I'm thinking that if I ever give it to somebody it's possible they might

"~/" or something and end up deleting all their files, which I'd like to
How would that best be avoided ?
Is that something to do with chroot which I don't know anything about.

  always put things in a subdirectory.

  there is normally a directory named .local/share/<program-name>/
used for such things (or create it if it isn't there).

  if you have any configuration information that can be saved in
the .config/<program-name>/ directory (or again create it if it
isn't there).


Ah Ok, I could assert a directory and then the output directory make
that a subdirectory.
so if they typed "~/"
 "./images_out/~/" would cause an error ?

 a directory called "~/" might be tricky to delete ?
