I can reproduce it.

HOME=/nonexistent/nemo /usr/share/doc/sympow/examples/samples.sh

No need, the ideal wish is already patched. It was patched by the Debian maintainer himself (me):
Sorry I forgot this part of the story; and I should document further this feature (I am agree).
The concerned patch is d/p/upstream-system_wide.patch [1]. Details can be found in the header
of the path. The involved environment variable is SYMPOW_CACHEDIR :

Assuming that the user has a HOME, let launch the sample script:

	$ /usr/share/doc/sympow/examples/samples.sh

Data are put in $HOME/.sympow

Now, assuming some /scratch space, let do:

$ mkdir -p /scratch/$USR/sympow
$ SYMPOW_CACHEDIR=/scratch/$USR/sympow /usr/share/doc/sympow/examples/samples.sh

Now data are put in /scratch/$USR/sympow .

Of course, the following command fails:

HOME=/nonexistent/nemo /usr/share/doc/sympow/examples/samples.sh


At the time of writing the patch, I guessed that HOME does always exist.
This is my major mistake.

So, the issue solved.

Having said that, I am on my way to see how I can improve the visibility of this patched
material.

Thanks,
Jerome

PS: to my defence, it was one of my first Debian package.
