+Section: universe/devel
+Priority: optional

+Description: The E9Patch static binary rewriting system
+ E9Patch is a powerful static rewriting system for stripped x86_64 Linux ELF
+ and Windows PE binaries.  E9Patch is primarily designed for robustness, and
+ can scale to very large/complex binaries without introducing rewriting
+ errors.
+ .
+ This package also includes the E9Tool frontend for E9Patch.
