@opindex chuid
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 run gpgsm for
another user. 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 only an effect
when used on the command line. This option has currently no effect at
all on Windows.
@item --extra-digest-algo @var{name}
@opindex extra-digest-algo
Sometimes signatures are broken in that they announce a different digest
