%description
A successor to compcache, zRam, has been already integrated in the Linux kernel
for a while now. This means that no additional compilation nor tweaking is
required to benefit from compressing memory on the fly and massively reduced
swapping.

This package contains command line scripts zramswapon, zramswapoff to enable
zRam devices as required, or at boot time via a systemd service.

Individual Compressed RAM Block Devices are created based on cores/threads
available, the size of each block device is calculated on cores/threads divided
by total ram installed. The final total is then added to system swap.
