Documentation
Display the version of Emacs that is running in this session.
With a prefix argument, insert the Emacs version string at point instead of displaying it. If called from Lisp, by default return the version string; but if the optional argument HERE is non-nil, insert the string at point instead.
Don't use this function in programs to choose actions according
to the system configuration; look at system-configuration instead.
Probably introduced at or before Emacs version 19.1.
