Add APSL 2.0 license to the COPYING file.

There is only one file covered by this license:
net-snmp-5.5/agent/mibgroup/host/data_access/swrun_darwin.c

This file is not used on Linux at all, it's only present in source
tarball and net-snmp.src.rpm.

In addition, it's licensed under APSL 1.1, but it allows to relicense
the code to 'any subsequent version of this License published by Apple'.
According to http://fedoraproject.org/wiki/Licensing, APSL ver. 2.0 is
better for us.

+Please read this License carefully before downloading this software.  By
+downloading or using this software, you are agreeing to be bound by the terms
+of this License.  If you do not or cannot agree to the terms of this License,
+please do not download or use the software.
+
+Apple Note:  In January 2007, Apple changed its corporate name from "Apple
+Computer, Inc." to "Apple Inc."  This change has been reflected below and
+copyright years updated, but no other changes have been made to the APSL 2.0.
+
+1.	General; Definitions.  This License applies to any program or other
+work which Apple Inc. ("Apple") makes publicly available and which contains a
+notice placed by Apple identifying such program or work as "Original Code" and
+stating that it is subject to the terms of this Apple Public Source License
+version 2.0 ("License").  As used in this License:
+
+1.1	 "Applicable Patent Rights" mean:  (a) in the case where Apple is the
+grantor of rights, (i) claims of patents that are now or hereafter acquired,
+owned by or assigned to Apple and (ii) that cover subject matter contained in
+the Original Code, but only to the extent necessary to use, reproduce and/or
+distribute the Original Code without infringement; and (b) in the case where
+You are the grantor of rights, (i) claims of patents that are now or hereafter
+acquired, owned by or assigned to You and (ii) that cover subject matter in
+Your Modifications, taken alone or in combination with Original Code.
+
+1.2	"Contributor" means any person or entity that creates or contributes to
+the creation of Modifications.
+
+1.3	 "Covered Code" means the Original Code, Modifications, the combination
+of Original Code and any Modifications, and/or any respective portions thereof.
+
+1.4	"Externally Deploy" means: (a) to sublicense, distribute or otherwise
+make Covered Code available, directly or indirectly, to anyone other than You;
+and/or (b) to use Covered Code, alone or as part of a Larger Work, in any way
+to provide a service, including but not limited to delivery of content, through
+electronic communication with a client other than You.
+
+1.5	"Larger Work" means a work which combines Covered Code or portions
+thereof with code not governed by the terms of this License.
+
+1.6	"Modifications" mean any addition to, deletion from, and/or change to,
+the substance and/or structure of the Original Code, any previous
+Modifications, the combination of Original Code and any previous Modifications,
+and/or any respective portions thereof.  When code is released as a series of
+files, a Modification is:  (a) any addition to or deletion from the contents of
+a file containing Covered Code; and/or (b) any new file or other representation
+of computer program statements that contains any part of Covered Code. 
+
+1.7	"Original Code" means (a) the Source Code of a program or other work as
+originally made available by Apple under this License, including the Source
+Code of any updates or upgrades to such programs or works made available by
+Apple under this License, and that has been expressly identified by Apple as
+such in the header file(s) of such work; and (b) the object code compiled from
+such Source Code and originally made available by Apple under this License
+
+1.8	"Source Code" means the human readable form of a program or other work
+that is suitable 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 (object code).
+
+1.9	"You" or "Your" means an individual or a legal entity exercising rights
+under this License.  For legal entities, "You" or "Your" includes any entity
+which controls, is controlled by, or is under common control with, You, where
+"control" means (a) the power, direct or indirect, to cause the direction or
+management of such entity, whether by contract or otherwise, or (b) ownership
+of fifty percent (50%) or more of the outstanding shares or beneficial
+ownership of such entity.
+
+2.	Permitted Uses; Conditions & Restrictions.   Subject to the terms and
+conditions of this License, Apple hereby grants You, effective on the date You
+accept this License and download the Original Code, a world-wide, royalty-free,
+non-exclusive license, to the extent of Apple's Applicable Patent Rights and
+copyrights covering the Original Code, to do the following:
+
+2.1	Unmodified Code.  You may use, reproduce, display, perform, internally
+distribute within Your organization, and Externally Deploy verbatim, unmodified
+copies of the Original Code, for commercial or non-commercial purposes,
+provided that in each instance:
+
+(a)	You must retain and reproduce in all copies of Original Code the
+copyright and other proprietary notices and disclaimers of Apple as they appear
+in the Original Code, and keep intact all notices in the Original Code that
+refer to this License; and
+
+(b) 	You must include a copy of this License with every copy of Source Code
+of Covered Code and documentation You distribute or Externally Deploy, and You
+may not offer or impose any terms on such Source Code that alter or restrict
+this License or the recipients' rights hereunder, except as permitted under
+Section 6.
