The normal operation for this program is to read the configuration file
and then become a daemon and execute commands as the HID items specify.

The debouce value is an integer not less than 0. The value of 0
indicates that no debouncing should occur. A value of 1 will only
execute the action when the state changes. Values greater than one

changes by that amount.

The action is a normal command that is executed with

Before it is executed some substitution will occur:
`$n' will be replaced by the nth argument on the
command line, `$V' will be replaced by the numeric value
of the HID item, `$N' will be replaced by the name
of the control, and `$H' will be replaced by the name
