License. 'MobileSpaces', below, refers to any such program or work, and
a 'work based on 'MobileSpaces' means either MobileSpaces or any work
containing MobileSpaces or a portion of it, either verbatim or with
modifications. Each licensee is addressed as 'you'.

Ichiro Satoh grants to you ("Licensee") a nontransferable,
nonexclusive, royalty-free, limited license to use a copy of
MobileSpaces for internal evaluation, research and educational purposes
only, including the right to modify the MobileSpaces source code. Other
than the limited rights granted in this License, Licensee acquires no

code as you receive it, in any medium, provided that you conspicuously
and appropriately publish on each copy an appropriate copyright notice
and disclaimer of warranty; keep intact all the notices that refer to
this License and to the absence of any warranty; and give any other
recipients of MobileSpaces a copy of this license along with MobileSpaces.

You may modify your copy or copies of MobileSpaces or any portion of it
only for your own use. You may not distribute modified copies of
MobileSpaces. You may, however, distribute your modifications as
separate files (e.,g. patch files) along with the unmodified
MobileSpaces software. We also encourage users to send changes and
improvements which would benefit many other users to us so that all
users may receive these improvements in a later version. The
restriction not to distribute modified copies is also useful to
prevent bug reports from someone else's modifications.

except the cost for the media and a fair estimate of the costs of
computer time or network time directly attributable to the copying.

You may not copy, modify, sublicense, distribute or transfer
MobileSpaces except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, distribute or transfer
MobileSpaces is void, and will automatically terminate your rights to

copies, or rights to use copies, from you under this License will not
have their licenses terminated so long as such parties remain in full
compliance.

By copying, distributing or modifying MobileSpaces (or any work based on
MobileSpaces) you indicate your acceptance of this license to do so, and
all its terms and conditions.

Each time you redistribute MobileSpaces (or any work based on
MobileSpaces), the recipient automatically receives a license from the
original licensor to copy, distribute or modify MobileSpaces subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.

If Licensee desires that its use of the MobileSpaces software be for
commercial or productive use such as product development or product or
customer support, Licensee must execute a commercial license agreement
with Ichiro Satoh and Ochanomizu University.

Because MobileSpaces is licensed free of charge, there is no warranty
for MobileSpaces, to the extent permitted by applicable law. The
copyright holders and/or other parties provide MobileSpaces 'as is'

defective, you assume the cost of all necessary servicing, repair or

In no event will any copyright holder, or any other party who may

damages, including any general, special, incidental or consequential
damages arising out of the use or inability to use MobileSpaces
(including but not limited to loss of data or data being rendered
inaccurate or losses sustained by you or third parties or a failure of
MobileSpaces to operate with any other programs), even if such holder or
other party has been advised of the possibility of such damages.
