Comment:

 I thought I'd post some work in progress for all the Bessel function fans
 in the crowd. There is still work to be done, e.g.

  * getting symbolic integration via Maxima to work
  * adding maxima, scipy, PARI, etc. to the implemented backend systems
  * more documentation and doctests

 but at this point the patch applies cleanly to 5.4.1 and all the doctests
 in `sage/functions/special.py` pass.

 If you are interested, have a look at the doctests included with the
 `Bessel` function for examples and let me know if you see any serious
 problems (other than the deficits I've listed above).

 Thanks!
