This directory contains the latest version of the Unix distribution of PARI/GP. This is Pari-2.1. Versions 1.3xxx and 2.0xxx are in the OLD directory. For people wanting to use the readline facilities, take also readline-4.1.tgz if it's not already installed on your system. hosttype is a shell script which gathers information about your hardware/architecture. It is not needed to install PARI, only to report success in (most) usable form for the MACHINES file.
