Browse source 
Split options out of the "@table @var" section and create a "@table
@option", then use whitespaces and blank lines consistently.

Command parameters:
@table @var
@item filename
is a disk image filename
@item --object @var{objectdef}
is a QEMU user creatable object definition. See the @code{qemu(1)} manual
page for a description of the object properties. The most common object
type is a @code{secret}, which is used to supply passwords and/or encryption
keys.
@item --image-opts
Indicates that the source @var{filename} parameter is to be interpreted as a
full option string, not a plain filename. This parameter is mutually
exclusive with the @var{-f} parameter.
@item --target-image-opts
Indicates that the @var{output_filename} parameter(s) are to be interpreted as
a full option string, not a plain filename. This parameter is mutually
exclusive with the @var{-O} parameters. It is currently required to also use
the @var{-n} parameter to skip image creation. This restriction may be relaxed
in a future release.
is a disk image filename
@item fmt
is the disk image format. It is guessed automatically in most cases. See below
for a description of the supported disk formats.
@item --backing-chain
will enumerate information about backing files in a disk image chain. Refer
below for further description.
@item size
is the disk image size in bytes. Optional suffixes @code{k} or @code{K}
(kilobyte, 1024) @code{M} (megabyte, 1024k) and @code{G} (gigabyte, 1024M)

@item output_fmt

@item options
is a comma separated list of format specific options in a
name=value format. Use @code{-o ?} for an overview of the options supported
by the used format or see the format descriptions below for details.
@item snapshot_param
is param used for internal snapshot, format is
'snapshot.id=[ID],snapshot.name=[NAME]' or '[ID_OR_NAME]'
@item snapshot_id_or_name
is deprecated, use snapshot_param instead

will enumerate information about backing files in a disk image chain. Refer

@item -c
indicates that target image must be compressed (qcow format only)
@item -h
with or without a command shows help and lists the supported formats
@item -p
display progress bar (compare, convert and rebase commands only).
If the @var{-p} option is not used for a command that supports it, the
progress is reported when the process receives a @code{SIGUSR1} or
@code{SIGINFO} signal.
@item -q
Quiet mode - do not print any output (except errors). There's no progress bar
in case both @var{-q} and @var{-p} options are used.
@item -S @var{size}
indicates the consecutive number of bytes that must contain only zeros
for qemu-img to create a sparse image during conversion. This value is rounded
down to the nearest 512 bytes. You may use the common size suffixes like
@code{k} for kilobytes.
@item -t @var{cache}
specifies the cache mode that should be used with the (destination) file. See
the documentation of the emulator's @code{-drive cache=...} option for allowed
values.
@item -T @var{src_cache}
specifies the cache mode that should be used with the source file(s). See
the documentation of the emulator's @code{-drive cache=...} option for allowed
values.
