I don't like to assume the existence of IPython for portability
reasons, so I usually just use something like
err = os.system('mv tmp0-50/output-02*.png some-other-directory')
A little more to type I guess, but safer I think.

I would like to see in $SAGE_ROOT:
README.txt
README-OSX.txt (instead of sage-README-OSX.txt)
README-Linux.txt
README-Solaris.txt
README-Windows.txt
...
Then we could separate the generic information from system-specific ones.
Also, all $SAGE_ROOT/*.txt files have to move from the sage_scripts

Python 2's division for integers is also quite unsuitable for a
computer algebra system:

But Sage fixes this:

Just FYI - that file is NOT a normal README, but rather a README that
gets copied when we create a dmg disk image when bdisting Sage on
Mac. It should

True - so find someplace else for it that doesn't clutter up
$SAGE_ROOT and change sage-bdist appropriately :)
I guess it could even go in extcode along with the other stuff for the

Hi there,
In combinatorics, we very often use the set of non negative integers. It is
currently implemented in sage as NonNegativeIntegers(). Note that it is only a
facade parent, that is element it generate are plain standard sage Integer
with parent ZZ. We'd like to have it standard in the
An alternative would be to make standard Python functions (such as
count) return Integer objects, but this would make it incompatible
with vanilla Python.

What more than the following are you proposing?
sage: version()
'Sage Version 4.6.2.alpha0, Release Date: 2011-01-13'
sage: NN
Non negative integer semiring
sage: latex(NN)

Ok, but this readme is not a readme, if you catch my drift. It's a
readme we definitely don't want anyone reading, except when it's
bdisted into a dmg top-level directory (above $SAGE_ROOT).

I wonder if it is possible to use setjmp/longjmp in order to return to
a place in a Cython function (within Sage) from a dynamically loaded
library written in C.
(this would be a way to handle exceptions in GAP interpreter in libGAP
(see #6391))

I'm trying to build 4.6.2.alpha1 on Skynet's "mark" (Solaris SPARC) and

did the build fail, even though iconv was installed correctly?
