datapacker is a tool to group files by size such
that they fill fixed-size containers (called
"bins") using the minimum number of containers.
This is useful, for instance, if you want to
archive a number of files to CD or DVD, and want
to organize them such that you use the minimum
possible number of CDs or DVDs. In many cases,
datapacker executes almost instantaneously. Of
particular note, the hardlink action can be used
to effectively copy data into bins without having
to actually copy the data at all. datapacker is a
tool in the traditional Unix style; it can be used
in pipes and call other tools.
