! Description:
! ------------
! Perform namelist file check. The program is independent from PALM and used by 
! the shell script "mrun" to check the parameter files (e.g. p3d, p3df...) b
! efore the job is submitted/started. Source code from the PALM model in used in 
! check_namelist_files by means of the cpp directive "__check". The compiled
! program resides in the SCRIPTS folder as check_namelist_files.x.
