How to get Custom Web Player Build Process to work? (sample/instructions fail for me)

QUESTION: How do you make a build a Custom Web Player HTML Page? (the sample and instructions posted under documentation don't seem to work!)

---- Here is what I did --------

I read the directions found here, and thought "this looks a bit hard": unity3d.com/support/documentation/Manual/Build%20Player%20Pipeline.html

So then I found the Sample package for building a custom web player HTML page here: http://unity3d.com/support/resources/assets/postprocessbuildplayer

After unzipping it and then importing it into my project to this location:

My Unity Project\Assets\Editor\PostprocessBuildPlayer My Unity Project\Assets\Editor\Web Player Files{more files}

Then, as instructed, I did a "Build" for "Web Player", and it did the same thing as always -- nothing custom. I then hand-edited some of the text inside file "Web Player Sample.html" to see if any of my edits were being applied -- and they weren't.

How do I force my project to start using the "PostprocessBuildPlayer" asset? How do I diagnose the reasons for this NOT working?

The example on the doc page you mentioned is in Perl, but you can use any other language if it's easier. The executable file must be called "PostprocessBuildPlayer" and be in the Assets/Editor folder of your Unity project (just use the New Folder command within Unity to create this). The script/program gets passed the pathname of the player file and a few other command line arguments that might be useful.

However, do you really need to do any of this? If you are embedding the player in some custom HTML, you don't need to post-process anything. You can just put your HTML file in the Unity project folder (ie, where the generated player and HTML file appear) and embed the player into it. Then, as long as its name is different from the automatically generated file, it won't get deleted each time you build the player. You can just reload the page from the browser to see the freshly-built version of the player after an update.
