>I've rewritten install(1) to include the following options:
>(1) -S -- Symlink are created instead of moving (copying) the file.
>(2) -t -- Preserve the timestamp of the source file on target file.
I'd like these options:
-T -- If source data == target data, then preserve target timestamp.
Otherwise do the same as -t.
This is useful for avoiding changing target timestamps that other things
depend on. E.g., for header files, the target timestamp should normally
be preserved if possible.
-F -- if source timestamp == target timestamp, then do nothing.
Otherwise do a full install and print a warning giving
the source and target timestamps.
This is useful for rerunning `make install' on a large tree soon after
you've done a full install. E.g., immediately after installing with
-t it would tell you if everything got installed with the correct
timestamps; immediately after installing with -T it would tell you if
there are too many or too old targets; a little later, after rebuilding
a few scattered targets, you might want to reinstall the whole tree
to avoid missing anything, and -F should be faster.
Perhaps there should be options:
--timestamp-greatest -- set target timestamp to max(source, target)
timestamps.
--timestamp-smallest -- if source data == target data, then set target
timestamp to min(source, target) timestamps.
Otherwise do the same as -t.
-n -- don't actually install, but print what would be done without -n.
