# Tomb1Main building toolchain for Linux.
#
# This is a multi-stage Docker image. It is designed to keep the final image
# size low. Each stage builds an external dependency. The final stage takes the
# artifacts (binaries, includes etc.) from previous stages and installs all the
# tools necessary to build Tomb1Main.
