A nix development machine

1. A development machine is a collection of compilers (curren build
environments) that allow to compile source into some form of
non-standard output.

2. Outputs are not necessarily packages used as part of the build
system.  If this is needed, build a wrapper.

3. All build environments should be isolated from each other, to be
able to work on multiple projects.
