That is why moving everything to 'lib/' and thinking about the rest
later will not work.  Instead, moving a specific component to a
specific subdirectory (not 'lib/') would be a reasonably
self-contained first step.  Consider 'builtin/' as an example:  it
is focused, and anyone can easily tell what the criterion is.  If
it is the top-level cmd_foo() implementation, it goes there;
otherwise, it does not.  Then, you can proceed to the second step,
and then the third.  Iterate enough times, and the top level will
become thin enough that you can either make your final step a
no-op and leave the remaining files there, or create one last
group to house the hodgepodge of leftover bits and move them there.

Again, this is because you are trying to do everything at once.
Instead, come up with one clear concept, name it well, move the
related files there, and then iterate.
