--- The following code isolates the generic context code from already defined or to be defined
--- namespaces. This is the reference loader for plain, but the generic code is also used in
--- luaotfload (which is is a file meant for latex) and that used to be maintained by Khaled
--- Hosny. We do our best to keep the interface as clean as possible.
---
--- The code base is rather stable now, especially if you stay away from the non generic code. All
--- relevant data is organized in tables within the main table of a font instance. There are a few
--- places where in context other code is plugged in, but this does not affect the core code. Users
--- can (given that their macro package provides this option) access the font data (characters,
--- descriptions, properties, parameters, etc) of this main table.
---
--- Future versions will probably have some more specific context code removed, like tracing and
--- obscure hooks, so that we have a more efficient version (and less files too). So, don't depend
--- too much on low level code that is meant for context as it can change without notice.
