# This provides functions for verbose output for debugging

# redirect output, unset to disable. use e.g. /dev/stdout to write into a file/device.
# use special setting "on" to echo the output - unlike above, doesn't violate sandbox.
# the test here is to enable people to export DEBUG_OUTPUT before running ebuild/emerge
# so that they won't have to edit debug.eclass anymore
#[ -n "$ECLASS_DEBUG_OUTPUT" ] || ECLASS_DEBUG_OUTPUT="on"

# used internally for output
# redirects output wherever's needed
# in the future might use e* from /etc/init.d/functions.sh if i feel like it
