mlocate is a new locate implementation. The "m"
stands for "merging", because updatedb reuses the
existing database to avoid re-reading most of the
file system. This makes updatedb faster and does
not trash the system caches as much.

The locate(1) utility is intended to be
completely compatible to slocate. It also attempts
to be compatible to GNU locate, when it does not
conflict with slocate compatibility.
