# - Use "return" instead of "exit" to signal a failure. Since this

# - All environment variables set here should be *exported*, otherwise
# they won't be available in child programs.

# If you want to set all environment variables for your shell like
# they are during the build of Sage packages, type

# sage --buildsh
