Anything-sync-daemon (asd) is a tiny pseudo-daemon designed to manage
user specified directories referred to as sync targets from here on
out, in tmpfs and to periodically sync them back to the physical disc
(HDD/SSD). This is accomplished via a symlinking step and an innovative
use of rsync to maintain synchronization between a tmpfs copy and
media-bound backups. Additionally, asd features several crash recovery
features.
