================================================
Part 1 (adapted from [1] as modified by [2]):

The general idea of using an interchange format for electronic
documents is in the public domain. Anyone is free to devise a set
of unique data structures and operators that define an interchange
format for electronic documents. However, Adobe Systems
Incorporated owns the copyright for the particular data structures
and operators and the written specification constituting the
interchange format called the Portable Document Format. Thus, these
elements of the Portable Document Format may not be copied without
Adobe's permission.

Adobe will enforce its copyright. Adobe's intention is to maintain
the integrity of the Portable Document Format standard. This
enables the public to distinguish between the Portable Document
Format and other interchange formats for electronic documents.
However, Adobe desires to promote the use of the Portable Document
Format for information interchange among diverse products and
applications. Accordingly, Adobe gives anyone copyright permission,
subject to the conditions stated below, to:

* Prepare files whose content conforms to the Portable Document
Format

* Write drivers and applications that produce output represented in
the Portable Document Format

* Write software that accepts input in the form of the Portable
Document Format and displays, prints, or otherwise interprets
the contents

* Copy Adobe's copyrighted list of data structures and operators,
as well as the example code and PostScript language function
definitions in the written specification, to the extent
necessary to use the Portable Document Format for the purposes
above.

The conditions of such copyright permission are:

* Authors of software that accepts input in the form of the
Portable Document Format must make reasonable efforts to ensure
that the software they create respects the access permissions
and permissions controls listed in Table 3.20 of the PDF
Reference[1], to the extent that they are used in any particular
document. These access permissions express the rights that the
document's author has granted to users of the document. It is
the responsibility of Portable Document Format consuming
software to respect the author's intent.

* Anyone who uses the copyrighted list of data structures and
operators, as stated above, must include an appropriate
copyright notice.

This limited right to use the copyrighted list of data structures
and operators does not include the right to copy the PDF Reference,
other copyrighted material from Adobe, or the software in any of
Adobe's products that use the Portable Document Format, in whole or
in part, nor does it include the right to use any Adobe patents,
except as may be permitted by an official Adobe Patent
Clarification Notice [3].

Acrobat, Acrobat Capture, Adobe Reader, ePaper, the "Get Adobe
Reader" Web logo, the "Adobe PDF" Web logo, and all other
trademarks, service marks, and logos used by Adobe (the "Marks")
are the registered trademarks or trademarks of Adobe Systems
Incorporated in the United States and other countries. Nothing in
the PDF Reference is intended to grant you any right or license to
use the Marks for any purpose.

===================================================

applications.
