+# **Pocco** is a Python port of [Docco](http://jashkenas.github.com/docco/ ):
+# the original quick-and-dirty, hundred-line-long, literate-programming-style
+# documentation generator. It produces HTML that displays your comments
+# alongside your code. Comments are passed through
+# [Markdown](http://daringfireball.net/projects/markdown/syntax), and code is
+# passed through [Pygments](http://pygments.org/) syntax highlighting.  This
+# page is the result of running Pocco against its own source file.
+#
+# If you install Pocco, you can run it from the command-line:
+#
+#     pocco src/*.py
+#
+# ...will generate linked HTML documentation for the named source files, saving
+# it into a `docs` folder.
+#
+# To install Pocco, simply
+#
+#     sudo setup.py install
+#
+
+#### Main Documentation Generation Functions
+
+# Generate the documentation for a source file by reading it in, splitting it
+# up into comment/code sections, highlighting them for the appropriate language,
+# and merging them into an HTML template.

+    generate_html(source, sections)
+
+# Given a string of source code, parse out each comment and the code that
+# follows it, and create an individual **section** for it.
+# Sections take the form:
+#
+#     { "docs_text": ...,
+#       "docs_html": ...,
+#       "code_text": ...,
+#       "code_html": ...,
