Actually, it is one (sort of), but it is broken. The instructions say
that you can use R CMD INSTALL to install in R < 2.0.0 (!) With a
current R, you can try but it dies:

No man pages found in package 'nls2'
** building package indices ...
Warning in file(file, "r", encoding = encoding) :
  cannot open file '../R/init.R', reason 'No such file or directory'
Error in file(file, "r", encoding = encoding) : unable to open connection
Calls: <Anonymous> ... switch -> sys.source -> eval -> eval -> source ->
Execution halted
ERROR: installing package indices failed
** Removing '/home/bs/pd/Rlibrary/nls2'

...and there were some odd goings-on at the start as well.
