Where's the HXML docs?

I've looked all over the Haxe Flash Command-line compiler website but was unable to find any detailed documentation of the HXML files (scroll down to the "Changing SWF properties" section) which describe the compile.

Anybody know of a reference source?

Found HXML:

• -swf MyApp.swf .... Compile to SWF
• -main MyAppClass .... Entry-point Class (.AS file)
• -swf-header 200:300:25:FFFFFF .... Width:Height:FPS:BackColor (of SWF)

Edit: Scroll down for my answer with the complete list of commands.

Have you tried:

haxe --help

.hxml files are just a convenient way to pass commandline parameters as far as I know.
