Comment(by wdj):
I agree, this needs docstrings.
Installation of the spkg went fine on a macbook running 10.4.11. The patch
seemed to apply okay. sage -testall on 4.1.rc1 passed except for failures
in parallel/decorate (DeprecationWarning: os.popen2 is deprecated. ) and
interfaces/sage0 (which could not be replicated).
The examples given in the sage-devel email (below) seemed to work okay,
though I am not an expert on this stuff.
{{{
g=graphs.RandomGNP(10,.5)
p=MIP(max=True)
obj={}
for i in g.vertices():
obj["V"+str(i)]=1
p.setinteger("V"+str(i))
p.setobj(Constraint(obj,obj=True))
for (a,b,c) in g.edges():
obj={}
obj["V"+str(a)]=1
obj["V"+str(b)]=1
p.addconstraint(Constraint(obj,lt=1))
p.solve()
}}}
