# Provision the environment for the BugSwarm reproducing pipeline.
# Tested on Ubuntu 16.04.

# Assumptions:
# 1. The user running this script has sudo privileges.
# 2. The operating system is Ubuntu 16.04.
# 3. The repository was cloned into the REPO_DIR directory. If that is not the case, update the REPO_DIR variable.

# Include common functions and constants.

# At this time, the script accepts one optional argument: a GitHub credential in the form '<username>:<token>'.

# Hack to make the script ask for sudo password before printing any steps.

# Cache Git credentials for convenience.
