# Environment for recording the borg 1.4 demo screencast, see README.rst.
#
# Do NOT run the demo scripts outside of this container (or a VM): they install
# borg, create users, mount filesystems and write to /media.
#
# Build and run it via ./record.sh - it exports the borg sources from git and
# puts them into the build context as borg-src.tar.
