+Usage: perl delete_builds.pl dir1 [dir2 ...]
+
+Delete one or more builds, making free space as quickly as possible
+by deleting a few selected directories first
+
+You can use wildcards in the directory names, and they can be either
+individual builds or directories of builds. A build is identified by
+the present of an "output" subdirectory.
