This package was installed in our emacs, on HP-UX. It is not (yet?) incorporated in mf-init.
This means that you have to add:
(require 'jde)On Sun, where we have 1.1 and a
faster environment, I don't control the version of emacs, which
doesn't thus fulfil the requirements of this package.
Of course, for the time being, you can edit from HP-UX, using
remote-compile to build on Helios. In this way, everything
works fine, apart for debugging...
