This package depends on two other python packages:
Growl is not required. It’s only used to pop an error message when a requested command cannot be found.
To install Growl’s binding, follow the instructions on their page. (The bindings are in Growl’s SDK disk image, not the installation image! You can find it on Growl’s sources page).
To install qslaunch, simply open a terminal and type:
$ sudo easy_install qslaunch
If appscript is not installed, it should be handled automatically by easy_install.
If using pip, you can install it directly from the mercurial repository:
$ sudo pip install hg+http://bitbucket.org/greyw/qslaunch/
