I intend to orphan the pyecm package. It is little-used (popcon score 19). The package description is: pyecm is a Python program to factor numbers using the Elliptic Curve Method (ECM). It is relatively fast in that it can quickly factors numbers up to 50 digits. . Because it is written in Python, pyecm is very portable. It is also fairly easy to use. Use of python-gmpy and/or python-psyco will speed it up immensely.
