is libtool a standalone tool these days?

[Marty Leisner]

I'm reading the autobook -- it discusses lines like:
address@hidden 10:22:47; libtool gcc -c hello.c 
mkdir .libs
gcc -c hello.c  -fPIC -DPIC -o .libs/hello.lo
gcc -c hello.c -o hello.o >/dev/null 2>&1
mv -f .libs/hello.lo hello.lo
(this is from libtool 1.4 on redhat 7.2)

But libtool 1.5 wants a --tag option (which isn't defined in the
documentation).
It seems to work if I specify --tag=foo

All the documentation seems to point that libtool can run standalone.
Is this correct?
