I would instead suggest using path and environment variables to differentiate. Then when you test and "release" your script, you don't need to edit it.

I used an alias to update my path and environment variables quickly, so I could switch between the versions I had available. [You might find Perl useful for this as well -- simply pushing a new directory on the front of the path can make it grow very quickly.]
