There are many scripts for various builds in the buildconfig folder. These are meant to be run from the project root directory, for example, to build the portable pypy build:

[user@localhost Tuxemon]$ buildconfig/build_pypy_portable_linux.sh

There will be a new directory called build, which will have the package if everything was successful.

WARNING! The build scripts are designed to be run in a dedicated VM. They will add and remove packages and could leave your OS in a bad state. You should not use them on your personal computer. Use in a vm or container.

With the exception of the lib folder which may have its own license, all code in this project is licenced under the GPLv3.
