```
Usage: opendeco [OPTION...] 
Implementation of Buhlmann ZH-L16 with Gradient Factors:

 Dive options:
  -d, --depth=NUMBER         Set the depth of the dive in meters (or feet in
                             imperial mode)
  -t, --time=NUMBER          Set the time of the dive in minutes

  -g, --gas=STRING           Set the bottom gas used during the dive, defaults
                             to Air

  -p, --pressure=NUMBER      Set the surface air pressure in bar, defaults to
                             1.01325bar

  -r, --rmv=NUMBER           Set the RMV during the dive portion of the dive in
                             l/min, defaults to 20

  -i, --imperial             Use imperial depth units (fsw)

 Deco options:
  -L, --gflow=NUMBER         Set the gradient factor at the first stop,
                             defaults to 30

  -H, --gfhigh=NUMBER        Set the gradient factor at the surface, defaults
                             to 75

  -G, --decogasses=LIST      Set the gasses available for deco

  -S                         Only switch gas at deco stops

  -6                         Perform last deco stop at 6m (or 20ft in imperial
                             mode)

  -R, --decormv=NUMBER       Set the RMV during the deco portion of the dive in
                             l/min, defaults to 15

  -T, --showtravel           Show travel segments in deco plan

 Informational options:
      --licenses             Show third-party licenses

  -?, --help                 Give this help list
      --usage                Give a short usage message
  -V, --version              Print program version

Mandatory or optional arguments to long options are also mandatory or optional
for any corresponding short options.

Examples:

  ./opendeco -d 18 -t 60 -g Air
  ./opendeco -d 30 -t 60 -g EAN32
  ./opendeco -d 40 -t 120 -g 21/35 -L 20 -H 80 --decogasses Oxygen,EAN50
