7# The following basic Linux magic is useful for reference, but using
8# "long" magic is a better practice in order to avoid collisions.

535# Summary:     Database file for mlocate
536# Description: A database file as used by mlocate, a fast implementation
537#              of locate/updatedb. It uses merging to reuse the existing
538#              database and avoid rereading most of the filesystem. It's
539#              the default version of locate on Arch Linux (and others).
540# File path:   /var/lib/mlocate/mlocate.db by default (but configurable)
