# redirect output to log file. this doesn't work. todo figure out why
# commands. when a local script runs an ssh command, this file should not be
# sourced by default, but we should be able to override that.
#
-# 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
-# BASH_LOGIN_SHELL to propagate across ssh.
-
-# assume we want ssh commands to source this file if we are sourcing it,
-# and we haven't specified otherwise already
-[[ ! $BASH_LOGIN_SHELL ]] && export BASH_LOGIN_SHELL=true
-
-# first conditions show that we are an ssh command without an interactive shell
+# 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
+# though we return, we already parsed the whole code, and as I develop
+# the code, the parsing can have errors, which can screw up cronjobs
+# etc.
+#
+# 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. However, I do use -t for
+# strange hosts, so we consider it an indicator. 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
+# BASH_LOGIN_SHELL to propagate across ssh. This also requires that we
+# wrap ssh in interactive shells, because, once we export the var, it
+# will go into scripts, and we want it to be nondefault there.
