README file for the `HeLP' GAP4 package
To get the newest version of this GAP 4 package download one of the
archive files
HeLP-x.x.tar.gz
and unpack it using
gunzip HeLP-x.x.tar.gz; tar xvf HeLP-x.x.tar.
(Note that if you use a browser like `netscape' for downloading the
archive file the `gunzip' step above may already be done by the browser,
although the name of your file may still have the misleading `.gz'
extension.)
Do this preferably (but not necessarily) inside the `pkg' subdirectory
of your GAP 4 installation. It creates a subdirectory called `help'.
The package uses the software 4ti2 and/or normaliz and hence is only properly working
on systems which have at least one of the two installed. normaliz
may be installed via the GAP-package NormalizInterface,
see the documentation of this package for details.
For more information on 4ti2 and to download it, please visit
https://4ti2.github.io .
To interact with these external softwares the package makes use of the
4ti2-Interface and normaliz-Interface written by S. Gutsche, C. Söger and M. Horn,
The 4ti2-Interface in turn uses the package IO, that needs a C-part to be compiled;
see the readme-file or the documentation of the IO-package for details.
This completes the installation of the package.
E-mail us if there are any questions, remarks, suggestions. Also, we
would like to hear about applications of this package.
