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:

     contents of a file containing Original Code or

     previous Modifications.

     B. Any new file that contains any part 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,
