  • Committer: Bazaar Package Importer
  • Author(s): Andres Salomon
  • Date: 2008-01-05 23:58:56 UTC
  • mfrom: (1.1.1 upstream)
  • Revision ID: james.westby@ubuntu.com-20080105235856-2kmxhxkz14qjy9ia
Tags: 3.5.0-1
* New upstream release.
* Add tcpp.dpatch.  This stops tests/stress/t.cpp from including
  ncbi_pch.hpp.  As far as I can tell, NCBI is not used at all, I have
  no idea where that came from..
* Silence some lintian warnings; binary-arch-rules-but-pkg-is-arch-indep
  and ancient-standards-version.
