Subject: * Doxyfile.in: new file. Template of a configuration file for  
 Doxygen.   Intorduces C-level API reference generation with Doxygen.

* tool/file2lastrev.rb: wrapper script that abstracts subversion
  and git-svn.

* tool/strip-rdoc.rb: filter for preventing doxygen from processing
  rdoc comments.

* configure.in: (Doxyfile): Doxyfile is generated together with
  Makefile.
  (PACKAGE): configuration $(PACKAGE) is necessary for $(docdir).

* instruby.rb: adds a new install target 'capi'

* common.mk (capi): new target that generates C API documents with
  Doxygen.
  (install-capi): new target.
  (pre-install-capi): ditto.
  (do-install-capi): ditto.
  (post-install-capi): ditto.
