- Add rubber-makeinfo-unsupported-option.patch to fix building
on openSUSE <= 13.2, where makeinfo does not support the
"--info" option.

- Update to version 1.4:
+ New distutils-based build & install scripts by Nicolas.
+ Report BibTeX / Biber errors more reliably.
+ We have support for embedding R code via knitr.

Closes: https://bugs.launchpad.net/rubber/+bug/1422759
Note that since R can run arbitrary external code, --unsafe
must be given at the command line:
rubber -d --unsafe paper.Rtex
creates beautifully typeset PDF from your R script.
+ Support for PythonTeX package. Also requires --unsafe if
you want Rubber to invoke pythontex.
+ Rubber will no longer attempt to use jpeg2ps on its own, which
has been superseded by sam2p. (You can add it back by
providing your own rules.ini.)
+ More refactoring, reducing the number of code paths to test and
maintain.
+ Bugs fixed: lp#628150, lp#975376, lp#1090115.
- Also package HTML and PDF documentation in main package
(documentation files are rather small and do not warrant a
separate doc pkg).
- Drop conditionals and macro definitions for ancient distro
versions.
- Add BuildRequires: texinfo, required for building PDF
documentation.
