Help message

  Usage: 
   fluids.sh -id {ID} {-ib|-it|-ic|-st|-sp & spec.para.} [-s {digits} -o {outfile} -r|-R -ref {REF} -si|-u '{%t}...{%g}']
   fluids.sh [-R] -show 
   fluids.sh [-u '{%t}...{%g}'|-si] -units
   fluids.sh -h|--help

  Common options:
   -id            NIST ID of the substance (e.g. C7732185 = Water)
   -s             number of digits in output (default: 5)
   -o             name of the output file (default: fluids_*.dat)
   -r             resolve substance name of NIST ID
   -R             like '-r' and enforce to renew catalogue
   -ref           standard state convention (default: "default for fluid")
   -si            use SI units instead of default
   -u             define units (use '-units' for more info)
   -show          print the catalogue of available substances (NIST IDs) and exit
   -units         print a help about handling of units and exit
   -h, --help     print this help and exit
   -V, --version  print version number and exit
