-### This is a script to download and update the JREs used in the windows, mac (and maybe linux) installations, and update channel
-### It creates a structure with
-### ./jre-VERSION-OS-ARCH/jre/...
-### as used by getdown
-### and
-### ./tgz/jre-VERSION-OS-ARCH.tgz
-### which is an archive of the _contents_ of ./jre-VERSION-OS-ARCH/jre/ and used by install4j for the installer
