distutils.extension.Extension:
Just a collection of attributes that describes an extension
module and everything needed to build it (hopefully in a portable
way, but there are hooks that let you be as unportable as you need).
itools.handlers.base.Handler:
This class represents a resource handler; where a resource can be a
file or a directory, and is identified by a unique key.
itools.xmlfile.xmlfile.XMLFile:
An XML file is represented in memory as a tree where the nodes are
instances of the classes 'Element' and 'Raw'.
itools.html.xhtml.XHTMLFile:
This class adds one thing to the XML class, the semantics of
translatable text.
itools.html.html.HTMLFile:
HTML files are a lot like XHTML, only the parsing and the output is
different, so we inherit from XHTMLFile instead of TextFile, even if the
mime type is 'text/html'.
itools.datatypes.datetime_.HTTPDate:
This datatype is named "HTTPDate" for historical reasons, but supports
many of the date formats used in Internet protocols.
