Pengines docs

An additional place that I hoping to make a better place to find anything useful with Prolog is Useful Prolog references

The nice points about this page are:

  1. It is indexed by major search engines.
  2. The more people that make links to the page, the higher up it will appear in search engine results.
  3. It is a Discourse Wiki so any one with Trust level: Basic can edit it.

I know you have lots of useful information on the web about Prolog, such as How To sites, YouTube videos and others, please add them to Useful Prolog references
