I'm doing a lot of packaging/development jobs in different git
repositories.  Sometimes certain things needs to be done, but it's not
time to commit anything yet.  I am too lazy to use other TODO list
managers and often I just fail to remember that should be done in this
repository.

ztodo keeps per-path todo lists.  Entries are kept in associative array
(key is path) and cached in ~/.ztodolist file.  I've added ztodo call to
chpwd() finction, so I get reminder whenever I chdir to a directory.

.zshrc:
autoload -Uz ztodo
chpwd() { ztodo }

Sample session:

~ $ cd src
~/src $ ztodo add 'Collect underpants'
~/src $ ztodo add '?'
~/src $ ztodo add 'PROFIT!'
~/src $ cd .
You have 3 things to do here.
~/src $ ztodo list
 1: Collect underpants
 2: ?
 3: PROFIT!
~/src $ ztodo del 2
~/src $ ztodo list
 1: Collect underpants
 2: PROFIT!
~/src $ ztodo clear
~/src $ ztodo list
~/src $
