Please send bug reports to roeder.marc@gmail.com

       	    	Requirements
		-----------

RDS requires GAP version >=4.5 and L. Soicher's DESIGN package version
>=1.3 (which in turn depends on the GRAPE package).


		Installation
		---------

1. Download one of the archives

	rds<ver>.tar.bz2
	rds<ver>.tar.gz
	rds<ver>.zoo
	rds<ver>-win.zip

   (where <ver> is some version number) to the directory pkg/ of the
   GAP home directory. If you do not have permission to do so, create
   a directory called gap/pkg in your home directory.


2. change directory to pkg/ and unpack the archive using the according command:

	tar -xjf rds<ver>.tar.bz2
	tar -xzf rds<ver>.tar.gz
	zoo -extract rds<ver>.zoo
	unzip rds<ver>-win.zip

 (replace <ver> with the version number)

3. start GAP. If you have created the directory gap/pkg in your home
   directory, use "gap -l '<homedir>/gap;'" where <homedir> is the path of
   your home directory (use "pwd" to find out what it is, if you don't know)

4. Type "LoadPackage("rds");" to load the RDS package
