Hello,

I set up some rake tasks to generate documentation for my rails app. I
started with the doc:app task from rails and the rdoctask in rake
definitions. I'm learning rake so please go easy on me.  ;-) Here is what I
came up with:

desc "Generate API Documentation"
SRC =3D
FileList['doc/README_FOR_APP','doc/REQUIREMENTS','doc/DESIGN','app/**/*.rb'=
]
file "doc/app/index.html" =3D> SRC do
  rm Dir.glob('doc/app/**/*.html')
  require 'rdoc/rdoc'
  options =3D []
  options << "-o" << 'doc/app'
  options << "--title" << "Goals System"
  RDoc::RDoc.new.document( options+SRC )
end

task :gendocs =3D> "doc/app/index.html"

desc "Clobber API Documentation"
task :clobberdocs do
  rm Dir.glob('doc/app/**/*.html')
end


When I do

 rake --trace gendocs

It appears the documentation is generated, then deleted, then generated
again.

???

That's my question -- why does it generate, delete, and then generate it
again.


Additional background:

I'm trying to address 2 problems:

   1. I want to include doc/REQUIREMENTS, and doc/DESIGN in my rdoc run.
   2. We have a policy here of saving generated documentation in cvs. The
   rdoctask that comes with rake does a rm_r, deleting everything in the ta=
rget
   directory including .CVS files. This makes it difficult to do a commit t=
o
   cvs.

Thank you.

-Kelly
