What you edit vs. what other tools edit

Some parts of DESCRIPTION are automatically updated by the package development and documentation tools, e.g. devtools::document() or devtools::build() will add something like:

Roxygen: list(markdown = TRUE)
RoxygenNote: 7.2.1

More on that in Chapter 16.

• devtools::check() and R CMD check will complain if anything in DESCRIPTION is not proper.
• extensive management tool provided by {desc}
