Modified path to qemu package source to /sf/adapt/qemu
This is to conform with the convention that adaptation-level packages
should be located in /sf/adapt rather than /sf/adaptation.
This is an interim workaround for bug 3744.
Examples of classes that implement special operators (see reference manual):
Complex.py Complex numbers
Dates.py Date manipulation package by Tim Peters
Dbm.py Wrapper around built-in dbm, supporting arbitrary values
Range.py Example of a generator: re-implement built-in range()
Rev.py Yield the reverse of a sequence
Vec.py A simple vector class
bitvec.py A bit-vector class by Jan-Hein B\"uhrman
(For straightforward examples of basic class features, such as use of
methods and inheritance, see the library code.)