+
+2.2	Modified Code.  You may modify Covered Code and use, reproduce,
+display, perform, internally distribute within Your organization, and
+Externally Deploy Your Modifications and Covered Code, for commercial or
+non-commercial purposes, provided that in each instance You also meet all of
+these conditions:
+
+(a)	You must satisfy all the conditions of Section 2.1 with respect to the
+Source Code of the Covered Code; 
+
+(b)	You must duplicate, to the extent it does not already exist, the notice
+in Exhibit A in each file of the Source Code of all Your Modifications, and
+cause the modified files to carry prominent notices stating that You changed
+the files and the date of any change; and
+
+(c)	If You Externally Deploy Your Modifications, You must make Source Code
+of all Your Externally Deployed Modifications either available to those to whom
+You have Externally Deployed Your Modifications, or publicly available.  Source
+Code of Your Externally Deployed Modifications must be released under the terms
+set forth in this License, including the license grants set forth in Section 3
+below, for as long as you Externally Deploy the Covered Code or twelve (12)
+months from the date of initial External Deployment, whichever is longer. You
+should preferably distribute the Source Code of Your Externally Deployed
+Modifications electronically (e.g. download from a web site).
+
+2.3	Distribution of Executable Versions.  In addition, if You Externally
+Deploy Covered Code (Original Code and/or Modifications) in object code,
+executable form only, You must include a prominent notice, in the code itself
+as well as in related documentation, stating that Source Code of the Covered
+Code is available under the terms of this License with information on how and
+where to obtain such Source Code.  
+
+2.4	Third Party Rights.  You expressly acknowledge and agree that although
+Apple and each Contributor grants the licenses to their respective portions of
+the Covered Code set forth herein, no assurances are provided by Apple or any
+Contributor that the Covered Code does not infringe the patent or other
+intellectual property rights of any other entity. Apple and each Contributor
+disclaim any liability to You for claims brought by any other entity based on
+infringement of intellectual property rights or otherwise. As a condition to
+exercising the rights and licenses granted hereunder, You hereby assume sole
+responsibility to secure any other intellectual property rights needed, if any.
+For example, if a third party patent license is required to allow You to
+distribute the Covered Code, it is Your responsibility to acquire that license
+before distributing the Covered Code.
+
+3.	Your Grants.  In consideration of, and as a condition to, the licenses
+granted to You under this License, You hereby grant to any person or entity
+receiving or distributing Covered Code under this License a non-exclusive,
+royalty-free, perpetual, irrevocable license, under Your Applicable Patent
+Rights and other intellectual property rights (other than patent) owned or
+controlled by You, to use, reproduce, display, perform, modify, sublicense,
+distribute and Externally Deploy Your Modifications of the same scope and
+extent as Apple's licenses under Sections 2.1 and 2.2 above.  
+
+4.	Larger Works.  You may create a Larger Work by combining Covered Code
+with other code not governed by the terms of this License and distribute the
+Larger Work as a single product.  In each such instance, You must make sure the
+requirements of this License are fulfilled for the Covered Code or any portion
+thereof. 
+
+5.	Limitations on Patent License.   Except as expressly stated in Section
+2, no other patent rights, express or implied, are granted by Apple herein.
+Modifications and/or Larger Works may require additional patent licenses from
+Apple which Apple may grant in its sole discretion.  
+
+6.	Additional Terms.  You may choose to offer, and to charge a fee for,
+warranty, support, indemnity or liability obligations and/or other rights
+consistent with the scope of the license granted herein ("Additional Terms") to
+one or more recipients of Covered Code. However, You may do so only on Your own
+behalf and as Your sole responsibility, and not on behalf of Apple or any
+Contributor. You must obtain the recipient's agreement that any such Additional
+Terms are offered by You alone, and You hereby agree to indemnify, defend and
+hold Apple and every Contributor harmless for any liability incurred by or
+claims asserted against Apple or such Contributor by reason of any such
+Additional Terms. 
+
+7.	Versions of the License.  Apple may publish revised and/or new versions
+of this License from time to time.  Each version will be given a distinguishing
+version number.  Once Original Code has been published under a particular
+version of this License, You may continue to use it under the terms of that
+version. You may also choose to use such Original Code under the terms of any
+subsequent version of this License published by Apple.  No one other than Apple
+has the right to modify the terms applicable to Covered Code created under this
+License.  
