# This provides functions for verbose output for debugging

# Note: we check whether these settings are set by "if [ "$FOO" ]; then".
# Therefore set them to true/false only - not yes/no or whatever.

# redirect output, unset to disable
# use e.g. /dev/stdout.
# todo: add support for logging into a file.
# 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=""

# 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
