GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language.
Octave-Forge is a central location for the collaborative development of packages for GNU Octave.
The Octave-Forge packages contains the source for all the functions and are designed to work with the GNU Octave package system.
g-octave is a tool that generates and installs ebuilds for Octave-Forge packages "on-the-fly" to Gentoo Linux, using Portage, Paludis or pkgcore. It's capable to generate ebuilds and Manifest files (if needed) for the packages, and to install them using an autogenerated overlay (named g-octave). g-octave can also handle patches to the packages automatically. The command line interface tries to be very similar to the interface of the emerge tool.
g-octave have some basic dependencies:
All the settings are centralized on the file /etc/g-octave.cfg. Please read the comments and change what you need. The recommendation is to keep everything as it is. :)
You can also use environment variables to configure g-octave.

The users can help testing and reporting bugs in our issue tracker. If you can help programming in Python you're always welcome. :)
g-octave ebuilds are available on the Git repository, or the Gentoo science overlay.
If you experienced some random errors when installing packages, please retry, using the option --force-all, and report the issue to us. If you don't want to lose all your ebuilds, you can try to use the option --force, that will re-create only the affected ebuild.
