Yes, I would need to add a unique marker based on 
CurrentProject::FilePath, is there a javascript function to calculate a 
hash of the file path?

So my case is:

$ cd ~/Projects/$project
$ ls
master
<branch1>
<branch2>
...

Each <branch> directory contains a git worktree, so they all have the 
same project name and so the same location and directory name for their 
build: ~/Projects/$project/build-<project>-<kit>-<config>, i would like 
to have 
~/Projects/$project/build-<project>-<kit>-<config>-<hash-of-project-filepath>.

Thanks,
Chris
