wand.RdThe 'libmagic' library provides functions to determine 'MIME' type and other metadata from files through their "magic" attributes. This is useful when you do not wish to rely solely on the honesty of a user or the extension on a file name. It also incorporates other metadata from the mime-db database https://github.com/jshttp/mime-db
The header checking is minimal (i.e. nowhere near as comprehensive as libmagic) but
covers quite a bit of ground. If there are content-check types from
magic sources
that you would like coded into the package, please file an issue and
include the full line(s) from that linked magic.tab that you would like mapped.
