+
+Color planned buildings based on their suspend status. When enabled, this plugin
+will display a colored 'X' over suspended buildings. When run as a command, it
+can resume all suspended building jobs, allowing you to quickly recover if a
+bunch of jobs were suspended due to the workers getting scared off by wildlife
+or items temporarily blocking buildling sites.
+
+Usage::
