' Example for install scripts with freebasic

' provided the basic routine for registry access.

' Introduction
' -------------
' I wrote the following code "quick and dirty" for an install script to do
' the installation of a web application server (Apache Tomcat), a web service and
' the application itself (a dynamic pdf created with Crystal Xcelsius) at once
' without too much bothering the user.
'
' Install scripts are needed when the facilities of standard installer build programs (I used
' www.gksetup.com) are not sufficient. In this case the installer had to start an additional
' setup, find the current version of java runtime, fetch the appropriate path to java home
' and write it to system environment variable before launching the just installed server
' program and the application itself.

' It are these kind of tasks - read and write registry things and fire up external commands -
' where freebasic proved to be quite smart.
