RE: Setting up a custom info node.

[Drew Adams]

Double apologies, if this doesn't respond to what you're looking for.

(1) I haven't really followed this thread and have no special help.
I'm not sure what you've already tried, but you should be able to simply replace
the `dir' file of your Emacs installation by your own `dir' file. Or if you
cannot do that (e.g. you have no access to that location), then you should be
able to change the value of your INFOPATH env variable (or
`Info-default-directory-list' Emacs variable, if INFOPATH is undefined) to
reference your own `dir' file, wherever it is. 

This assumes that you've created your own `dir' file to point to the Info
manuals you really want. So my suggestion would be: (a) set INFOPATH to point to
your chosen directory, where you put (b) your own customized `dir' file.

(2) This is off-topic from what you apparently really want (a customized `dir'),
but it responds somewhat to your Subject line, which mentions `node' instead of
`dir':

If you use Icicles, you can create a virtual Info book made up of any set of
Info nodes you like, from the same or different manuals. You can create any
number of such books, for different topics.
