* This step creates foo.ism and foo.ismc that is required by IIS for
* serving it.
*
+ * By adding -path-prefix path/, the produced foo.ism will refer to the
+ * files foo.ismv as "path/foo.ismv" - the prefix for the generated ismc
+ * file can be set with the -ismc-prefix option similarly.
+ *
* To pre-split files for serving as static files by a web server without
* any extra server support, create the ismv file as above, and split it:
* 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.)
