To download SINGULAR::PLURAL for a Unix platform

Make sure that you have approximately 12MByte of free disk space and follow these steps.

1. You need to download two (archive) files:

   SingularPlural-2-1-2-share.tar.gz

   contains architecture independent data like documentation and libraries (alternatively, you may also download SingularPlural-2-1-2-share.zip).

   SingularPlural-2-1-2-<uname>.tar.gz

   contains architecture dependent executables, like the SINGULAR::PLURAL program.

   <uname> is a description of the processor and operating system for which SINGULAR::PLURAL is compiled. Choose one of the following:

   ix86-Linux	PC's running under Linux with libc version 6 (e.g., for SuSe Linux distribution version >= 6; RedHat Linux distribution version >= 5.2).
   ix86-Linux-libc5	PC's running under Linux with libc version 5 (if you are not sure which libc version you have, run ldd /bin/ls).
   ix86-Win	PC's running Windows 95/98/NT/2K which have Cygwin version 1.0 (or higher) already installed. Unless you are familiar with Cygwin, we recommend that you download one of the self-extracting archives as described below.
   HPUX-9	HP workstations running under HPUX version 9
   HPUX-10	HP workstations running under HPUX version 10
   SunOS-5	Sun workstations running Solaris version 5
   IRIX-6	IRIX workstations running IRIX version 6
   AIX-4	AIX workstations running AIX version 4

   Please contact us if you can not find an appropriate architecture dependent archive.

2. Simply change to the directory in which you wish to install SINGULAR (usually wherever you install 3rd-party software):

   cd /usr/local/

   SINGULAR::PLURAL specific subdirectories will be created in such a way that multiple versions and multiple architecture dependent files of SINGULAR::PLURAL can peaceably coexist under the same /usr/local/ tree.

3. Unpack the archives:

   gzip -dc SingularPlural-2-1-2-<uname>.tar.gz | tar -pxf - gzip -dc SingularPlural-2-1-2-share.tar.gz | tar -pxf -

   If you have downloaded SingularPlural-2-1-2-share.zip, unpack with

   unzip -u SingularPlural-2-1-2-share.zip

4. After unpacking, see the created file Plural/2-1-2/INSTALL (which is also located at ftp://www.mathematik.uni-kl.de/pub/Math/Singular/INSTALL_unix.html for details on how to finish the installation.
