#  Prints a file, i.e. a TODO file, only once per shell session.
#
#  Examples:
#
#  cp todo_reminder ~/.`whoami`_pwdrc
#  chmod 600 ~/.`whoami`_pwdrc
#  echo Tomorrow I have to go to mirkwood > ~/TODO
#
#  cp ~/.`whoami`_pwdrc /tmp/
#  echo a temporary todo > /tmp/TODO
#
#  cd ~/
#  cd /tmp
#

### CONFIGURE HERE ###

TODO_FILE="TODO"

#
# uncomment this if you want the output of your TODOs shuffled. If you keep
# one entry per line, in the TODO, it is very useful, because changing the
# order of their output keeps your attention
