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.
