Quick script to determine if a set of Python packages work with Python 3
#!/usr/bin/env python
## Accepts a list of packages on stdin and prints whether each
## package is compatible with Python 3. The easiest way to
## use this script is by piping the output of `pip freeze`
## into it:
##
## $ pip freeze | py3-ready
##

Like `brew cat`, but automatically displays the output in a pager. Drop it in a directory on your $PATH and chmod +x it. Now you can run `brew less <formula>`!

Removes the crap that SSH puts in your console title bar when SSH'ing into a machine. Drop this in the ~/.bash_logout file on the remote machine.
