Using Coda as the editor for SVN/Git commit messages from command line

blocking-coda.sh

#!/bin/bash
# Allows Coda to be used as the editor for writing commit messages.
# Add blocking-coda to the PATH along doing chmod u+x on it, and 
# then set it as your commit message editor by adding to your .profile:
#  export SVN_EDITOR=blocking-coda
#  git config --global core.editor blocking-coda
# Assumes that you are using iTerm2, which you should! http://www.iterm2.com/
# Once you save the file, iTerm will regain focus. 
# Tip: when finished writing the commit message, close the file to invoke the 
# Save File dialog so that the temporary commit message file will be saved 
# and closed at the same time, since you don't need it anymore.
