usage: bv [-h] [-v] [command...]

Command used to start any BrainVISA related program.

It is meant to be used from outside a container, and runs commands inside a
container.

Used without parameter, it starts a graphical interface
allowing the configuration of the environment.

optional arguments:
  -h, --help     show this help message and exit
  -v, --verbose

Currently bv is just a shorthand to the "casa_distro run" command, and follows
the same syntax and options. In the future it will change to more
"conventional" arguments syntax (say, "--opengl container" instead of
"opengl=container").
