Q on License of mmcli

[Makoto Harada]

Dear ModemManager/mmcli maintainer 

We are now doing the feasibility study for ModemManager and mmcli,
and we have one question in terms of license.

---------
Question
--------- 
  Which license is intended to apply to mmcli ?
  "GPL v2 or later " or "GPL v3 or later" ? 

We know that source code of ModemManager is distributed under the "GPL 
v2 or later" license. 

When checking the header of the mmcli.c, the license is "GPL v3 or later",
but print_version_and_exit() in the same file is saying that it's "GPL v2 or later".

So, we would like to clarify this point.
