 %description devel
 Libextractor is a library used to extract meta-data from files of arbitrary type.
 It is designed to use helper-libraries to perform the actual extraction, and to be trivially extendable by linking against external extractors for additional file types.
+This package contains static libraries and header files needed for development.
