[Haskell-cafe] Picking up the CI buildnumber during build

[Magnus Therning]

I'm looking for a way to pick up the CI buildnumber from the 
environment
(e.g. $TRAVIS_BUILD_NUMBER) and use it as part of of the output of
`my-tool --version`. I don't really know where to start looking, 
so I'm
hoping someone on the list has already done something similar and 
can
point me to a working example :)

I am always doing that which I cannot do, in order that I may 
learn
how to do it.
