 We should work on merging the letor branch to trunk, to ensure it doesn't
 bitrot and get lost.

 To get an overview of changes on the letor branch, see
 https://github.com/xapian/xapian/compare/master...svn%2Fgsoc2011-parth

 Several things need to be done.  Initially, by parth:

  - add the letor/dir_contents file, so the build system works.

  - remove letor/svm.h; the installed svm.h should be used instead.

  - add the formulae to the docs/letor.rst file (in latex form, we can
 worry about making them display nicely later.

  - remove the include of letor.h from xapian.h, and add a comment to the
 top of letor.h to indicate that it is not part of the official stable API.

 At this point, parth can submit his code to google, and the gsoc project
 is finished.

 Then, by olly or me:

  - merge recent changes in trunk to the branch

  - add detection of libsvm.h to configure.ac

  - make the build skip letor if svm.h isn't available

  - anything else required to merge the branch to trunk

  - check that at least one buildbot is building the letor code.

 I've marked this as milestone 1.3.0 so it doesn't get forgotten, but
 consider that a soft milestone.
