quote = " R is a language and environment for statistical computing  \
and graphics. It is a GNU project which is similar to the S language \
and environment which was developed at Bell Laboratories (formerly   \
AT&T, now Lucent Technologies) by John Chambers and colleagues. R    \
can be considered as a different implementation of S. There are      \
some important differences, but much code written for S runs         \
unaltered under R."
