Thanks Richard - I sort of realized that - and your comments basically
mirror those of the reviewers. On the other hand I quite like the idea of
RK formulas developed by CAS, in which there is a small literature. One
possible approach might be to use Sage also to generate the RK formulas

thanks for reporting this.
The fix is easy:

Hello,
There is often a "check" argument which is set to True by default.
class MyClass:
def __init__(self, data, check=True):
# 1. initialize the data
# 2. perform check
if check:
# potentially lengthy verification

This might be of general interest, even if this specific example is just

That might be because source filesystem has acl's enabled and target fs

Dear all,
I wanted to install the Latte package but the configure stopped with

GMP version 3.1.1 or greater is required for LattE to compile. Please
make sure GMP is installed and specify its location with the o

You received this message because you are subscribed to the Google Groups

This could have some relation with http://trac.sagemath.org/ticket/15635,
maybe.
