-osmo-mgw - Osmocom MGW (Media GateWay) Implementation
-=====================================================
-
-This repository contains a C-language implementation of an MGW (Media
-GateWay) for use [not only] within the 2G (GSM) and/or 3G (UMTS)
-Cellular Network built using Osmocom CNI (Cellular Network
-Infrastructure) software.
-
-The OsmoMGW program provides an MGCP interface towards an MGCP call agent
-(client) like OsmoMSC and OsmoBSC, and receives and sends RTP streams as
-configured via the MGCP control plane.
-
-This Media Gateway implementation is capable of
-
-* streaming RTP for 2G (3GPP AoIP and Abis-over-IP)
-* streaming RTP for 3G (IuCS including the IuFP protocol)
-* TDM (E1/T1) based Abis interface with TRAU frames on 16k sub-slots
-* basic support for LCLS (Local Call, Local Switch) related features
-* various built-in translation capabilities
-  * between Abis TRAU frames and RTP formats
-  * between 2G AMR/RTP and 3G AMR/IuFP/RTP
-  * between bandwidth-efficient and octet-aligned AMR
-  * between different standards for encapsulating GSM HR codec frames in RTP
-
-osmo-mgw is typically co-located with
-
- * osmo-bsc (GSM BSC)
- * osmo-msc (GSM/UMTS MSC)
- * osmo-hnbgw (UMTS HNBGW); osmo-mgw implements RTP relay between Iuh
-   and IuCS interfaces
-
-The libosmo-mgcp-client library exposes utilities used by e.g. OsmoMSC
-(found in osmo-msc.git) to instruct OsmoMGW via its MGCP service.

-History
--------
-
-OsmoMGW originated from the OpenBSC project, which started as a minimalistic
-all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached
-maturity and diversity (including M3UA SIGTRAN and 3G support in the form of
-IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one
-approach to fully independent separate programs as in typical GSM networks.
-
-OsmoMGW was one of the parts split off from the old openbsc.git. It originated
-as a solution to merely navigate RTP streams through a NAT, but has since
-matured.

-== Configuring OsmoMGW
-
-A basic configation of OsmoMGW mainly consists of specifying the IP address
-and port on which to listen to MGCP commands, but changing the port range at
-which the RTP streams terminate as well as limiting operation to a single call
-agent can be done as well as changing the number of endpoints.
-
-=== Configuring MGCP
-
-By default OsmoMGW listens for MGCP on port 2427 on any IP address. If a call
-agent address is configured then OsmoMGW will only answer MGCP commands from
-that IP port 2727, otherwise all sources are handled. A domain can be
-specified
-
-.Example: MGCP configuration
-----
-OsmoMGW(config-mgcp)# bind ip 127.0.0.1
-OsmoMGW(config-mgcp)# bind port 2427
-OsmoMGW(config-mgcp)# call-agent ip 127.0.0.1
-OsmoMGW(config-mgcp)# domain mgw-bsc
-OsmoMGW(config-mgcp)# local ip 127.0.0.1
-----
-
-=== Configuring the trunk
-
-The first trunk is considered a virtual trunk in OsmoMGW. All
-endpoints of type "rtpbridge" are routed here. The virtual trunk is configured
-in the config-mgcp context.
-
-All other trunks are configured in the config-mgcp-trunk context, but the
-commands used are identical. Right now trunks are considered only for "ds/e1"
-type endpoints.
-
-.Example: MGCP trunk configuration
-----
-OsmoMGW(config-mgcp)# number endpoints 63 <1>
-OsmoMGW(config-mgcp)# rtp bind-ip 10.0.0.1 <2>
-OsmoMGW(config-mgcp)# rtp port-range 12000-14000 <3>
-----
-<1> Maximum number of endpoints that can be allocated at once
-<2> Use this IP when binding RTP endpoints
-<3> Use ports in this range when binding RTP endpoints
-
-There are some options to tweak how RTP forwarding behaves in OsmoMGW:
-
-.Example: MGCP trunk rtp options
-----
-OsmoMGW(config-mgcp)# rtp keep-alive 30 <1>
-OsmoMGW(config-mgcp)# rtp-patch ssrc <2>
-OsmoMGW(config-mgcp)# rtp-patch timestamp <3>
-----
-<1> Send dummy UDP packets periodically to RTP destination
-<2> Hide SSRC changes
-<3> Ensure RTP timestamp is aligned with frame duration
-
-NOTE: Changes to trunks that affect resource allocation, such as newly created
-trunks or a change of the number of available endpoints, require a full restart
-of osmo-mgw!
-
-=== E1 trunk considerations
-
-While the RTP bridge trunks are natively based on IP no special considerations
-are required during setup. E1 trunks are mapped on a physical E1 line, which has
-to be configured as shown below.
-
-.Example: E1 line setup
-----
-OsmoMGW(config-e1_input)# e1_line 0 driver dahdi <1>
-OsmoMGW(config-e1_input)# e1_line 0 port 2 <2>
-----
-<1> Name of the libosmo-abis driver implementation ("dahdi")
-<2> Port number of the physical E1 port to use (2)
-
-In osmo-mgw the e1_input node is used to configure the physical E1 line. The
-line number will be used internally to identify the configured E1 line. The
-port number is the physical E1 connector (sometimes called 'span') at the E1
-hardware. Per trunk an individual E1 line will be needed. Beware that the E1
-driver may also need configuration settings that are not discussed here.
-
-.Example: E1 trunk setup
-----
-OsmoMGW(config-mgcp)# trunk 0 <1>
-OsmoMGW(config-mgcp-trunk)# line 0 <2>
-----
-<1> Creation of a trunk (0)
-<2> Reference to the E1 line to use (0)
-
-The E1 trunk is created along with a number, typically starting at 0, but if
-required any number from 0-64 is allowed. The E1 trunk configuration concerning
-the IP related aspects is nearly identical to the configuration of the virtual
-trunk. However, it is important that the user assigns one of the E1 line numbers
-that were configured under the e1_input node.
-
-NOTE: The endpoint name that is used on MGCP level will include the trunk number,
-not the E1 line number. For simplicity (and compatibility with OsmoBSC) it is
-recommended to use equal numbers for trunk and E1 line. However, if required any
-E1 line can be mapped flexible on any trunk as long as the mapping is bijective.
-
-.Example: A typical configuration with one E1 trunk
-----
-e1_input
- e1_line 0 driver dahdi
- e1_line 0 port 2
-mgcp
- bind ip 127.0.0.1
- rtp net-range 6000 6011
- rtp net-bind-ip 192.168.100.130
- rtp ip-probing
- rtp ip-dscp 46
- no rtp keep-alive
- bind port 2428
- number endpoints 30
- loop 0
- force-realloc 1
- osmux off
- rtp-patch rfc5993hr
- trunk 0
-  rtp keep-alive once
-  no rtp keep-alive
-  line 0
-----
-
-NOTE: One E1 trunk always covers a whole E1 line. All subslots (I.640) will be mapped
-to individual MGCP endpoints. As long as the endpoints remain unused the
-underlying E1 timeslot is not used.
-
-NOTE: The E1 trunk implementation also works with T1 lines, however since T1 has
-24 instead of 31 usable timeslots only the endpoints that fall into that 1-24 timeslot
-range will be useable.

