Boa Constructor is a cross-platform RAD GUI-building IDE. It offers visual frame creation and manipulation, an object inspector, a debugger, integrated help, and many views on the source, including inheritance hierarchies, object methods and properties, and HTML generated from documentation strings. It is written in Python and uses the wxPython toolkit which wraps wxWindows.
cgi_buffer is a group of libraries that may be used to improve performance of CGI scripts (and other content generation engines) in some circumstances by applying performance-enhancing HTTP mechanisms that are typically not supported by them. Currently, Perl, Python, and PHP4 are supported. The Python library may also be used as a wrapper around another CGI script.
FXPy is a Python extension module which provides an interface to the FOX cross-platform GUI library. With a few minor exceptions, FXPy provides a complete interface to FOX. FOX is a C++-based toolkit for developing graphical user interfaces easily and effectively, and it runs natively under both Unix/X and Microsoft Windows. Some of the significant features of FOX include a rich set of widgets, powerful but easy-to-use layout managers, extensive support for 3-D modeling using OpenGL or Mesa, drag-and-drop (using the XDND protocol) and a registry for persistent application settings.
GCache is a Python module that provides a generic cache class useful for speeding up any application where objects are referenced by keys. It uses object metadata to optimize hit-rates and freshness for fetches, and uses a "write-through" mechanism for writes and deletes. It can use "if-modified-since" fetches or rsync delta updates to refresh stale cached objects. GSource classes are provided for generating useful metadata from common sources (os.stat calls and MIME headers). A simple example urlCache is implemented that supports HTTP 1.1 (rfc2616) cache-control and expire headers to ensure freshness. Also included is an rfc2616 package useful for parsing HTTP 1.1 headers, and a PCache package implementing a persistant cache using a Python shelve.
The Geospatial Data Abstraction Library (GDAL) is a unifying C/C++ API for accessing raster geospatial data, and currently includes formats like GeoTIFF, Erdas Imagine, Arc/Info Binary, CEOS, DTED, GXF, and SDTS. It is intended to provide efficient access, suitable for use in viewer applications, and also attempts to preserve coordinate systems and metadata. Python, C, and C++ interfaces are available.
getmail is intended as a simple, secure, and reliable replacement for fetchmail. It retrieves email (either all messages, or only unread messages) from one or more POP3, SPDS, or IMAP4 servers (with or without SSL) for one or more email accounts, and reliably delivers into qmail-style Maildirs, mboxrd files, or through external MDAs (command deliveries) specified on a per-account basis. getmail also has excellent support for domain (multidrop) mailboxes, including delivering messages to different users or destinations based on the envelope recipient address.
GLE is a library package of C functions that draw extruded surfaces, including surfaces of revolution, sweeps, tubes, polycones, polycylinders and helicoids. Generically, the extruded surface is specified with a 2D polyline that is extruded along a 3D path. A local coordinate system allows for additional flexibility in the primitives drawn. Extrusions may be texture mapped in a variety of ways. The GLE library generates 3D triangle coordinates, lighting normal vectors and texture coordinates as output. GLE uses the GL or OpenGL API's to perform the actual rendering.
