PERL module to create Blu-Ray ISOs

The script will be given an input path to a directory with numbered subdirectories (e.g. 001): 1. Calculate the size of each subdirectory and confirm that each will fit on a Blu-Ray disk. a. If a subdirectory is too large, rename it to signify the error (e.g. 001_err). 2. Create an ISO (ISO9660+UDF) for each non-error subdirectory that will mirror the name of the subdirectory (e.g. 001). The ISOs will be created in an output path also provided to the script. Ideally, the script would use only CPAN modules, but we are willing to consider the use of additional freeware modules if recommended by the developers. Script must run on Windows 7.
