     These are individually not hard to install on most systems, but one might be worried about having conflicting versions of Fortran compilers or CMake on one system.
     So to address that concern and also to just serve as a very simple way to get started, there's now a conda package that will automatically install the prerequisites for stdlib.
     So then once you get the stdlib source code from Github, you can build stdlib and run its test suite with either make or CMake.
-    Then when you isntall stdlib, you get not only a static or shared library but also a pkg-config file and a CMake package file, which makes it very simply to use stdlib in your own projects.
-    The ideal situation of course is to distribute stdlib as an fpm package, and while that's still a work in progres, there's been good progress on the fpm side of things.
