  I'm really replying to [2].  There, you wrote:

  Well, yes, I would.  In fact, I did.  Twice.  There's org.conman.env [1],
which is a module that just creates a table of all the environment
variables, no functions whatsoever.  Then there's org.conman.errno [2] which
is nothing more than a table of system defined errors (like EDOMAIN, ERANGE
etc.).
