-# so here we test for conditions of a script under ssh and return if so. To test
-# for an overriding condition, we have a few options. one is to use an
-# environment variable. env variables sent across ssh are strictly limited. ssh
-# -t which sets $SSH_TTY, but within a script that won't work because tty
-# allocation will fail. We could override an obscure unused LC_var, like
-# telephone, but I don't want to run into some edge case where that messes
-# things up. we could transfer a file which we could test for, but I can't think
-# of a way to make that inherently limited to a single ssh command. I choose to
-# set SendEnv and AcceptEnv ssh config vars to allow the environment variable
+# So here we test for conditions of a script under ssh and return if so.
+# And we don't keep the rest of the code in this file, because even
