Function to return relative path?

[Paul Merrell <marbux@...>]

Hi, all,

To avoid reinventing the wheel, I thought I'd ask whether anyone has a
function that will return a relative path from absolute paths for the
current and destination directories? Something along the lines of:

function(curdir, destdir)
  ...
  return reldir
end

I googled around but found only a function that has dependencies.[1]
