+dwz is a dwarf compressor
+
+DWARF optimization and duplicate removal tool
+
+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 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.
+
+sourcecode licence is GPL2. see COPYING and COPYING.RUNTIME for more
+details.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
