[Rivet] compare-histos with multiple analysis and multiple MC data sets

[Eike von Seggern]

Hi Riveters,

I want to compare reference data with two different MC results. The
problem I have is that I have more than one analysis, so what I tried
is:

$ compare-histos PATH/TO/OPAL_1998_S3780481.aida MC1.aida MC2.aida
$ compare-histos PATH/TO/DELPHI_1996_S3430090.aida MC1.aida MC2.aida

But the second call overwrites the OPAL*.dat files from the first call.

So is there a more comfortable way than concatening the output of
aida2flat and building a new AIDA file with flat2aida to create a new
reference data file?

BTW: aida2flat exits with an error if more than one aida file is given.

Cheers
