[racket-dev] proposal: `data' collection

There's no reason to do that -- the data is all there in the dep
files.  It just needs to be trimmed for the collection name instead of
the full paths.

I'm attaching a file with a list of all toplevel collections and a has
table that maps collection names to what they depend on.  I tried to
visualize this with graphviz in a number of ways -- and there was
nothing that producing a graph that would make sense.  I then wrote
some code and there's two groups of collections -- one huge ball of
code that is all inter-dependent, and then a bunch of collections that
are nearly free of dependency problems.  The only problem in the
latter group is teachpacks and deinprogramm which form a cycle.

So, the unproblematic set of collects is:

  2htdp, afm, algol60, combinator-parser, datalog, defaults,
  embedded-gui, eopl, frtime, gui-debugger, guibuilder, handin-client,
  handin-server, hierlist, honu, lazy, macro-debugger, make, mysterx,
  mzcom, plai, plot, preprocessor, racklog, redex, repo-time-stamp,
  schemeunit, sgl, sirmail, slatex, srpersist, swindle,
  test-box-recovery, tex2page, waterworld, games, tests, meta

it would work fine to install them one by one in this order, except
for {teachpack, deinprogramm} which are their own set.

The problematic set of collects is:

  racket, at-exp, browser, compiler, config, drracket, drscheme,
  dynext, errortrace, ffi, file, framework, graphics, help, htdp,
  html, icons, lang, launcher, mred, mrlib, mzlib, mzscheme, net,
  openssl, parser-tools, planet, profile, r5rs, r6rs, rackunit, raco,
  reader, readline, rnrs, s-exp, scheme, scribble, scribblings,
  scriblib, setup, slideshow, srfi, stepper, string-constants, syntax,
  syntax-color, test-engine, texpict, trace, typed, typed-scheme,
  unstable, version, web-server, wxme, xml
