New Revision: 13333

Modified:
   main/trunk/pym/portage/sets/libs.py
Log:
Add a LibraryFileConsumerSet class that can be used to rebuild all packages
that consume one or more given files. Note: This does not detect libtool
archive (*.la) files that consume the specified files (revdep-rebuild is able
to detect them).
