It is just an access to query things on a target.  The main use is to access OS data independently on the type of communication channel or if the OS is remote or native.

If the target is a "remote" one (I guess it is the only one that currently implements this), a 'q' packet will be sent and the first argument (type) will be sent as a single character after the 'q'.

Other targets may do things differently, but you should get back the value (as a string) of whatever target object you have requested.
