The PyPy project will build a portable, fast, flexible, context-aware
programming platform supporting Very-High Level Languages (VHLL) to
yield significant productivity gains in software development. PyPy's
flexible, modular runtime system will be well-suited for networked,
embedded, and mobile devices.

VHLLs' high semantic level can help extend context-awareness, beyond
the basics (time, location, identity), to a wider variety of context
information and actions. However, VHLLs can often produce slow or large
application and supporting code, hampering their use for small devices.
We will solve this problem via the innovative concept of ObjectSpaces,
high-level formulations of language interpreter components. Explicit,
clear separation of parts yields modularity and flexibility.
ObjectSpaces are themselves coded in a VHLL and can be specialised for
execution speed, memory consumption, or other parameters.

PyPy will use and target the widely-used Open Source programming
language Python, first developed in 1990 at CWI (Centrum voor Wiskunde
en Informatica) in the Netherlands. By producing the new reference
version of the language, we will have a large impact on the estimated
175,000 Python programmers worldwide. Emphasizing simplicity and
readability, Python has wider appeal among non-programmers, and
particularly among women, than languages perceived as needing extensive
mathematical training and ability. An improved Python can thus help
somewhat in promoting social cohesion and gender equality.

PyPy will leverage known European strengths in formal methods and
languages, operating by a novel Agile Software Development methodology
for distributed development, including short, high-productivity
meetings known as "Sprints". Systematic efforts to spread the knowledge
produced by the project among academics, SMEs, industry, and other
interested parties, will ensure the project's results and achievements
are fully exploited.
