Bug#595758: synclient: man page and -h disagree about valid options
synclient -h lists different options from what the man page specifies, and one
of these is invalid (-?).
$ synclient -h
Usage: synclient [-s] [-m interval] [-h] [-l] [-V] [-?] [var1=value1 [var2=value2] ...]
-m monitor changes to the touchpad state (implies -s)
interval specifies how often (in ms) to poll the touchpad state
-l List current user settings
-V Print synclient version string and exit
-? Show this help message
var=value Set user parameter 'var' to 'value'.
Neither the help nor the man page say what -s is (maybe use SHM? see syndaemon man page).
Usage says -h is valid but does not say it shows the help message.
Both Usage and the man page say -? is valid, too, whereas empirical evidence says it is
not; using it results in an 'invalid option' error message.
The man page says:
For the -m and -h options, SHM must be enabled by setting the option SHMConfig "on" in your
But even though SHMConfig is not on, -h does appear to work. Maybe they meant -s?
