\chapter{Undocumented Modules \label{undocumented-modules}}  The modules in this chapter are poorly documented (if at all).  If youwish to contribute documentation of any of these modules, please get intouch with\ulink{\email{docs@python.org}}{mailto:docs@python.org}. \localmoduletable  \section{\module{applesingle} --- AppleSingle decoder}\declaremodule{standard}{applesingle}  \platform{Mac}\modulesynopsis{Rudimentary decoder for AppleSingle format files.}  \section{\module{buildtools} --- Helper module for BuildApplet and Friends}\declaremodule{standard}{buildtools}  \platform{Mac}\modulesynopsis{Helper module for BuildApplet, BuildApplication and                macfreeze.} \deprecated{2.4} \section{\module{cfmfile} --- Code Fragment Resource module}\declaremodule{standard}{cfmfile}  \platform{Mac}\modulesynopsis{Code Fragment Resource module.} \module{cfmfile} is a module that understands Code Fragments and theaccompanying ``cfrg'' resources. It can parse them and merge them, and isused by BuildApplication to combine all plugin modules to a singleexecutable. \deprecated{2.4} \section{\module{icopen} --- Internet Config replacement for \method{open()}}\declaremodule{standard}{icopen}  \platform{Mac}\modulesynopsis{Internet Config replacement for \method{open()}.} Importing \module{icopen} will replace the builtin \method{open()}with a version that uses Internet Config to set file type and creatorfor new files.  \section{\module{macerrors} --- Mac OS Errors}\declaremodule{standard}{macerrors}  \platform{Mac}\modulesynopsis{Constant definitions for many Mac OS error codes.} \module{macerrors} contains constant definitions for many Mac OS errorcodes.  \section{\module{macresource} --- Locate script resources}\declaremodule{standard}{macresource}  \platform{Mac}\modulesynopsis{Locate script resources.} \module{macresource} helps scripts finding their resources, such asdialogs and menus, without requiring special case code for when thescript is run under MacPython, as a MacPython applet or under OSX Python. \section{\module{Nav} --- NavServices calls}\declaremodule{standard}{Nav}  \platform{Mac}\modulesynopsis{Interface to Navigation Services.} A low-level interface to Navigation Services.  \section{\module{PixMapWrapper} --- Wrapper for PixMap objects}\declaremodule{standard}{PixMapWrapper}  \platform{Mac}\modulesynopsis{Wrapper for PixMap objects.} \module{PixMapWrapper} wraps a PixMap object with a Python object thatallows access to the fields by name. It also has methods to convertto and from \module{PIL} images. \section{\module{videoreader} --- Read QuickTime movies}\declaremodule{standard}{videoreader}  \platform{Mac}\modulesynopsis{Read QuickTime movies frame by frame for further processing.} \module{videoreader} reads and decodes QuickTime movies and passesa stream of images to your program. It also provides some support foraudio tracks. \section{\module{W} --- Widgets built on \module{FrameWork}}\declaremodule{standard}{W}  \platform{Mac}\modulesynopsis{Widgets for the Mac, built on top of \refmodule{FrameWork}.} The \module{W} widgets are used extensively in the \program{IDE}.
