 Hello all,

 In the help it says:

 Getting help:
     -h      -- print basic options
     -h long -- print more options
     -h full -- print all options (including all format and codec specific
 options, very long)
     -h type=name -- print all options for the named
     See man ffmpeg for detailed description of the options.

 Print help / information / capabilities:
 -L                  show license
 -h topic            show help
 -? topic            show help
 -help topic         show help
 --help topic        show help
 -version            show version

 I began using ffmpeg with an older version and had expected "-h topic" to
 list topics I could begin to get help on, and there is where you could
 have placed the -h filter=name and amoung the entries you could offer an
 option to list terms which would allow to query the definition and usage
 of "command support/slice threading/timeline support" amoung others.

 So, if theres no point to "topic" can it be removed since it responds the
 same as just -h, or is it being backward compatible?
