421 # Description: A database file as used by mlocate, a fast implementation
422 # of locate/updatedb. It uses merging to reuse the existing
423 # database and avoid rereading most of the filesystem. It's
424 # the default version of locate on Arch Linux (and others).
425 # File path: /var/lib/mlocate/mlocate.db by default (but configurable)
426 # Site: https://fedorahosted.org/mlocate/
427 # Format docs: http://linux.die.net/man/5/mlocate.db
428 # Type: mlocate database file
