The essential file is strap.jar (2.3 MByte) which can be started with the command java -jar strap.jar or by double click. A small helper file strap.bat (Windows), strap.command (Mac) or strap.sh (Linux) moves the jar file to the Strap folder $HOME/.StrapAlign/. It identifies existing Java installations. If needed, it will download and install Java for Windows, Mac or Linux on x86 platforms (50 to 80 MByte). For downloading Java, the script has the capability to detect web proxies. Finally it will start strap.jar. The same script file is used for installation and for running. Any Web-proxy will be automatically identified within Strap.
