help [option]
Print a summary of the available options or, if option is given, a detailed list of
the valid switches for the option.

info -i filename [-v]
Dump the header information from a drive image.

verify -i fileiname [-ip filename]
Validate the MD5/SHA1 on a drive image.

createraw -o filename [-op filename] [-f] -i filename [-isb offset] [-ish offset] [-ib
length] [-ih length] -hs bytes -us bytes [-c none|type1[,[...]]] [-np processors]
Create a new compressed raw image from a raw file.

createhd -o filename [-op filename] [-f] [-i filename] [-isb offset] [-ish offset] [-ib
length] [-ih length] [-hs bytes] [-c none|type1[,[...]]] [-chs cylinders,heads,sectors]
[-ss bytes] [-np processors]
Create a new compressed hard disk image from a raw file.

[-np processors]
Create a new compressed CD image from a raw file.

createld -o filename [-op filename] [-f] -i filename [-isf offset] [-if length] [-hs
bytes] [-c none|type1[,[...]]] [-np processors]

copy -o filename [-op filename] [-f] -i filename [-ip filename] [-isb offset] [-ish
offset] [-ib length] [-ih length] -hs bytes [-c none|type1[,[...]]] [-np processors]
Copy all hunks of data from one CHD file to another. The hunk sizes do not need to
match. If the source is shorter than the destination, the source data will be
padded with 0s.

addmeta -i filename -t tag [-ix index] [-vt text] [-vf filename] [-nocs]
Add metadata to the chd.
