@jbrands I will now merge this and prepare the corresponding PR for CMSDIST for the branch 8_1_X.

[ahinzmann]

@Degano : Could you make a version of this for all 76X, 80X and 81X.
The reason is that this will be used for an analysis recipes in 76X and 80X as well.

@ahinzmann The tests are now running for 81X in cms-sw/cmsdist#2166, it can be backported when it'll be integrated.

[ahinzmann]

Thanks you!

We need 80X and 76X versions of this.
I mentioned 80X in the ORP yesterday, although only verbally.
@Degano please clarify if you can make these.

[slava77]

@slava77 Sure I'll make the PRs now.
