You can now translate ReText using Transifex!
We now have a Transifex project. You can translate not only the app itself, but also additional files like desktop file and mime files. Please update your translation.
See the Quick Start Guide for the list of dependencies.
Debian and Ubuntu users can install ReText using
apt-get install retext command.
If you don't have a SourceForge.net account, you can ask questions and report bugs at Launchpad.
