We have not used an off-the-shelf tool for the following
reasons:
- we have not found a command line tool with source code

is pretty close to what we wanted - a specialized home-grown tool provides flexibility for future automations
...
The assumptions explained in the overview can be understood as
limitations: treecomp.py overview#Assumptions
...
- paths are not normalized
- toy examples can't be run, because there are no scripts to undo the
effects, what in turn breaks the unit-tests.
(see using treecomp.py#toy use.)
