-DESCRIPTION
-     archive_read_next_header()
-	     Read the header for the next entry and return a pointer to a
-	     struct archive_entry.  This is a convenience wrapper around
-	     archive_read_next_header2() that reuses an internal struct
-	     archive_entry object for each request.
-     archive_read_next_header2()
-	     Read the header for the next entry and populate the provided
-	     struct archive_entry.
-
-RETURN VALUES
-     These functions return ARCHIVE_OK (the operation succeeded), ARCHIVE_WARN
-     (the operation succeeded but a non-critical error was encountered),
-     ARCHIVE_EOF (end-of-archive was encountered), ARCHIVE_RETRY (the opera-
-     tion failed but can be retried), and ARCHIVE_FATAL (there was a fatal
-     error; the archive should be closed immediately).
-
-ERRORS
-     Detailed error codes and textual descriptions are available from the
-     archive_errno() and archive_error_string() functions.
