registry_doc = """Summary of the Win32 API Registry interfaces.

Concepts:
    A _directory_ is a collection of key/value pairs.
    You need a _handle_ for a directory to do anything with it.
    There are some predefined keys, e.g. HKEY_LOCAL_MACHINE.
    A _key_ is an ASCII string; NT file system conventions apply.
    A _value_ has a type and some data; there are predefined types
    (e.g. REG_SZ is a string, REG_DWORD is a 4-byte integer).
    There's some fishiness in that in fact multiple, named values
    can appear under each key, but this seems little used (in this
    case, the value is best seen as a structured value).
    A key can also refer to a _subdirectory_.  In this case the
    associated value is typically empty.  To get a handle for a
    subdirectory, use RegOpenKey(handle, key).  The key can also
    be a backslash-separated path, so you can go directly from one of
    the predefined keys to the directory you are interested in.

Most common functions:
    RegOpenKey(handle, keypath) -> handle
        Get a handle for an existing subdirectory
    RegCreateKey(handle, keypath) -> handle
        Get a handle for a new subdirectory
    RegDeleteKey(handle, key)
        Delete the given subdirectory -- must be empty
    RegCloseKey(handle)
        Close a handle
    RegGetValue(handle, subkey) -> string
        Get the (unnamed) value stored as key in handle
    RegSetValue(handle, subkey, type, value)
        Set the (unnamed) value stored as key in handle, with given
        type; type should be REG_SZ
    RegSetValueEx(handle, name, reserved, type, value)
        Set the value with given name to the given type and value;
        currently reserved is ignored and type should be REG_SZ

Functions to list directory contents (start counting at 0, fail if done):
    RegEnumKey(handle, i)
        Return the i'th subkey
    RegEnumValue(handle, i)
        Return the i'th name and value

Lesser used functions:
    RegFlushKey(handle)
        Flush the changes to the handle to disk (like Unix sync())
    RegSaveKey(handle, filename, reserved)
        Save the contents to a disk file (broken?!)
    RegLoadKey(handle, keypath, filename)
        Load the contents from a disk file (lots of restrictions!)
