/**
 * Hubzilla.
 *
 * Hubzilla is an open source decentralised communications
 * platform combined with a decentralised identity/authentication framework
 * wrapped in an extensible content management system, providing website designers
 * the ability to embed fully decentralised communications and social tools
 * into many traditional website designs (blogs, forums, small business
 * websites, charitable organisations, etc.). Hubzilla also provides DNS mobility
 * and internet scale privacy/access control.
 *
 * This allows any individual website to participate in a matrix of linked
 * sites and people and media sharing which is far greater than the reach
 * of an individual site.
 *
 * If you are reading the source code and come across a function
 * or code block which is not documented, but you have a good idea what it
 * does, please add some descriptive comments and push it to the main project.
 * Even if your description isn't perfect, it gives us a base which we
 * can build on and correct - so that eventually everything is fully
 * documented.
