usage: sge2slurm [-h] [--shell SHELL] [--version] [sge_script]
  Translates SGE batch script to Slurm
  
  Derived from https://github.com/NIH-HPC/pbs2slurm/blob/master/pbs2slurm.py
  
  The SGE script is split into 
  - a shebang line
  - a header containing all the SGE options denoted by #$
  - the commands the script actually executes
  
  The script then:
  - Outputs the shebang line. If no shebang line was detected a default
    of #!/bin/bash is added.
  - Translates #$ directives into their #SBATCH counterparts when 
    applicable. Note that not all options are handled in this script.
    For a full list of SBATCH directives see the Slurm documentation at:
    https://slurm.schedmd.com/sbatch.html
  - Translates common SGE environment variables into their Slurm 
    counterparts
    
  If no input file is provided, sge2slurm will read from stdin.
  All output is sent directly to stdout i.e the console. sge2slurm should
  not overwrite the script unless directed by the user.
  
  Please be sure to manually go over translated scripts and make any 
  neccesary corrections.
  
  Examples:
      sge2slurm sge_script
