pkg_update.sh

#! /bin/sh

# This simple script is used to mass-update all package distribution files (eg,
# tarballs). It is intended to be used only by ESOS developers, and will not
# update any software on a running ESOS system. The script takes two arguments,
# the first is the data file, and the second is the directory containing all
# of the new package files.

# The data file contains two columns delimited by a single space character. The
# first column contains the old/current file name (eg, lzo-2.06.tar.gz) and the # second column contains the new package file name (eg, lzo-2.09.tar.gz).


# Make sure we got what we need
