# Download all sources:

# Optional: At this point, we have all dependencies and sources downloaded, so we can disconnect this computer from the internet in order to verify that our build process is sane, deterministic and does not depend on any external resources.

# Build and install libraries:

relpipe_install lib-common lib-reader lib-writer lib-cli lib-xmlwriter

# Build and install tools:

# Load Bash completion scripts:
