-h/-help

Function
This lists out command-line help giving you how many and what types of parameters are listed. There is no difference between -h and -help. If a parameter is listed with <these> surrounding them, you must supply that parameter. If it surrounded with [brackets], it is optional and may be omitted. Doing so will set that parameter to a default value.

If you list a function name, or a portion of a name (i.e., mul), it will return just information on commands matching that string.
