-Description: Provides helper functions to create reproducible development

+Description: Simplifies the creation of reproducible development environments
+    using the 'Nix' package manager. The included `rix()` function generates a
+    complete description of the development environment as a `default.nix` file,
+    which can then be built using `Nix'. This results in project specific 
+    software environments with pinned versions of R, packages, linked system
+    dependencies, and other tools. Additional helpers make it easy to run R code
+    in 'Nix' software environments for testing and production.

+quotes: "Title")
+
+We added a reference to a paper describing Nix.

+- Please ensure that your functions do not write by default or in your
+examples/vignettes/tests in the user's home filespace (including the
+package directory and getwd()). This is not allowed by CRAN policies.
+Please omit any default path in writing functions. In your

+Regarding functions `rix()` and `rix_init()`: we don't set `project_path` to
+`"."` by default anymore.
