+uname -s is used to determine the differences between the command line
+utilities like stat or awk in linux and darwin. However, in nix, guilt
+will be using the nix versions of this programs, not the ones
+installed in the system.  Therefore, guilt should use the command-line
+parameters that the linux forms of these commands expect, even if it
+is being run on Darwin.

+      Andrew Morton originally developed a set of scripts for
+      maintaining kernel patches outside of any SCM tool. Others
+      extended these into a suite called quilt]. The basic idea behind
+      quilt is to maintain patches instead of maintaining source
+      files. Patches can be added, removed or reordered, and they can
+      be refreshed as you fix bugs or update to a new base
+      revision. quilt is very powerful, but it is not integrated with
+      the underlying SCM tools. This makes it difficult to visualize
+      your changes.
+
+      Guilt allows one to use quilt functionality on top of a Git
+      repository. Changes are maintained as patches which are
+      committed into Git. Commits can be removed or reordered, and the
+      underlying patch can be refreshed based on changes made in the
+      working directory. The patch directory can also be placed under
+      revision control, so you can have a separate history of changes
+      made to your patches.
