littler binary package in Ubuntu Jammy armhf

 The 'r' (aka 'littler') program provides a lightweight binary wrapper around
 the GNU R language and environment for statistical computing and graphics.
 .
 While R can be used in batch mode, the r binary adds full support for
 both 'shebang'-style scripting (i.e. using a hashmark-exclamation-path
 expression as the first line in scripts) as well as command-line use in
 standard Unix pipelines. In other words, r provides the R language without
 the environment.
 .
 This virtual package ensures that 'r-cran-littler' is installed. Once that
 is done, this 'littler' package can be removed.
