I would like to make pysetup easier to work with when called from shell scripts or similar tools that wish to take action based on the exit code of the pysetup --search command. In this case return 0 if a match is found and 1 otherwise.

As an enhancement, print a message to stdout that the dist is not installed.

Example:

# pysetup -s Mako
Mako is not installed

# echo $?
1

pysetup is currently under heavy refactoring -- see the https://bitbucket.org/tarek/distutils2-new-cmdline clone if you want to help on this.

I am planning to merge it before the release, this week.

I will take a look, thanks.