+
+8.	NO WARRANTY OR SUPPORT.  The Covered Code may contain in whole or in
+part pre-release, untested, or not fully tested works.  The Covered Code may
+contain errors that could cause failures or loss of data, and may be incomplete
+or contain inaccuracies.  You expressly acknowledge and agree that use of the
+Covered Code, or any portion thereof, is at Your sole and entire risk.  THE
+COVERED CODE IS PROVIDED "AS IS" AND WITHOUT WARRANTY, UPGRADES OR SUPPORT OF
+ANY KIND AND APPLE AND APPLE'S LICENSOR(S) (COLLECTIVELY REFERRED TO AS "APPLE"
+FOR THE PURPOSES OF SECTIONS 8 AND 9) AND ALL CONTRIBUTORS EXPRESSLY DISCLAIM
+ALL WARRANTIES AND/OR CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT NOT
+LIMITED TO, THE IMPLIED WARRANTIES AND/OR CONDITIONS OF MERCHANTABILITY, OF
+SATISFACTORY QUALITY, OF FITNESS FOR A PARTICULAR PURPOSE, OF ACCURACY, OF
+QUIET ENJOYMENT, AND NONINFRINGEMENT OF THIRD PARTY RIGHTS.  APPLE AND EACH
+CONTRIBUTOR DOES NOT WARRANT AGAINST INTERFERENCE WITH YOUR ENJOYMENT OF THE
+COVERED CODE, THAT THE FUNCTIONS CONTAINED IN THE COVERED CODE WILL MEET YOUR
+REQUIREMENTS, THAT THE OPERATION OF THE COVERED CODE WILL BE UNINTERRUPTED OR
+ERROR-FREE, OR THAT DEFECTS IN THE COVERED CODE WILL BE CORRECTED.  NO ORAL OR
+WRITTEN INFORMATION OR ADVICE GIVEN BY APPLE, AN APPLE AUTHORIZED
+REPRESENTATIVE OR ANY CONTRIBUTOR SHALL CREATE A WARRANTY.  You acknowledge
+that the Covered Code is not intended for use in the operation of nuclear
+facilities, aircraft navigation, communication systems, or air traffic control
+machines in which case the failure of the Covered Code could lead to death,
+personal injury, or severe physical or environmental damage.
+
+9.	LIMITATION OF LIABILITY. TO THE EXTENT NOT PROHIBITED BY LAW, IN NO
+EVENT SHALL APPLE OR ANY CONTRIBUTOR BE LIABLE FOR ANY INCIDENTAL, SPECIAL,
+INDIRECT OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATING TO THIS LICENSE OR
+YOUR USE OR INABILITY TO USE THE COVERED CODE, OR ANY PORTION THEREOF, WHETHER
+UNDER A THEORY OF CONTRACT, WARRANTY, TORT (INCLUDING NEGLIGENCE), PRODUCTS
+LIABILITY OR OTHERWISE, EVEN IF APPLE OR SUCH CONTRIBUTOR HAS BEEN ADVISED OF
+THE POSSIBILITY OF SUCH DAMAGES AND NOTWITHSTANDING THE FAILURE OF ESSENTIAL
+PURPOSE OF ANY REMEDY. SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OF
+LIABILITY OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS LIMITATION MAY NOT
+APPLY TO YOU. In no event shall Apple's total liability to You for all damages
+(other than as may be required by applicable law) under this License exceed the
+amount of fifty dollars ($50.00).
+
+10.	Trademarks.  This License does not grant any rights to use the
+trademarks or trade names  "Apple", "Mac", "Mac OS", "QuickTime", "QuickTime
+Streaming Server" or any other trademarks, service marks, logos or trade names
+belonging to Apple (collectively "Apple Marks") or to any trademark, service
+mark, logo or trade name belonging to any Contributor.  You agree not to use
+any Apple Marks in or as part of the name of products derived from the Original
+Code or to endorse or promote products derived from the Original Code other
+than as expressly permitted by and in strict compliance at all times with
+Apple's third party trademark usage guidelines which are posted at
+http://www.apple.com/legal/guidelinesfor3rdparties.html.  
