7 ### This is a script to download and update the JREs used in the windows, mac (and maybe linux) installations, and update channel
8 ### It creates a structure with
9 ### ./jre-VERSION-OS-ARCH/jre/...
10 ### as used by getdown
12 ### ./tgz/jre-VERSION-OS-ARCH.tgz
13 ### which is an archive of the _contents_ of ./jre-VERSION-OS-ARCH/jre/ and used by install4j for the installer
15 ### Edited to use adoptium domain to gain access to Java 17 (LTS) versions.
