The argument after the b key is the number of (1024 byte) blocks per write.
The default is 10, 32 if the density is 6250 or greater.

The c key, for use with cartridge tapes, sets the density to 1000 bpi,
and the tape length to 1700 feet.

The comments in dump.8 are wrong.  Dump writes in BSD directory format,
so the output can be read by the stock BSD restore.  The obsolete and
undocumented e key dumps directories in EFS format, which only this
version of restore understands.  There is no reason to use the e key.

I've mailed an updated dump.8 to Mike Muus at BRL.

>3. Is source available?

Dump contains some code derived from SGI source, so I can't sent
it to you unless you have an IRIX source license.  Sorry.
