Just a small script that renames all the JPEG files
in a folder as 0000.jpg, 0001.jpg etc. Initial order
is retained.

This is intended as a recipe script, though I use it
way too often to arrange my digital files.

Note that this has possible error conditions that
are not handled at all:
- what if the folder has files already numbered?
- while renaming, it fails if the target file exists
