1. DEFINITIONS
 
1.1. \"Contributor\" means each entity that creates or
contributes to the creation of Modifications.
 
1.2. \"Contributor Version\" means the combination of the
Original Code, prior Modifications used by a
Contributor, and the Modifications made by that
particular Contributor.
 
1.3. \"Covered Code\" means the Original Code or
Modifications or the combination of the Original Code
and Modifications, in each case including portions
thereof.
 
1.4. \"Electronic Distribution Mechanism\" means a
mechanism generally accepted in the software development
community for the electronic transfer of data.
 
1.5. \"Executable\" means Covered Code in any form other
than Source Code.
1.6. \"Initial Developer\" means the individual or entity
identified as the Initial Developer in the Source Code
notice required by Exhibit A.
 
1.7. \"Larger Work\" means a work which combines Covered
Code or portions thereof with code not governed by the
terms of this License.
 
1.8. \"License\" means this document.
 
1.9. \"Modifications\" means any addition to or deletion
from the substance or structure of either the Original
Code or any previous Modifications. When Covered Code is
released as a series of files, a Modification is:
 
     A. Any addition to or deletion from the
     contents of a file containing Original Code or
     previous Modifications.
 
     B. Any new file that contains any part of the
     Original Code or previous Modifications.
 
1.10. \"Original Code\" means Source Code of computer

which, at the time of its release under this License is
not already Covered Code governed by this License.
 
1.11. \"Source Code\" means the preferred form of the
Covered Code for making modifications to it, including
all modules it contains, plus any associated interface
definition files, scripts used to control compilation
and installation of an Executable, or a list of source
code differential comparisons against either the
Original Code or another well known, available Covered
Code of the Contributor's choice. The Source Code can be
in a compressed or archival form, provided the
appropriate decompression or de-archiving software is
widely available for no charge.
 
1.12. \"You\" means an individual or a legal entity
exercising rights under, and complying with all of the
terms of, this License or a future version of this
License issued under Section 6.1. For legal entities,
