% output:

%      v: a string denotes the current version number; the string is
%       typically in the following format: "major.minor.patch-extra"
%       where major/minor/patch are typically integers, and extra can
%       be an arbitrary string and is optional
%    if you ask for 4 outputs:
%     [major,minor,patchnum,extra] are each field of the version string
