#!/bin/sh
# This script gets and installs a package from the Website.
# It is called by getpack package1 ...
# A package must be in the form of pack.tar.bz2 and must
# include a build script that makes and installs it.
# The build script should succeed if installation works, else fail
# Examples:
# easypack awk elle telnet # fetch and install 3 packages
# easypack -o awk elle telnet # fetch and replace existing packs
SOURCE_DIR=/usr/src/commands # where the source is deposited
OVERWRITE=0 # can an installed package be overwritten?
SOFTWARE_DIR="http://www.minix3.org/software" # Tested and approved S/W
BETA_DIR="http://www.minix3.org/beta_software" # Untested software
