Globally installed dependencies can be installed via:

bash install-deps

The self-contained Lua and Torch installations are performed via:

./install.sh

By default Torch will install LuaJIT 2.1. If you want other options, you can use the command:

# If a different version was installed, used ./clean.sh to clean it
TORCH_LUA_VERSION=LUA51 ./install.sh
TORCH_LUA_VERSION=LUA52 ./install.sh

To update your already installed distro to the latest master branch of torch/distro simply run:

./update.sh

To remove all the temporary compilation files you can run:

./clean.sh

To remove the installation run:

# Warning: this will remove your current installation
rm -rf ./install

You may also want to remove the torch-activate entry from your shell start-up script (~/.bashrc or ~/.profile).

You can test that all libraries are installed properly by running:

./test.sh

Tested on Ubuntu 14.04, CentOS/RHEL 6.3 and OSX
