libmagic-mime-ocaml-dev 1.2.0-1build1 (arm64 binary) in ubuntu jammy

 This library contains a database of MIME types that maps filename
 extensions into MIME types suitable for use in many Internet
 protocols such as HTTP or e-mail. It is generated from the mime.types
 file found in Unix systems, but has no dependency on a filesystem
 since it includes the contents of the database as an ML
 datastructure.

 This package contains development files.
