I copied and  evaluated the describe-keymap function, but when I typed
M-x describe-keymap I got the following error:

save-current-buffer: Symbol’s function definition is void:
Info-make-manuals-xref

I couldn't find the definition of a function by that name in the file
you indicated, so I'm guessing there's some dependencies involved and
that I don't have.  Could you provide a version of this function which
works on current master without requiring these extra packages?

Thanks,
