Well, if you use aclocal, then it will cause the code from libtool.m4
to be included in aclocal.m4.  If you distribute libtool.m4 in your
package, then the inclusion will be a simple line
  m4_include([m4/libtool.m4])

(assuming that is the right relative file name), otherwise the whole
text will be copied in there.

It's usually a good idea to ship a copy of libtool.m4 to ease updating.
You can also use AC_CONFIG_MACRO_DIR([m4]) so that updates of the file
can be done automatically by `aclocal -I m4 --install' (or CVS Libtool's
`libtoolize --install').

Yes.  For CVS Libtool, you usually need
  argz.m4 libtool.m4 ltoptions.m4 ltsugar.m4 ltversion.m4 lt~obsolete.m4

but possibly also the others (if you use libltdl).  Either of the above
commands will install the right set of files for you.

Cheers,
Ralf
