Hi,
is anybody willing to review
#13649<http://trac.sagemath.org/sage_trac/ticket/13649>?
It consists of implementing two/three new methods which are actually
aliases for existing methods, so it's quite easy to check if it's correct
or not.
Thank you, best regards.

No, PPAs contain binaries and also the corresponding sources, you have to
successfully build a package in order to upload it to the PPA for other
people to download it.
