It's helpful only if you have a basic recipe, which requires only internal editing of the recipe, like stylesheets, fonts, etc.
When running a recipe inside Calibre, there are only two types of recipes - those that need a user/password and those that don't. You can't pass anything to the recipe other than the user/password combo. His batch file works for those that do not need the user/password.
It's true that you can provide some other parameters to the recipe on the command line, but for general purpose testing, the only two I ever use are the same two he's hard-coded into the batch file "-vv" to get the verbose output and "--test" to limit the number of feeds and articles retrieved from each feed.
Basically, his batch file is identical to the one I use on every recipe I test except that he didn't send error output to a file. I use that same batch file even for recipes that need user/password, but I modify the recipe internally during the testing stage with a hardcoded user/password, then remove it before sending it to Kovid. His batch file essentially replicates the recommendation in the user manual here: http://calibre-ebook.com/user_manual...ght=recipe#id9
