Right, but it would be better to create a `dose-<ver>-opam.tar.gz` with these files included in it and publish that to OPAM instead.  The files in here should really be for OPAM-specific build patches, or else things rapidly become confusing for external packagers (e.g. the Debian or BSD teams packaging up an OPAM system port that depends on this library). I'll merge this in the meantime though...
