Yes: This is really a convention, used to allow easy
updates. We create libFoo.so.93 and link it to libFoo.so
When we upgrade, we leave 93 in place, add 94
and link 94 to libFoo.so
If an existing program needs version libFoo.so.93, it can get it,
but by default it just uses libFoo.so as the thing to link
to. Does that help?
