The prefered method for using Tubes API is to put a dev version jar on the build path and just reference it.
If you need to include source code from Tubes, please only include exactly which files you need.

If you wish to contribute a language please use the en_US.lang file in the assets/lang directory as the base for translations
Once you have finished a translation please submit a Pull Request. Please remember to use UTF-8 encoding on language files.
Make sure you have python installed and available on the system PATH.
Run "gradlew build" from a terminal/command prompt. The output will be in build/libs
