install.sh

#! /bin/bash

# PyOP2 quick installation script. Installs PyOP2 and dependencies.
#
# Usage: install.sh [user name]
#
#   When run with superuser privileges, user name is used for commands to be
#   run unprivileged if given. Otherwise $USERNAME is queried, which works
#   when calling this script with sudo but not when calling from a root shell.
