First Version of the package
Installation
- The first step is to install GAP. Refer to http://www.gap-system.org for instructions on how to install GAP on your system.
- forestalg needs two third-party packages to work: automata (http://www.gap-system.org/Packages/automata.html) and sgpviz (http://www.gap-system.org/Packages/sgpviz.html). Follow the specific installation steps for each of these packages in their respective documentation
- The two above packages depend on external software to work: graphviz (http://www.graphviz.org/) and a PostScript viewer must be installed on your system and available in the PATH for your user. Note that neither are strictly required except for all drawing functions.
- To install forestalg itself, expand the package archive into the pkg/ directory of your GAP installation (this is platform dependent; refer to the GAP documentation for your system). If you installed GAP using the gap-core Debian or Ubuntu package, this directory is /usr/share/gap/pkg. On UNIX, if you don't have write access to this directory you can expand the archive in a subfolder gap/pkg/ of your home directory, or use the -l option of GAP to load the package from any directory.
- Before using the package, you must load it with the command LoadPackage("forestalg");
