1467# These functions are useful when a lib in your package changes --soname. Such
1468# an example might be from libogg.so.0 to libogg.so.1. Removing libogg.so.0
1469# would break packages that link against it. Most people get around this
1470# by using the portage SLOT mechanism, but that is not always a relevant
1471# solution, so instead you can add the following to your ebuilds:
1472#
1473# src_install() {
