%description
This project creates RAM based block device (named ramzswap) which
acts as swap disk. Pages swapped to this disk are compressed and
stored in memory itself.

Compressing pages and keeping them in RAM virtually increases its
capacity. This allows more applications to fit in given amount of
memory.
