"""Search through the subfolders of the current folder. For each subfolder found,
chdir() to it, then run all executable scripts ending in .SH in that folder.
Does not exhaustively search for subfolders of subfolders, or subfolders of
subfolders of subfolders, etc.; it only does exactly what was described in that
first sentence, without recursion.

Note that this calls scripts in an insecure way:

    subprocess.call(script_name, shell=True)

so it should only be called on scripts that are trusted completely.
