Waf is a Python-based framework for configuring, compiling, and installing applications to replace the whole GNU autotool chain (automake, autoconf, aclocal, autoheader, libtool, and make). It is extremely small (72kb), easy to redistribute (no installation required), and features several tools for building C, C++, Java, Gnome, C#, Qt4, or OCaml applications.
white_dune is a graphical VRML97/X3DV editor, simple NURBS/Superformula 3D modeller, animation tool, and VRML97/X3DV commandline compiler in development. VRML97 (Virtual Reality Modeling Language) is the ISO standard for displaying 3D data over the Web via browser plugins ("HTML for realtime 3D"). X3DV is the direct successor of VRML97. VRML97 and X3DV have support for animation, real-time interaction, and multimedia (images, movies, and sounds). white_dune can read, create, and display VRML97/X3DV files and let the user change the scenegraph/fields. It also has support for stereoscopic view via "quadbuffer"-capable stereo visuals, and support for 3D input devices like a joystick, spaceball, or magnetic tracker.
The system linkers provided with AIX 4.3, HP-UX 10.x, 11.x, and Compaq Tru64 UNIX 4.0, 5.0, 5.1 do not accept multiple runtime linker command-line arguments (-blibpath, +b, -rpath respectively). If multiple instances are specified, only one is used. This differs from how the Solaris and IRIX linkers work. This tool, wrapld, is a wrapper script around the AIX, HP-UX, and Tru64 UNIX ld command that accepts multiple runtime linker arguments and combines them into one runtime linker argument, separating the paths with colons.
Yruba provides a rule system similar to make or ant for the shell (bash). It provides a clear separation between a list of dependencies that must be up-to-date before the current task can be performed, an explicit test that checks whether the target is really out-of-date, and a command that finally makes the target. Everything is plain bash syntax, so there is no new command language to learn.
