Hi Hartmut,

Shall it become an absolute > path, or just the basename. this depends on what the user may reasonably expect from the script. If it’s a core feature of the tool then I would expect to be able to use it without having to manually install other packages. If it’s a rare or optional feature it could be fine to use the basename and assume that the user has the tool installed. Generally, I try to make sure that required tools are either propagated or that references to tools are made to absolute file names. There is no hard rule. -- Ricardo
