMP and MPFR already installed on 
|      your system (if available) 
|
| or
|
|  (2) this script can download and compile own versions (installed locally).
|      The self-compiled versions might be a bit faster than those already 
|      contained in your system.
