# Save the work directory for a recipe when one of its tasks fails.
# Useful in cases where the environment in which builds are run is
# ephemeral or otherwise inaccessible for examination during
# debugging.
#
# To enable, simply add the following to your configuration:
#
# INHERIT += "workdir_save"
#
# Notes:
# * For this to work you also need corresponding logic in your build
# orchestration tool to pick up any files written out to WORKDIR_SAVE_DIR
# (with the other assumption being that no files are present there at
# the start of the build).
# * Work directories can be quite large, so saving them can take some time
# and of course space.
