Waiting for jenkins to finish but this PR is identical to #4131 (for 72X) and #4509 (71X; just reviewed).
I did check that I can run the new customise option with this PR.

[jpavel]

ping? The jenkins somehow did not arrive yet...

I'll sign off to avoid blocking the PR, would be good to see the jenkins as a matter of principle.
I tested c41514e on top of CMSSW_7_0_X_2014-07-04-1400. It compiles and the new customise option can be run. The new code is identical to the tested versions for other releases (see above) and does not affect the default running sequences.

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_0_X IBs unless changes (tests are also fine). @nclopezo, @ktf can you please take care of it?

[jpavel]

is there anything blocking merging of this PR?

[ktf]

Explicit approval in ORP, since 70X is a closed release. Stoyan gave the ok only 4 days ago so the subsequent ORP is today.

I see - thanks @ktf for the info!
