  * ismindex -split foo.ismv
  * This step creates a file Manifest and directories QualityLevel(...),
  * that can be read directly by a smooth streaming player.
+ *
+ * The -output dir option can be used to request that output files
+ * (both .ism/.ismc, or Manifest/QualityLevels* when splitting)
+ * should be written to this directory instead of in the current directory.
+ * (The directory itself isn't created if it doesn't already exist.)
