"shouted down", "shot down", apologies

Oh yeah -- one other thing.  Most maintainers use separate build and src 
trees.  I don't -- I build "my" packages right in the source directory. 
  However, you *MUST* use separate build and src trees for gcc, 
binutils, and cygwin -- or it won't work.  The "directions" below for 
readline assume the build-in-source-tree model.

I wonder if the following is a useful thing to have in the 
documentation: at set of build instructions (and nothin' but build 
instructions) for each package.  Say, a web page with a bunch of links 
to 10 line txt files (bash scripts?) that each build a given package.

I'm willing to provide that for "my" packages, if somebody else will 
handle the logistics -- and folks think it is a good idea.  (I shudder 
to consider the binutils, gcc, and cygwin scripts -- that python monster 
someone posted earlier today scared even me...)
