Update documentation to state that we target linux systems about rtretrievalframework HOT 1 OPEN

From Mike

Peter,

Yes, the software is written and regularly tested on a variety of linux systems. We have built on the MacOS in the past, but it has been a while and isn't officially supported. Thanks for pointing this out, that is a pretty basic thing for us to have left out of the documentation. I filed a git issue for this.

I'd recommend George look at the user guide build directions at https://nasa.github.io/RtRetrievalFrameworkDoc/compilation.html#building, this is the documentation for a user just building the system. The documentation he was looking at is really for developers (i.e., how do you interact with the build system if you are adding new files or something like that). There users guide describes a single script "./nonjpl_build.script" which should work for building the system - this is a good place to start.

Our development system is Centos 6, we also regularly test on Fedora and Ubuntu. I'd expect the software can be built on pretty much any linux system with the required dependencies.

Either I or James McDuffie (CCed on this email) would be happy to answer questions.

How important is the MacOS support? Is this just a nice to have, or something that you particularly need? James has some fraction of burden money to support the retrieval framework, and adding back in and regularly testing for MacOS support might be something to add if there is a need for this - we had just dropped this over time as a low priority at JPL since we generally run on linux.
