define Package/libextractor/description
  GNU Libextractor is a library used to extract meta data from files.
  The goal is to provide developers of file-sharing networks, browsers or
  WWW-indexing bots with a universal library to obtain simple keywords and meta
  data to match against queries and to show to users instead of only relying on
  filenames.
