19archive file the `gunzip' step above may already be done by the browser,
20although the name of your file may still have the misleading `.gz'
21extension.)
22
23Do this preferably (but not necessarily) inside the `pkg' subdirectory
24of your GAP 4 installation. It creates a subdirectory called `help'.

26 The package uses the software 4ti2 <Cite Key="4ti2"/> and/or normaliz and hence is only properly working
27 on systems which have at least one of the two installed. normaliz
28 may be installed via the GAP-package NormalizInterface,
29 see the documentaion of this package for details.
30 For more information on 4ti2 and to download it, please visit
31 <URL Text="www.4ti2.de">http://www.4ti2.de</URL>.
32 To interact with these external softwares the package makes use of the
33 4ti2-Interface and normaliz-Interface written by S. Gutsche, C. Söger and M. Horn,
34 The 4ti2-Interface in turn uses the package IO, that needs a C-part to be compiled;
35 see the readme-file or the documentation of the IO-package for details.

37This completes the installation of the package.
