I've changed to hardcode gcc as compiler, which is more likely to work. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Prepared by David Joyner (2007-21-10) This directory contains several "official" and "undeposited" GAP packages available from http://www.gap-system.org/Packages/packages.html. They are all released under the GPL with the following exception: (*) grape contains Brendon McKay's nauty program. To load a package, for example grape, into SAGE type sage: gap('LoadPackage("grape")') All these packages come with documentation in the doc or htm subdirectory (e.g., for grape, it would be in SAGEHOME/local/lib/gap-4.4.10/pkg/grape/htm). After loading all the packages, you can type gap_reset_workspace() so you don't have to reload them again. A brief description of each package follows: braid is a GAP package for computing with braids, covering curves, and Hurwitz spaces. (Authors: K. Magaard, S. Shpectorov and H. Voelklein) crime - package to compute the cohomology ring of finite p-groups, induced maps, and Massey products. (Author: Marcus Bishop) cryst - Computing with crystallographic groups (Authors: Bettina Eick, Franz Gähler, Werner Nickel) CTblLib - The GAP Character Table Library (Author: Thomas Breuer) DESIGN is a package for classifying, partitioning and studying block designs. (Author: Leonard H. Soicher) FactInt is a package providing routines for factoring integers, in particular: * Pollard's p-1 * Williams' p+1 * Elliptic Curves Method (ECM) * Continued Fraction Algorithm (CFRAC) * Multiple Polynomial Quadratic Sieve (MPQS) (Author: Stefan Kohl) GAPDoc is a package containing a definition of a structure for GAP documentation, based on XML. It also contains conversion programs for producing text-, DVI-, PDF- or HTML-versions of such documents, with hyperlinks if possible. (Authors: Frank Luebeck, Max Neunhoeffer) GRAPE is a package for computing with graphs and groups, and is primarily designed for constructing and analysing graphs related to groups, finite geometries, and designs. (Author: Leonard H. Soicher) HAP (Homological Algebra Programming) is a GAP package providing some functions for group cohomology computation. (Author: Graham Ellis) HAPcryst - an extension package for HAP, which allows for group cohomology computation for a wider class of groups. (Author: Marc Roeder) LAGUNA - this package provides functionality for calculation of the normalized unit group of the modular group algebra of the finite p-group and for investigation of Lie algebra associated with group algebras and other associative algebras. (Authors :Victor Bovdi, Alexander Konovalov, Richard Rossmanith, Csaba Schneider) polymake - an interface with the (standalone) polymake program used by HAPcryst. (Author: Marc Roeder) SONATA ("System Of Nearrings And Their Applications") is a package which constructs finite nearrings and related objects. (Authors: Erhard Aichinger, Franz Binder, Jürgen Ecker, Peter Mayr, Christof Noebauer) TORIC is a GAP package for computing with toric varieties. (Author: David Joyner)
