PyDO 2.0.1

PyDO is an object-relational mapping library for Python that is easy to use, explain and extend.
PyDO project supports multiple database systems, including PostgreSQL, MySQL, SQLite, MSSQL, and Oracle.
Main features:
Uses Python
Python is easy to learn for both new programmers and experts alike senior programmer types like it too (vs. say tcl) extensible with C/C++ for speed and/or linkage to C/C++ libraries via static *or* dynamic linking
Extensible
Relatively simple extension API can easily handle authentication, url building/parsing and custom tags
Encourages component based design
more than just "include"
not just another ASP/JSP like thing
a powerful templating language
encouraged by caching options (see below)
component output can be either HTML or Python objects
can write components in either STML or Python
can also call components on other skunk servers
Message Catalogs
makes multi-lingual sites much easier
support variable substitution in messages
Speed
templates are compiled to Python bytecode
extensive caching (to disk and optionally memory) of:
compiled forms of templates
digested message catalogs
output of components
python modules and python components
cache *is* sharable between machines if using a shared filesystem! (can be more than one shared filesystem for speed, redundancy and flexibility)
caching is flexible and as finite as your disk space
components can be rendered after the response is sent if a slightly stale version is available --- resulting in better response times
Documentation
extensive documentation available in HTML, PostScript, PDF & text (ok, not yet, but getting there fast) have automatic documentation tools to generate documentation for STML templates and python modules (python components coming soon) as well as tools for writing manuals.
Enhancements:
- This release adds support for sqlite3, and better support for aggregate functions.
