Extended (ck*).

The command now prompts the composer to supply missing directories and files
across all packages checked.

Example:

    Score Manager - segments (example scores)

       1: segment 01 (Blue Example Score)
       2: segment 02 (Blue Example Score)
       3: A (Red Example Score)
       4: B (Red Example Score)
       5: C (Red Example Score)

          segments - copy (cp)
          segments - new (new)
          segments - remove (rm)
          segments - rename (ren)
