How to package Octave packages
What is Octave?
The definition from website says:
"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."

Spec Templates for Octave packages
There are two types of Octave packages: arch-specific and noarch.

- Octave package template
Summary of differences between arch-specific and noarch octave packages
- Noarch packages set
BuildArch: noarch - Don't require a specific api version
- No build step needed, just install from the source tar ball
- Noarch packages don't install anything into %{_libexecdir}/octave/packages
Octave packaging tips
Naming of Octave packages
Packages of Octave packages have their own naming scheme. They should take into account the upstream name of the package. This makes a package name format of octave-$NAME. When in doubt, use the name of the module that you type to import it in octave.
Examples:
octave-java (Octave package named java) octave-gsl (Octave package named gsl)
unset TERM
Due to an issue with octave emitting an escape sequence (due to readline library) on startup, you need to unset the TERM variable in the %build and %install sections.
Updating the octave package database
Octave maintains a list of installed packages in /usr/share/octave/octave_packages that needs to be updated on package install and removal. This file is in an octave plain-text format.
The contents of the /usr/share/octave/packages/ directory are scanned for the follwing files when performing a pkg('rebuild') from within octave.
- /usr/share/octave/packages/NAMEOFPACKAGE/packinfo/COPYING
- /usr/share/octave/packages/NAMEOFPACKAGE/packinfo/DESCRIPTION
If these files are not present in any give NAMEOFPACKAGE directory, then octave will silently skip the folder and fail to index it correctly.
Octave will use the contents of octave_packages to modify its path at startup, allowing octave to find plugins.
Documentation files
All package files are installed into the octave directories. The COPYING and DESCRIPTION files are documentation and need to be marked as %doc. The others are not.
