-Notes:
- * The input template is copied into a BLOB column of the workunit table and will substitute filenames,
-  and have download urls, signatures and other elements inserted into your provided template.
-  The total expanded BLOB cannot exceed 65,535 bytes.
-  This is enough for about 200 input files,
-  fewer if you use long file names are multiple download URLs.
-  If this isn't enough, you can use [FileCompression BOINC file compression] to zip several files into a single file reference for download,

-In general, you should not attempt to use more then 50 files in your output template.
-This is because the provided template will have upload URLs, and file names expanded, and signatures added to it.
-The total size of the result must remain under 65,535 bytes to fit in the xml_doc_in and xml_doc_out BLOBs in the result table.
-Your actual limit on number of files will depend upon the length of your job names, and upload URLs.

-Note that here "_in" and "_out" are both references to the output template.
-"_in" being when the task was created, and "_out" how it looked,
-with actual file sizes and checksums, at the time the task was returned.
