 content::revision::check_dirs [ -max_results max_results ] \
    [ -max_checks max_checks ] [ -returnlist ] [ -prune ]

Defined in packages/acs-content-repository/tcl/content-revision-procs.tcl

Figure out, how many directories in the CR are empty, report them optionally or delete them optionally.

Switches:

-max_results (optional, defaults to "5000")

stop after having found so many empty directories

-max_checks (optional, defaults to "10000")
