I like the overall idea of this RFC, but I'm not wild about this specific word "print" -- it seems weird. All the MCA parameters are *printed* -- the word "print" doesn't really distinguish anything here.

(I know I'm just harping on a word, but I think it's an important word here... :-) )

Got a better suggestion, perchance? (I don't, offhand...)

How about changing this a bit (hoping my regexp syntax is correct at 6:30am before coffee...):

ompi_info --all --parsable | egrep ':(compile|run)time_version'

Then the "print_" prefix isn't needed.
