afsio is a command to pipe data into or out of afs files

afsio bypasses the cache manager to achieve higher throughput.
However, it uses the cache manager to stat or create files over the
AFS path.

Besides 'apropos' and 'help' there are 3 subcommands:

'write'	pipes data into a new or empty AFS file

'append' pipes data at the end of an existing AFS file

'read' pipes data out of an AFS file

for 'write' there is an option '-md5' which calculates on the fly
the md5 chscksum and prints it to stdout. (Useful when you create
long time archives to keep it separately for later ...)

for 'write' there is also an option '-synthesize <size>' to do just
performance tests. It creates a file which contains at the
begin of each 4 KB block the offset printed in ascii.

for all subcommands exists a '-verbose' option which writes to
stderr data rate and timing information.

All three subcommands may also be used prefixed with 'fid' accepting
then a Fid instead of an AFS path. With the 'fid' prefix also a '-cell'
option is allowed.
