Make it clear that optional components must not break when disabled,
that openssl is the only officially supported library and its support
must not be broken, and that bug fixes must always be detailed.
While at it use "You" instead of "They" as in the context
it seems to make more sense to refer to "you", as it is
you that are going to be running the command, there is no
"they".
