NAME
dotogether.pl
USAGE
'./dotogether.pl ord1 ord2 ord3 ...'
PURPOSE
integrates all integrands for the specified order of epsilon as one function, instead of individually integrating different pole structures and numbers of integration variables separately. this is particularly useful when intermediate calculations produce large positive and negative outputs, which cancel to give a small final result. NB if specifying a negative order, this must be expressed as 'm1', instead of '-1'. OPTIONS to use a parameter file with a different name use option "-p paramfile" to specify a different directory to work in use option "-d workingdirectory"
