what's the proper way to determine emacs version?
i use this code:
(if (string= (substring-no-properties emacs-version 0 2) "23" )
; is 23
; not 23
)
is there more robust way?
thanks.

Variables emacs-major-version and emacs-minor-version. They contain an
integer.
But if you need to check if some feature exists in the system you'd
better check precisely that. For example, check the existence of some
function with (fboundp ...).
