 %description
-Dwz is 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 the 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.

 The tool handles DWARF 32-bit format debugging sections of versions
 2, 3 and 4 and GNU extensions on top of those, though using DWARF 4
