• Test use of a apt.txt file.

r-rspm-description-file

• Test use of a DESCRIPTION file instead of an install.R file, where a runtime.txt is omitted and a recent enough snapshot date is assumed a RSPM snapshot of CRAN to be used.

r4.0-rspm

• Test setup of a R 4.0 environment by specifying r-4.0-... in runtime.txt, where the date provided in runtime.txt is recent enough for a RSPM snapshot of CRAN to be used.
