1482# These functions are useful when a lib in your package changes --soname. Such
1483# an example might be from libogg.so.0 to libogg.so.1. Removing libogg.so.0
1484# would break packages that link against it. Most people get around this
1485# by using the portage SLOT mechanism, but that is not always a relevant
1486# solution, so instead you can add the following to your ebuilds:
1487#
1488# src_install() {
1489# ...
1490# preserve_old_lib /usr/$(get_libdir)/libogg.so.0
1491# ...
1492# }
1493#
1494# pkg_postinst() {
1495# ...
1496# preserve_old_lib_notify /usr/$(get_libdir)/libogg.so.0
1497# ...
1498# }
