# python3 and python3-pip are added for Python 3 and its package installer.
# patchelf, bc, libelf-dev, flex, bison, and curl are added as requested.

# This command will print the GLIBC version when the container starts or when run manually.
# It's commented out by default but useful for debugging.

# The project source code will be mounted into this directory by GitHub Actions.

# The Docker image is now ready. The actual build commands will be run by GitHub Actions
