GeoToad is written in an interpreted scripting language, Ruby, it already comes with the source code in the non-Windows distributions. For Windows we use RubyScript2Exe to compile it into an .exe file, so if you would like to modify the script, grab the generic download from the Downloads page.

However, if you would like to check-out the latest unreleased development source code, you'll need to grab a Subversion client. You can then anonymously checkout the repository via:

Submitting Changes

If you see a bug, or are just interested in helping out, contact me and I can give you write access to the repository.

If you wish to submit patches, please use unified diff format. Here is an example of how I generate patches, assuming you have two directories: One version of geotoad with your fix (+locfix) and one directory with the original source code in it.
