The Guarana package is part of the standard distribution of GAP and so normally there should be no need to install it separately. If by any chance it is not part of your GAP distribution, then the standard method is to unpack the package into the `pkg' directory of your GAP distribution. This will create a `guarana' subdirectory. For other non-standard options please see Chapter Reference: Installing a GAP Package of the GAP Reference Manual. Note that the GAP-Packages Polycyclic and Polenta are needed for this package. Normally they should be contained in your distribution. If not, they can be obtained at http://www.gap-system.org/Packages/packages.html
If the Guarana Package is not already loaded then you have to request it explicitly. This can be done by `LoadPackage("guarana")'. The `LoadPackage' command is described in Section Reference: LoadPackage in the GAP Reference Manual.
Once the package is installed, it is possible to check the correct installation by running the test suite of the package.
gap> Read(Filename(DirectoriesPackageLibrary("guarana","tst")[1],"testall.g"));
Note that this now disables running of the tests in tst/guarana2.tst, since these require alnuth which in turn requires kash/kant. If your system has these prerequisites in place you can manually run those test examples as follows.
gap> ReadTest(Filename(DirectoriesPackageLibrary("guarana","tst")[1],"guarana2.tst"));
For more details on Test Files see Section Reference: Test Files of the GAP Reference Manual. If the test suite runs into an error, then please send a message to `jjm@mcs.st-andrews.ac.uk' including the error message.
