I released a new cleaned up version of the gdiff / gpatch library and
programs. Now available as a gem and in setup.rb format.

Find it at

  http://ruby.brian-schroeder.de/gdiff/

Installation:

  wget http://ruby.brian-schroeder.de/gdiff/releases/gdiff-0.0.1.tar.bz2
  tar -xvvjf gdiff-0.0.1.tar.bz2
  cd gdiff-0.0.1
  ruby setup.rb

Usage:

  gdiff file_a file_b > patch
  gpatch file_a patch > file_b_from_patch

or as a library:

  require 'gdiff'

  File.open("patch", "wb") do | patch |
    patch << Diff::GDiff.diff(File.read("file_a"), File.read("file_b")).pack
  end

  File.open("file_b_from_patch", "wb") do | file_b_2 |
    file_b_2 <<
Diff::GDiff.unpack(File.read("patch")).apply_to(File.read("file_a"))
  end

regard,

Brian

Cool stuff.  I swear someday I have to get back into the fastcst
thing.  I just have so much crap to do it's killing me.

Let me know if you run into any bugs in the suffix array delta library.

I already wrote you directly, but maybe I used the wrong address. So
I'd like to ask you here in public if it is legal under the suffix
array library licence and acceptable to you to publish this work using
the ruby licence?
And I have included your sourcecode including the README, LICENCE and
COPYING file ripped from the fastcst tarball directly in this release.
Is that ok?

cheers,

Brian
