# Update: As of March 24th 2017 this script won't work. 
# The script at https://get.haskellstack.org/ is broken 
# because the binary of Stack 1.4 for ARM is missing from https://www.stackage.org/stack/ .
# You can still get the binary for Stack 1.3.2 from
# https://github.com/commercialhaskell/stack/releases/download/v1.3.2/stack-1.3.2-linux-arm.tar.gz
# and place it at $USR_LOCAL_BIN/stack in your system.
# Once Stack is installed you can proceed with the Install LLVM step

In response to a request on Reddit, I'm writing up my thoughts on PVP upper bounds. I'm putting this in a Gist since I don't want to start yet another debate on the matter, just provide some information to someone who asked for it. Please don't turn this into a flame war :)

For those unaware: the Package Versioning Policy is a set of recommendations covering how to give version numbers to your packages, and how to set upper and lower bounds on your dependencies.

I'll start by saying: I support completely with the PVP's recommendations on how to assign version numbers. While there are plenty of points in this design space, the PVP is an unobjectionable one, and consistency in the community is good. On multiple occasions, I have reached out to package authors to encourage compliance with this. (However, I've always done so privately, as opposed to a statement on Reddit, as I believe that to be a more likely route to successful convincing.)
