+SUMMARY="Meta data extraction tool and library"
+DESCRIPTION="GNU 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.  Common use-cases for \
+GNU libextractor include detail-views in file managers, detailed \
+search results in file-sharing networks and general information \
+gathering in forensics investigations and penetration testing."
