gcm.F90 @ 3837

Last change on this file since 3837 was 3836, checked in by jbclement, 3 days ago

COMMON:
Rework related to the command-line parsing:

Replace ad-hoc argument parsing with a unified 'parse_args' subroutine, allowing easier extension to other programs and options across models;;
Use of '--version' (with ab optional output file) to print compilation/version details;
Addition of 'job_timelimit_mod' module to handle SLURM/PBS job time-limit via '--jobid' (currently only used in the PEM), allowing easier extension to other programs;
Replace manual SSO handling with 'parse_args' for the Mars start2archive;
Clean-up related legacy code in the programs supporting the version option.
