currently, some old methods still remain in the rewrite branch, for backward-compatibility.
but i think as a rewrite version, such methods can be removed, or replaced with new methods and properties,
to make new code cleaner.
also, for convinence, we can provide some simple wrapper classes, which map old methods to new ones.
and put them in some package such as pywikibot.wrappers.*. for example, pywikibot.wrappers.Page.
try to make them have the same interfaces as old version (trunk version?).
and this may make porting old scripts easier (just by writing from pywikibot import wrappers as wikipedia etc.).
