# This is a script to automate creating a VirtualBox VM and setting up Windows 98 within it
# in order to grab files from numerous localized versions of Windows 98 to gather up strings
# and jumpstart localization of jspaint.
# A better idea would have been to use an unattended answer file (msbatch.inf).
# I knew there would be sysadmin type ways of doing this, but I went this route I guess because I thought it was cool.
# It's a lot of work tho, and way less reliable.
