Summary     : A tool for monitoring the progress of data through a pipeline

Description :

PV ("Pipe Viewer") is a tool for monitoring the progress of data through a

pipeline.  It can be inserted into any normal pipeline between two processes

to give a visual indication of how quickly data is passing through, how long

it has taken, how near to completion it is, and an estimate of how long it

will be until completion.
