## <NOTE>
## We need to update an ex_in file if it is older than any Rd file it
## contains examples from, or older than massage-Examples.pl.  As we do
## not have the Rd files as explicit dependencies (which would currently
## be impossible for recommended packages), we cannot use Make to figure
## out the need to update ex_in files ... hence we do things ourselves,
## and force these computations.
## The ugly 'find | grep' construct is necessary because 'test -nt' is
## not portable.  The pipeline will succeed if the target exists and is
## newer than the corresponding DESCRIPTION file in the package.  If the
## target does not exist, then find will fail; if it exists and is
## older, then find will succeed but output nothing so that the grep
## will fail.
