Collecting possible questions about rang in this issue

1. Dry-running
2. Scanning a project for R packages (renv::dependencies)
3. Why is the R script generated by dockerize and export_rang so strange/unidiomatic/inefficient/did you guys read fortunes::fortune("answer is parse")? (Because we optimize for backward compatibility)
4. Why doesn't rang support R < 2.1.0? (Because installing source package from within R was introduced in R 2.1.0. Before that one need(s/ed) to install with R CMD INSTALL. But we are working on supporting R in the 1.x series.)
5. How should I back up a generated container to ensure maximum reproducibily?
6. How can I access the shell instead of R of the container?
7. How is this different to package x? (pkgdepends, groundhog, checkpoint, renv, remotes, Require, containerit, pak, miniCRAN...)
8. What are the caveats of using rang?

3. [v0.1.0rc] Why gran uses devtools instead of remotes? (Because devtools::install_github was introduced in 2011)

4. Why the R script generated by dockerize and export_granlist so strange/unidiomatic? (Because that's for backward compatibility)

How is this different to package x? probably need a sentence or two for all packages in #1
