Include another yaml file from within .travis.yml? -

with rubocop, have behavior possible in .rubocop.yml file:

inherit_from:     - path/to/some/other.yml 

and that's nice create shared rulesets. .travis.yml files?

does travis ci have .travis.yml keyword include eternal yml file?

i've read of various woes of using yaml inherent behaviors; inherit_from: seems rubocop specific keyword , handler. i'm not removing possibility can handled yaml itself, i'd rather use travis ci approach if there one. don't believe purely yaml related, not sure.

i've looked around same approach demonstrated .rubocop.yml .travis.yml see no definite answer on how this. possible?

how can 1 .travis.yml file included within another?
