* Where will the variable “srctree” be set for the file “scripts/nsdeps”?

* Would you like to support a separate build directory for desired adjustments?

* How do you think about to check error handling around such commands?

I suggest to assign the name for the temporary file to a variable
which should be used by subsequent commands.
