5 # the purpose here is to let people upload their delegated credentials
6 # to a manifold/myslice infrastructure, without the need for having to
7 # install a separate tool; so duplicating this code is suboptimal in
8 # terms of code sharing but acceptable for hopefully easier use
10 # As of April 2013, manifold is moving from old-fashioned API known as
11 # v1, that offers an AddCredential API call, towards a new API v2 that
12 # manages credentials with the same set of Get/Update calls as other
15 # Since this code targets the future we favour v2, however in case
16 # this won't work the v1 way is attempted too
19 ## this for now points at demo.myslice.info, but sounds like a
20 ## better default for the long run
