+Preprocessors, patterns and postprocessors need to then be wrapped
+together into an extension, which should be implemented as a class
+that extends markdown.Extension and should over-ride the
+``extendMarkdown()`` method. ``extendMarkdown()`` is called during
+markdown construction, giving the extension a pointer to the markdown
+object (the ``md`` parameters) and markdown's global variables
+(``md_globals``), which in theory gives the extension an option of
+changing anything it cares to change. However, what it really should
+be doing is inserting preprocessors, postprocessors and patterns into
+the markdown pipeline:
+
+
+ def extendMarkdown(self, md, md_globals) :
+
+ self.md = md
+
+ # Insert a preprocessor before ReferencePreprocessor
+ index = md.preprocessors.index(md_globals['REFERENCE_PREPROCESSOR'])
+ preprocessor = FootnotePreprocessor(self)
+ preprocessor.md = md
+ md.preprocessors.insert(index, preprocessor)
+
+
+If the extension uses any parameters that the use may want to change,
+they should be stored in self.config in the following format:
+
+ self.config = {parameter_1_name : [value1, description1],
+ parameter_2_name : [value2, description2] }
+
+When stored this way the config parameters can be over-riden from the
+command line or at the time Markdown is instantiated:
+
+ markdown.py -x myextension(SOME_PARAM=2) inputfile.txt > output.txt
+
+Note that parameters should always be assumed to be set to string
+values, and should be converted at the run time, e.g.
+
+ i += int(self.getConfig("SOME_PARAM"))
+
+Each extension should ideally be placed in its own module starting
+with ``mdx_`` prefix (e.g. ``mdx_footnotes.py``). The module must
+provide a module-level function called ``makeExtensions`` that takes
+as an optional parameter a list of configuration over-rides and
+returns an instance of the extension. E.g.:
+
+ def makeExtension(configs=None) :
+ return FootnoteExtension(configs=configs)

+See the implementation of footnote support (mdx_footnotes.py) for an
