Feature request : multiple build configurations

[alanz]

At the moment there is no way to override the stack.yaml config file for a project.

Certain packages need to support multiple compiler versions, and it would be useful to be able to run a stack test against each of these in turn.

Perhaps provide a command line flag to specify the particular stack.yaml to be used for a given operation.

Alternatively the stack.yaml format could support multiple configurations, but I think that would be unnecessarily complex.

Current context

Version 0.1.0.0, Git revision 67893a83d55810f2592c0073bae51aeaff14f142

There's already support for a STACK_YAML environment variable to choose an alternate config file. Issue #378 is tracking making that a command line option as well.

Ok, sorry. I scanned over the issues before posting but missed that.

No problem. If you have an idea of a way to make it more prominent in the docs, that would be great.

I think having a --stack-yaml command line option will document it
sufficiently.
