Component extraction/muxing operations are not already in place, and
doing it this way is bound to be significantly slower since it would
involve quite a few copies of the data.

The operations on the webpage are the full set of operations compiled
and installed by default for the previous release. A website
documenting your source tree can be found in docs/operations.html, you
can even make that documentation document the work in progress
operations in operations/workshop/ by invoking make there, and
invoking make in docs/ again.
