Below are some details regarding the design of Quezen.
Quezen is written in Java and uses the Standard Widget Toolkit (SWT) for its' UI. The current build of SWT that Quezen is using is 3.0.0.3062 for X86 and 3.0.0.3063 for X86_64 architectures so if you are compiling from source you will need this version on your machine.
At the moment Quezen only has an an English translation but the application itself has the plumbing to support other languages.
You will find language files in the conf directory. Each file is formatted as XML and represents a spoken language. You can point Quezen to a new language file in the Quezen | Options |Setup menu.
If you have a new language you would like to submit to the Quezen project then please email it to mogray@users.sourceforge.net
