Change the current user to @var{uid} which may either be a number or a
name. This can be used from the root account to get information on
the GnuPG environment of the specified user or to start or kill
daemons. If @var{uid} is not the current UID a standard PATH is set
and the envvar GNUPGHOME is unset. To override the latter the option
@option{--homedir} can be used. This option has currently no effect
