Many MySQL interfaces and tools float around the Interwebs. GUI's in particular tend to be very feature-rich. ReptileSQL tries to be different. It's designed as a step up from the mysql command line program, adding a nice, graphical shell and improved usability.
If you are using Ubuntu, installing the 'python-mysqldb' package should be enough. If you're not, you'll need GTK (and Python bindings), Glade (and Python bindings), and MySQLdb (which is a Python binding). It may be a pain or even impossible to get Reptile running on Windows.
ReptileSQL is not ready for prime time just yet. If you want to help developing Reptile, you are invited to clone the GitHub repository: http://github.com/wandernauta/ReptileSQL/. If you don't care about development, you can grab a tarball here.
Conceived, built and tested on 
Ubuntu Linux
