ENiGMA½ will be installed to ${ENIGMA_INSTALL_DIR}, from source ${ENIGMA_SOURCE}.
ENiGMA½ requires Node, v${ENIGMA_NODE_VERSION} will be installed via nvm. If you already have nvm installed, this install script will update it to the latest version.

If this isn't what you were expecting, hit ctrl-c now. Installation will continue in ${WAIT_BEFORE_INSTALL} seconds...
