I know that everyone strongly recommends against CPU mining, however, I would like to know if CPU mining is still possible however inefficient it may be?  CGMiner appears to have dropped support for CPU mining even though there is a CPU version that is still included as of 3.3.1:

Q: What happened to CPU mining?
A: Being increasingly irrelevant for most users, and a maintenance issue, it is
no longer under active development and will not be supported. No binary builds
supporting CPU mining will be released. Virtually all remaining users of CPU
mining are as back ends for illegal botnets. The main reason cgminer is being
inappopriately tagged as a virus by antivirus software is due to the trojans
packaging a CPU mining capable version of it. There is no longer ANY CPU mining
code in cgminer. If you are mining bitcoin with CPU today, you are spending
1000x more in electricity costs than you are earning in bitcoin.

Are there any other mining programs that still do CPU mining for either bitcoin or litecoin?
