-Introduction
-============
-
-Text_Highlighter is a class for syntax highlighting. The main idea is to
-simplify creation of subclasses implementing syntax highlighting for
-particular language. Subclasses do not implement any new functioanality, they
-just provide syntax highlighting rules. The rules sources are in XML format.
-To create a highlighter for a language, there is no need to code a new class
-manually. Simply describe the rules in XML file and use Text_Highlighter_Generator
-to create a new class.
-
-
-This document does not contain a formal description of API - it is very
-simple, and I believe providing some examples of code is sufficient.
-
-
-Highlighter XML source
-======================
-
-Basics
-------
-
-Creating a new syntax highlighter begins with describing the highlighting
-rules. There are two basic elements: block and region. A block is just a
-portion of text matching a regular expression and highlighted with a single
-color. Keyword is an example of a block. A region is defined by two regular
-expressions: one for start of region, and another for the end. The main
-difference from a block is that a region can contain blocks and regions
-(including same-named regions). An example of a region is a group of
-statements enclosed in curly brackets (this is used in many languages, for
-example PHP and C). Also, characters matching start and end of a region may be
-highlighted with their own color, and region contents with another.
-
-Blocks and regions may be declared as contained. Contained blocks and regions
-can only appear inside regions. If a region or a block is not declared as
-contained, it can appear both on top level and inside regions. Block or region
-declared as not-contained can only appear on top level.
-
-For any region, a list of blocks and regions that can appear inside this
-region can be specified.
-
-In this document, the term "color group" is used. Chunks of text assigned to
-same color group will be highlighted with same color. Note that in versions
-prior 0.5.0 color goups were refered as CSS classes, but since 0.5.0 not only
-HTML output is supported, so "color group" is more appropriate term.
