couple of things to set up:
export PATH=$PATH:"C:\cygwin\home\hliu\working_dir\todo.txt_cli-2.7"
chmod +x todo.sh
mv todo.cfg ~/.
(make some changes on todo.cfg, like define location of todo.txt and colors)
in .bashrc
alias t='todo.sh -d C:/cygwin/home/hliu/todo.cfg'
some commands
t add "go to drug store"
t do 1
t pri 1 A
t depri 1 A
t ls
