WISHLIST

o allow flags/switches on makepkg.bat so that one does not have to
  edit settings at the top of the file

o add a switch to makepkg for turning on and off the prebuild

o allow one to specify a library on makepkg other than ./library

o better documentation

o more testing

o test on NT/2000

o see if R will adopt any of this so that it can be eliminated
  from the batch files. In particular, if R were to look in
  ...\R for *.site files if it can find them in ...\R\rw...\etc
  then R_ENVIRON and R_PROFILE would not have to be set.  Also,
  if ...\R\library were to be checked after ...\R\rw...\library
  then R_LIBS would not have to be set simplifying some of these
  batch files.

o figure out how to not have command window briefly appear when 
  using Rgui.bat
