  "Face schemes for LysKOM.

This variable is an association list that defines the face and color
schemes in LysKOM. The car of each element is the scheme key, a
symbol, and the cdr is a list of face definitions. Each face
definition in turn is a list of four elements: the face name, the base
face, foreground color and background color. When LysKOM defines a
face from such a specification, the base face is first copied and then
the foreground and background colors are set. If it permissible to
substitute nil for any element except the face name.

For instance, (kom-me-face bold \"yellow\" \"red\") will cause kom-me-face
to be bold with yellow text on a red background."
