Beta release, Linux shell installer.
A Java runtime must be installed first, the Oracle JRE seems to work best.
After downloading the installation file set permissions to allow it to run and install it as follows (example is for 5.19, filename varies according to the download):
$ chmod 777 REW_linux_5_19.sh
$ sudo ./REW_linux_5_19.sh
Start REW by running
