pfiles usage output is unhelpful

[sebroy]

pfiles usage indicates to run with -h option:

delphix@ac60101:/opt/delphix/server/bin$ pfiles --help
Usage: pfiles [-h]

Running with the -h option just gives the usage again though:

delphix@ac60101:/opt/delphix/server/bin$ pfiles -h 
Usage: pfiles [-h]  

Unfortunately, there's no man page either:

delphix@ac60101:/opt/delphix/server/bin$ man pfiles No manual entry for pfiles See 'man 7 undocumented' for help when manual pages are not available. 

Even if there are no other options to the command, it still seems like a basic help message on the order of what pmap -h provides would be useful.
