Version 1 of the patch, for discussion, but not to be applied. It
does work, but needs a lot more testing.
This removes all the psychopathic gettextify cruft, and replaces it
with a 99 line Makefile.am. A large win, I think.
The third patch implements gettext support in the OCaml tools.
The fourth patch is just for illustration. It shows the consequent
changes to libguestfs.pot and the po files.
Rich.
