.SH SYNOPSIS
.B snap.ro
.I device
.IB key = value

.SH DESCRIPTION
This is a fake snapshot handler.  Rather than produce a snapshot device
containing a consistent view of the origin's contents, it does nothing
at all.
.PP
The following options keys are recognized, either with a
.RB ` .trivial '
suffix or without.  Other keys are reported as errors, unless the key
contains a
.RB ` . '
character.
.TP
.BI op= op
The
.I op
must be either
.B snap
(the default) or
.BR unsnap .
In the former case, the
.I device
name is printed to standard output; in neither case does
.B snap.trivial
actually do anything substantive.
.TP
.BI tag= tag
This option is accepted and ignored.
