deal.II is a C++ library supporting the generation of complex adaptive finite element codes. It features locally-refined grids, various scalar and vector-valued finite elements, linear solvers of low and higher order, arbitrary mappings, and support for 1, 2, and 3D computations. It comes with extensive documentation and example programs showing the use of the library for modern finite element programs.
Cameleon is an integrated development environment for Objective Caml and eventually other languages. Its features include a graphical user interface, configuration management based on CVS, easy access to and browsing of documentation, various editors, customizable file types, a plug-in architecture, and a highly customizable interface.
LibCVS Perl simplifies the job of writing tools around CVS by providing Perl libraries that programmers can access directly in their code. Its current focus is libraries that use the cvsclient protocol to talk to a CVS server and are targetted at the development of client applications. Libraries that understand the RCS file format and provide fast server-side access are a future possibility.
OpenGrok is a fast and usable source code search and cross reference engine. It helps you search, cross-reference, and navigate your source tree. It can understand various program file formats and version control histories like Mercurial, Bazaar, Git, ClearCase, Perforce, SCCS, RCS, CVS, or Subversion. In other words, it lets you grok (profoundly understand) the source.
