Usage: ${0##*/} [OPTION]
       ${0##*/} [OPTION] directory
options:
  -0                use cleanCase0 instead of cleanCase
  -case <dir>       specify starting directory, default is cwd
  -self             avoid Allclean script (prevent infinite recursion)
  -help             print the usage

Recursively clean an OpenFOAM case directory.
By default uses Allclean, Allwclean when present.
