[racket] 18 scribble-created files

Thanks, Matthew.  I have to rework McFly and my package release setup 
for the new package system soon, and I plan to work around the 18 files 
then.

I don't know that my plan is relevant to anyone else, but here it is:

* Make distributions (and packages?) include the documentation files 
however they're generated by the current release version of Racket at 
the time the package version is released.

* Host the package version distributions (with versions in URLs) on my 
Web site.  Probably URLs like 
"http://example.com/racket/<PACKAGENAME>/<VERSIONSTRING>/".

* Change how I make the Web home page for each package.  Currently, each 
home page is a verbatim copy the Scribble-produced files for the latest 
released version of the package.  How I plan to change this is, instead 
of using the Scribble-produced 18 files verbatim, a script will take 
only the generated `.html` file and any image files, and tweak the HTML 
slightly to fit into the Web site without all the dependencies.  That 
works around the 18 files bloat for me, although I have to do upfront 
work, and I might have to do maintenance work some of the times that a 
new Racket version changes the HTML.

* Change the package home page urls (e.g., 
"http://example.com/racket-charterm/") to fit within the same URL tree 
that serves the new package versions (e.g., 
"http://example.com/racket/charterm/").

Basically, I'm trying to get back to good-quality package version 
releases being quick&easy to do.  The overhead of additional upfront and 
ongoing maintenance work on tools is not entirely consistent with 
quick&easy productivity on the packages, but hopefully I'll find time 
around Christmas.
