Portage offers fine-grained control over logging through the use of elog:
 * PORTAGE_ELOG_CLASSES: This is where users can define what kinds of messages to be logged. This can be any space-separated combination of info, warn, error, log, and qa.
 * info: Logs "einfo" messages printed by an ebuild
 * warn: Logs "ewarn" messages printed by an ebuild
 * error: Logs "eerror" messages printed by an ebuild
 * log: Logs the "elog" messages found in some ebuilds
 * qa: Logs the "QA Notice" messages printed by an ebuild
