Might this be added to the core functions?
Ben
How does that help you if we can't convince mathworks to do the
same?

Good point <blushing>
Perhaps an octave version of an existing Matlab function ("ver",
"version", "verLessThan", ?) could do the job?
Under matlab R2007b I see
a = ver('matlab')
a =
Name: 'MATLAB'
Version: '7.5'
Release: '(R2007b)'
Date: '02Aug2007'
a = ver('octave')
a =
0x0 struct array with fields:
Name
Version
Release
Date
The octave "ver" function doesn't take an argument. To get the
functionality you want this way you could modify Octave's ver so
that it
assumes the argument is 'octave' if it is missing and then something
like
if (strcmpi (pack, "octave"))
## Do what is already done, plus set ret if needed
else
lst = pkg("list");
ret = [];
for i = 1 : length (lst)
if (strcmpi (pack, lst{i}.name))
ret = struct ("Name", lst{i}.name, "Version", lst{i}.version,
"Release", [], "Date", lst{i}.date);
break;
endif
endfor
if (isempty (ret))
## How do you create an empty structure?
ret = struct ("Name", [], "Version", [], "Release", [], "Date",
[]);
ret(1) = [];
endif
endif
would get the type of behavior you want as long as someone doesn't
create an "octave" toolbox in matlab or a "matlab" package in octave.

That's a good start.
I'm busy for the next several hours, but will look more closely at how Matlab's version works and take a shot at this later today.
Ben
Ok, I've attached a diff respecting mercurial version, as well as the complete mfile.
Distinguishing between Matlab and Octave may be done as,
v = ver; if (strcmpi(v(1).Name,'matlab') % Matlab code here elseif (strcmpi(v(1).Name,'octave') % Octave code here end
