# BUILD_ENV_FILE_PHP=${buildDirectory}/buildproperties.php
# BUILD_ENV_FILE_PROP=${buildDirectory}/buildproperties.properties

# Note we always append to file, assuming if doesn't exist yet and will be
# created, and for each build, it won't exist, so will be written fresh for
# each build.

# TODO: Could add some sanity checking of if variable name appropriate
# for various language (e.g. I forget all the rules, but bash variables
# can not start with numerial, PHP variables (or is it Ant) can't have hyphens
# (or is it underscore :), etc. But may need to add some mangling, or warning?
# Similarly, not sure at the moment of what to
# write if value is null/empty. For now will leave empty string, but some might need blank?
# Or literally nothing? Also, unsure of effects of full quoting or if always needed?
