Importing a quilt patch series into git is not very difficult
but parsing the patch descriptions and all of the other
minutia take a bit of effort to get right, so this automates it.
Since git and quilt complement each other it makes sense
to make it easy to go back and forth between the two.

+================
+
+NAME
+----
+git-quiltimport - Applies a quilt patchset onto the current branch
+
+
+SYNOPSIS
+--------
+[verse]
+'git-quiltimport' [--author <author>] [--patches <dir>]
+
+
+DESCRIPTION
+-----------
+Applies a quilt patchset onto the current git branch, preserving
+the patch boundaries, patch order, and patch descriptions present
+in the quilt patchset.
+
+For each patch the code attempts to extract the author from the
+patch description. If that fails it falls back to the author
+specified with --author. If the --author flag was not given
+the the author is recorded as unknown.
+
+The patch name is preserved as the 1 line subject in the git
+description.
+
+OPTIONS
+-------
+--author Author Name <Author Email>::
+ The author name and email address to use when no author
+ information can be found in the patch description.
+
+--patches <dir>::
+ The directory to find the quilt patches and the
+ quilt series file.
