+%description
+The dwz package contains a program that attempts to optimize DWARF
+debugging information contained in ELF shared libraries and ELF executables
+for size, by replacing DWARF information representation with equivalent
+smaller representation where possible and by reducing the amount of
+duplication using techniques from DWARF standard appendix E - creating
+DW_TAG_partial_unit compilation units (CUs) for duplicated information
+and using DW_TAG_imported_unit to import it into each CU that needs it.
