# Set environment variables for building and/or running Sage.
#
# NOTES:
# - You must *source* this script instead of executing.
# - Use "return" instead of "exit" to signal a failure. Since this
# file is sourced, an "exit" here will actually exit src/bin/sage,
# which is probably not intended.
# - All environment variables set here should be *exported*, otherwise
# they won't be available in child programs.
# - This script has a version number such that a newer version of
# sage-env can be sourced when upgrading. See below.
#
# If you want to set all environment variables for your shell like
# they are during the build of Sage packages, type
#
# . src/bin/sage-env
#
# from the SAGE_ROOT directory.
