ACF Libraries

Because of using lua, a very small language, the need arises to build everything from scratch. This can lead to some confusion, apprehension, or just feeling overwhelmed. Here is documentation on what we have now in the form of libraries and common functions. We hope to build some more and use this information to get the juices flowing in regard to ACF.

Some of these are lua libs or ones written for ACF. We are also using as a standard the lposix library which is documented here LPOSIX
