   @jtulach please have a look at this code:
   
   
https://github.com/apache/netbeans/blob/d2e1813a533e4b0a48034f47077a5239e8ca45cf/nb/ide.launcher/unix/netbeans#L36-L39
   
   I think this is what @neilcsmith-net meant by "a different way to how other 
paths are absolutized". My understanding is, that this saves the current 
directory into variable `old`, then `cd`s to the path denoted by parent of 
`$progdir`. Invoking `pwd` will now give you the path when the parent of 
`$progdir` is resolved against the current directory. That value is stored into 
`$basedir` for later usage. As we are now at the wrong location in the 
directory tree, we `cd` back into the start directory (using the value from 
`$old`).
   
   This might not be the most efficient way, but it looks sane to me and is 
small enough to be copyable (IMHO).
