The toric package for toric varieties ------------------------------------ "toric" is a package that implements some computations related to toric varieties and combinatorial geometry in GAP. With "toric", affine toric varieties can be created and related information about them can be calculated. "toric" is written entirely in the GAP language by D. Joyner. Please send your bug reports to support@gap-system.org. Installing toric ---------------- To install "toric" (as a GAP4 Package) unpack the archive file in a directory in the `pkg' hierarchy of your version of GAP4. (This might be the `pkg' directory of the GAP4 home directory.) On a *nix system, this is accomplished by (1) copying toric.tar.gz into the `pkg' subdirectory, (2) typing (as root, if necessary) `tar zxvf toric.tar.gz'. Loading toric ------------- After starting up GAP, the "toric" package needs to be loaded. Load "toric" by typing at the GAP prompt: gap> LoadPackage( "toric" ); or gap> RequirePackage( "toric" ); If "toric" isn't already in memory, it is loaded and a small banner is displayed. Bug reports ----------- When sending a bug report to support@gap-system.org, remember we will need to be able to reproduce the problem; so please include: * The version of GAP you are using; either look at the header when you start up GAP, or at the gap> prompt type: VERSION; * The operating system you are using e.g. Linux, SunOS 5.8 = Solaris 2.8, IRIX 6.5, Windows, ... * The compiler (if any) you used to compile the binaries and the options you used. Type: gcc -v or: cc -version. * A script that demonstrates the bug, along with a description of why it's a bug (e.g. by adding comments to the script - recall comments in GAP begin with a #). - David Joyner (wdj@usna.edu) August 21, 2004
