Thanks.  I plan to tackle these on HEAD presently.

There is a lot more to a working parallel install in libtool than I had
realised, so we'll pull it from branch-2-0 entirely.

Using libtoolize to copy the versioned libtool macros into your project
tree, and then using ACLOCAL_AMFLAGS = -I m4 to m4_include them into
aclocal.m4.

For the sake of documenting this more clearly on HEAD, can you identify what
about the current wording is unclear?

Agreed.  I'm not sure how to fix this at the moment either :-(
But, first, let's concentrate of branch-2-0.

Cheers,
        Gary.
