pipemeter - 1.1.5-1.1 main

pipemeter can be inserted in a shell command between two programs
passing data via pipe, or between a file and a program reading from
stdin, and show the speed and amount of data that has passed through.
If reading from a regular file, or passed a size, a progress meter is
also shown.
.
Command line switches allow tuning of block size and display interval.
Size parameters have support for dd style block size specification.
.
Pipemeter is intended to be very lightweight, with no dependencies.
