Hello Emacs

Please consider the following package for future inclusion.  (Some years
ago I signed the GNU paperwork.)

This library provides links of symbols (functions, variables, faces)
within Emacs' Info viewer to their help documentation.  This linking is
done, when the symbol names in the texinfo document are:

1. Quoted symbol names like `quoted-symbol' or:

2. Function names are prefixed by M-x, for example "M-x
function-name" or are quoted and prefixed like "`M-x
function-name'".

3. Function names are behind the following forms in the Elisp manual:

  -- Special Form:
  -- Command:
  -- Function:
  -- Macro:

4. Variables names are behind the following text:

  -- User Option:
  -- Variable:

In any case all symbol names must be known to Emacs, i.e. their names
are found in the variable `obarray'.

You can follow the additional links with the usual Info keybindings.
The customisation variable `mouse-1-click-follows-link' is influencing
the clicking behavior (and the tooltips) of the links, the variable's
default is 450 (milli seconds) setting it to nil means only clicking
with mouse-2 is following the link (hint: Drew Adams).

The code uses mostly mechanisms from GNU-Emacs' lisp/help-mode.el file.
