Well,
Dear Sage-Devel,
I have four questions that I couldn't find addressed on "Producing New
Sage Packages" at

I can create my spkg with

Hi,
I just noticed that sage-3.4.2 -- at least on my laptop -- the favicon

Just FYI, Bressoud and Wagon's Computational Number Theory book has a
more elementary (and very readable) account of this type of formula -
starting with Legendre and going through Meissel and Lehmer, from
around page 130 to page 140 - including fairly explicit implementation
ideas.

Yeah, it was supposed to be a feature, but I agree that double click
to remove is easier and less error-prone. I will give it a few days to
see if anybody has good argument why we should keep it and if not I
will remove it.
I will also make undo for the last erased vertex.

Your GCC compiled code is a derived work and that (in my
understanding) is why there exists the so called "runtime exception"
to the GPL that covers this

Just for the record, it's often easier to do:
sage: latex.__module__
'sage.misc.latex'

I disagree. A jpeg or .doc file is not source code in any sense of
the word, thus the GPL is completely irrele
The "Clarification of Sage and GPL" thread reminded me of something I've
noticed: in Sage library files, I often see this license statement:

Fidel,
I needed to handle this for the (experimental) patch at
http://trac.sagemath.org/sage_trac/ticket/5975
Someone can correct me on the finer points of this, but there is now a
global object named latex, which is an instance of the Latex class.
So the construction latex(u) can be changed to

Ondrej,
Caveat: my understanding of US copyright law and software licenses.
When you create something (book, photo, program) you automatically
have a copyright in/on that work. You may control the creation of
copies. With a GPL/GFDL license you explicitly grant others further
freedoms - someon

Then I think you think the GPL is silly and I agree with you :-)

Well... since Ond
Alfredo,
now that I have my space, it would be really nice to cross links
between accounts so people can choose the option that fits
the best for them.
Not to mention is also because we are part of the same. I'm not
sure how to post a link to your webpage, otherwise I'll have done it.
