### Quaddouble integration

Implement a wrapper for the quad double library (C++) available at http://www.cs.berkeley.edu/~yozo/ : http://sage.math.washington.edu/home/dfdeshom/custom/patches/qdrf-c-interface.txt

### Modifying Mercurial

There is a turorial here: http://sage.math.washington.edu:9001/ModifyingMercurial There is also a mercurial spkg with better error messages here: http://sage.math.washington.edu/home/dfdeshom/custom/hg-sage/mercurial-20070209.spkg

### Multiplication algorithm

A (slightly) faster multiplication algorithm of univariate polynomnials over R. Currently, this is known as _mul_fateman() in rings/polynomial_element.py but needs to be faster, probably through PARI or Pyrex

### RealLib inclusion

RealLib3 as an alternate source for computing real numbers.

RealLib vs MPFR:

RealLib should not be a replacementto MPFR. MPFR has its uses and is

faster than RealLib3

### Tweaking Hermes

Logging of sessions using mathml through hermes:

- Improve, add fonts to hermes
- The final goal is to be able to reproduce the entire documentation
- in mathmml format. This is currently possible if you hack up some missing
fonts and avoid to generate the table of contents. Quite a pain I'll post a link to the generated doc

- in mathmml format. This is currently possible if you hack up some missing

Logging of pictures in dvi and mathml logger.

- Possible, but slightly tricky (how do you include a jpeg file in a DVI file
- without converting it to an EPS file?).

### Doctest Status

Does each method have an example? Instead of checking by hand a handy script could be used. I have a script that does that: http://sage.math.washington.edu/home/dfdeshom/sage/devel/sage/doctest-status.py For example, here is the output for integer.pyx:
