You may choose to offer, and to charge a + fee for, warranty, support, indemnity or liability + obligations to one or more recipients of Covered Software. + However, you may do so only on Your own behalf, and not on + behalf of the Initial Developer or any Contributor. You + must make it absolutely clear that any such warranty, + support, indemnity or liability obligation is offered by + You alone, and You hereby agree to indemnify the Initial + Developer and every Contributor for any liability incurred + by the Initial Developer or such Contributor as a result of + warranty, support, indemnity or liability terms You offer. + + + 3.5.

If the Initial Developer includes a + notice in the Original Software prohibiting it from being + distributed or otherwise made available under any + subsequent version of the License, You must distribute and + make the Covered Software available under the terms of the + version of the License under which You originally received + the Covered Software. Otherwise, You may also choose to + use, distribute or otherwise make the Covered Software + available under the terms of any subsequent version of the + License published by the license steward. + + 4.3. Modified Versions. + + When You are an Initial Developer and You want to create a + new license for Your Original Software, You may create and + use a modified version of this License if You: (a) rename + the license and remove any references to the name of the + license steward (except to note that the license differs + from this License); and (b) otherwise make it clear that + the license contains terms which differ from this License. + + + 5.

THIS DISCLAIMER OF + WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF + ANY COVERED SOFTWARE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS + DISCLAIMER. + + 6. TERMINATION. + + 6.1. This License and the rights granted hereunder will + terminate automatically if You fail to comply with terms + herein and fail to cure such breach within 30 days of + becoming aware of the breach. Provisions which, by their + nature, must remain in effect beyond the termination of + this License shall survive. + + 6.2. If You assert a patent infringement claim (excluding + declaratory judgment actions) against Initial Developer or + a Contributor (the Initial Developer or Contributor against + whom You assert such claim is referred to as 'Participant') + alleging that the Participant Software (meaning the + Contributor Version where the Participant is a Contributor + or the Original Software where the Participant is the + Initial Developer) directly or indirectly infringes any + patent, then any and all rights granted directly or + indirectly to You by such Participant, the Initial + Developer (if the Initial Developer is not the Participant) + and all Contributors under Sections 2.1 and/or 2.2 of this + License shall, upon 60 days notice from Participant + terminate prospectively and automatically at the expiration + of such 60 day notice period, unless if within such 60 day + period You withdraw Your claim with respect to the + Participant Software against such Participant either + unilaterally or pursuant to a written agreement with + Participant. + + 6.3. In the event of termination under Sections 6.1 or 6.2 + above, all end user licenses that have been validly granted + by You or any distributor hereunder prior to termination + (excluding licenses granted to You by any distributor) + shall survive termination. + + 7. LIMITATION OF LIABILITY. + + UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT + (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE + INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF + COVERED SOFTWARE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE + LIABLE TO ANY PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR + CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT + LIMITATION, DAMAGES FOR LOST PROFITS, LOSS OF GOODWILL, WORK + STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER + COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN + INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF + LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL + INJURY RESULTING FROM SUCH PARTYÕS NEGLIGENCE TO THE EXTENT + APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO + NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR + CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION AND LIMITATION MAY NOT + APPLY TO YOU. + + 8. U.S. GOVERNMENT END USERS. + + The Covered Software is a 'commercial item,' as that term is + defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of 'commercial + computer software' (as that term is defined at 48 C.F.R. ¤ + 252.227-7014(a)(1)) and 'commercial computer software + documentation' as such terms are used in 48 C.F.R. 12.212 (Sept. + 1995). Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 + through 227.7202-4 (June 1995), all U.S. Government End Users + acquire Covered Software with only those rights set forth herein. + This U.S. Government Rights clause is in lieu of, and supersedes, + any other FAR, DFAR, or other clause or provision that addresses + Government rights in computer software under this License. + + 9. MISCELLANEOUS. + + This License represents the complete agreement concerning subject + matter hereof. If any provision of this License is held to be + unenforceable, such provision shall be reformed only to the + extent necessary to make it enforceable. This License shall be + governed by the law of the jurisdiction specified in a notice + contained within the Original Software (except to the extent + applicable law, if any, provides otherwise), excluding such + jurisdictionÕs conflict-of-law provisions. Any litigation + relating to this License shall be subject to the jurisdiction of + the courts located in the jurisdiction and venue specified in a + notice contained within the Original Software, with the losing + party responsible for costs, including, without limitation, court + costs and reasonable attorneysÕ fees and expenses. The + application of the United Nations Convention on Contracts for the + International Sale of Goods is expressly excluded. Any law or + regulation which provides that the language of a contract shall + be construed against the drafter shall not apply to this License. + You agree that You alone are responsible for compliance with the + United States export administration regulations (and the export + control laws and regulation of any other countries) when You use, + distribute or otherwise make available any Covered Software. + + 10. RESPONSIBILITY FOR CLAIMS. + + As between Initial Developer and the Contributors, each party is + responsible for claims and damages arising, directly or + indirectly, out of its utilization of rights under this License + and You agree to work with Initial Developer and Contributors to + distribute such responsibility on an equitable basis. Nothing + herein is intended or shall be deemed to constitute any admission + of liability. diff --git a/LICENSE_LGPL.txt b/LICENSE_LGPL.txt new file mode 100644 index 0000000..8365aea --- /dev/null +++ b/LICENSE_LGPL.txt @@ -0,0 +1,20 @@ +RIFE, + +Copyright 2001-2006 Geert Bevin , + +Distributed under the GNU Lesser General Public License v2.1. + +This library is free software; you can redistribute it and/or +modify it under the terms of the GNU Lesser General Public +License as published by the Free Software Foundation; either +version 2.1 of the License, or (at your option) any later version. + +This library is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
