AVAILABLE SECTORS

available [-o | -? | sector]

Lists all available sectors. If sector numbers are specified, tells you if
those sectors are available or not.

-o      Print to stdout instead of a pager
-?      Get usage info
sector  Check if [sector] is available

For the sake of scripting, if one uses the [sector] parameter, the program
will exit successfully (exit code 0) if the sector is available, and
unsuccessfully (exit code 1) if it is not. (Keep in mind, exit code 1 is also
used for general errors, but hopefully this will help somebody writing a
script to see if multiple sectors are available or not).
