 What if we wanted to use \c{libhello} in our own project? While the installed
 version is always an option, it may not be convenient when we develop our code.
 We may have multiple builds per project, for example, with GCC and Clang to
 catch all the warnings. We may also want to make sure our application works
 well with various versions of \c{libhello} (and maybe even with that heinous
-\c{1.1.0}). While we can install different configurations into different
+\c{1.1.x}). While we can install different configurations into different
 directories, it's hard to deny things are getting a bit hairy: multiple
 configurations, multiple installations... I guess we will have to get our hands
 into that cookie jar, I mean, configuration, again.
