Usage is like:
mtee 'cat > /tmp/passwd1' 'grep a > /tmp/passwd2' 'grep b > /tmp/passwd3' < /etc/passwd...this constructs three pipelines, all running against the same stdin read once, and written 3 times, all independent of each other aside from running against the same input data.
Another form of usage:

Oct 24 2005:
Modified to allow use of "-f filename" to read a list of commands from filename
Mar 9, 2005:
Modified to use 1 megabyte blocks, instead of lines. It's now much
faster on large files.
