+		Get a list of archivable histories based on user and history age.
+
+		    $ gxadmin query archivable-histories
+		    ...
+
+		The --size option can be used to show the size of the histories returned, but can significantly slow the
+		query.
+
+		One useful way to use this function is like so:
+
+		    $ gxadmin tsvquery archivable-histories --size | \\
+		        awk -F'\\t' '{print \$1; sum+=\$NF;} END {print "Total: " sum/1024^3 " GB" > "/dev/stderr";}' | \\
+			GALAXY_CONFIG_FILE=/gx/config/galaxy.yml xargs /gx/venv/bin/python3 | \\
+			  /gx/galaxy/scripts/secret_decoder_ring.py encode
+
+		This outputs the total size to archive to stderr while encoding all history IDs on stdout for
+		consumption by API-based archival tools.