+
+11.	Ownership. Subject to the licenses granted under this License, each
+Contributor retains all rights, title and interest in and to any Modifications
+made by such Contributor.  Apple retains all rights, title and interest in and
+to the Original Code and any Modifications made by or on behalf of Apple
+("Apple Modifications"), and such Apple Modifications will not be automatically
+subject to this License.  Apple may, at its sole discretion, choose to license
+such Apple Modifications under this License, or on different terms from those
+contained in this License or may choose not to license them at all.  
+
+12.	Termination.  
+
+12.1	Termination.  This License and the rights granted hereunder will
+terminate:
+
+(a)	automatically without notice from Apple if You fail to comply with any
+term(s) of this License and fail to cure such breach within 30 days of becoming
+aware of such breach; (b)	immediately in the event of the circumstances
+described in Section 13.5(b); or (c)	automatically without notice from Apple
+if You, at any time during the term of this License, commence an action for
+patent infringement against Apple; provided that Apple did not first commence
+an action for patent infringement against You in that instance.
+
+12.2	Effect of Termination.  Upon termination, You agree to immediately stop
+any further use, reproduction, modification, sublicensing and distribution of
+the Covered Code.  All sublicenses to the Covered Code which have been properly
+granted prior to termination shall survive any termination of this License.
+Provisions which, by their nature, should remain in effect beyond the
+termination of this License shall survive, including but not limited to
+Sections 3, 5, 8, 9, 10, 11, 12.2 and 13.  No party will be liable to any other
+for compensation, indemnity or damages of any sort solely as a result of
+terminating this License in accordance with its terms, and termination of this
+License will be without prejudice to any other right or remedy of any party.
+
+13. 	Miscellaneous.
+
+13.1	Government End Users.   The Covered Code is a "commercial item" as
+defined in FAR 2.101.  Government software and technical data rights in the
+Covered Code include only those rights customarily provided to the public as
+defined in this License. This customary commercial license in technical data
+and software is provided in accordance with FAR 12.211 (Technical Data) and
+12.212 (Computer Software) and, for Department of Defense purchases, DFAR
+252.227-7015 (Technical Data -- Commercial Items) and 227.7202-3 (Rights in
+Commercial Computer Software or Computer Software Documentation).  Accordingly,
+all U.S. Government End Users acquire Covered Code with only those rights set
+forth herein.
+
+13.2	Relationship of Parties.  This License will not be construed as
+creating an agency, partnership, joint venture or any other form of legal
+association between or among You, Apple or any Contributor, and You will not
+represent to the contrary, whether expressly, by implication, appearance or
+otherwise.
+
+13.3	Independent Development.   Nothing in this License will impair Apple's
+right to acquire, license, develop, have others develop for it, market and/or
+distribute technology or products that perform the same or similar functions
+as, or otherwise compete with, Modifications, Larger Works, technology or
+products that You may develop, produce, market or distribute.
+
+13.4	Waiver; Construction.  Failure by Apple or any Contributor to enforce
+any provision of this License will not be deemed a waiver of future enforcement
+of that or any other provision.  Any law or regulation which provides that the
+language of a contract shall be construed against the drafter will not apply to
+this License.
+
+13.5	Severability.  (a) If for any reason a court of competent jurisdiction
+finds any provision of this License, or portion thereof, to be unenforceable,
+that provision of the License will be enforced to the maximum extent
+permissible so as to effect the economic benefits and intent of the parties,
+and the remainder of this License will continue in full force and effect.  (b)
+Notwithstanding the foregoing, if applicable law prohibits or restricts You
+from fully and/or specifically complying with Sections 2 and/or 3 or prevents
+the enforceability of either of those Sections, this License will immediately
+terminate and You must immediately discontinue any use of the Covered Code and
+destroy all copies of it that are in your possession or control.
+
+13.6	Dispute Resolution.  Any litigation or other dispute resolution between
+You and Apple relating to this License shall take place in the Northern
+District of California, and You and Apple hereby consent to the personal
+jurisdiction of, and venue in, the state and federal courts within that
+District with respect to this License. The application of the United Nations
+Convention on Contracts for the International Sale of Goods is expressly
+excluded.
+
+13.7	Entire Agreement; Governing Law.  This License constitutes the entire
+agreement between the parties with respect to the subject matter hereof.  This
+License shall be governed by the laws of the United States and the State of
+California, except that body of California law concerning conflicts of law. 
+
+Where You are located in the province of Quebec, Canada, the following clause
+applies:  The parties hereby confirm that they have requested that this License
+and all related documents be drafted in English.  Les parties ont exigé que le
+présent contrat et tous les documents connexes soient rédigés en anglais.
