## The front-end shell script now (2000-08-02) also contains the version
## information.  As we keep this information outside configure (as
## otherwise developers would have to reconfigure and hence rebuild
## every day), we now first create 'R.sh' from 'R.sh.in' via configure,
## and then use sed to create the front end ('R.fe') which gets
## installed as 'R'.