-== MGCP Endpoints
-
-MGCP organizes the switching resources in so called endpoints. Each endpoint is
-referenced by its unique identifier. While RFC 3435 specifies a naming scheme, the
-actual identifier naming is subject to the implementation and configuration.
-
-=== RTP proxy / RTP bridge endpoints
-
-OsmoMGW implements a freely configurable number of `rtpbridge` endpoints. Those
-endpoints are able to host two connections at a time to model the functionality
-of a tandem switch.
-
-RTP bridge endpoint identifiers are referenced by the string `rtpbridge/`, a
-hexadecimal number without leading zeros and a domain name (configurable).

-=== E1/T1 endpoints
-
-OsmoMGW supports E1 subslot multiplexing as specified by I.460. All possible
-subslot combinations are mapped on individual endpoints. The endpoint names
-are prefixed with `ds/e1-` followed by the trunk number and the E1 timeslot.
-The subslot is defined by a bit rate and a bit offset.

@@ -1,154 +0,0 @@
-== MGCP Extensions
-
-The MGCP protocol is extendable. The following non-standard extensions are
-understood by OsmoMGW.
-
-=== `X-Osmo-IGN`
-
-`X-Osmo-IGN` indicates to OsmoMGW that specific items of an endpoint should be
-ignored, so that it is lenient on mismatching values that would normally
-indicate collisions or configuration errors.
-
-==== `X-Osmo-IGN` Format
-
-The value part of `X-Osmo-IGN` must be one or more items separated by one or more
-spaces. Each item consists of one or more non-whitespace characters.
-
-.Example: `X-Osmo-IGN` format with three ficticious items "X", "abc" and "123".
-----
-X-Osmo-IGN: X abc 123
-----
-
-`X-Osmo-IGN` must be issued in the MGCP header section (typically as its last item),
-before the SDP section starts.
-
-==== Supported `X-Osmo-IGN` Items
-
-Currently, the following `X-Osmo-IGN` items are supported:
-
-* `C`: ignore CallID mismatches, i.e. differing "C" values between connections
-  on the same endpoint.
-
-.Note:
-`X-Osmo-IGN` does not support ignoring mismatches on the domain part of
-an endpoint name, e.g. ignoring a mismatch on "example.com" in
-`rtpbridge/123abc@example.com`. Instead, you may globally configure OsmoMGW
-with `mgcp` / `domain *` to permit all domain parts.
-
-===== `X-Osmo-IGN: C`
-
-By default, OsmoMGW verifies that all CallIDs ("C" values) match for all
-connections on any one given endpoint. To ignore CallID mismatches, pass a `C`
-in the `X-Osmo-IGN` header, for the first or the second `CRCX` on an endpoint.
-When the `X-Osmo-IGN: C` is sent for any one `CRCX` on an endpoint, CallID
-mismatches will be ignored for that and all subsequent messages for that
-endpoint. Hence this header only needs to be included once per endpoint, in any
-`CRCX` message that precedes or coincides with a CallID mismatch.
-
-This is particularly useful for a BSC that is connected to an A/SCCPlite MSC,
-where the BSC and MSC each are expected to configure their respective own
-connection on a shared endpoint. For A/SCCPlite, it is impossible for the BSC
-to know the CallID that the MSC will use, so CallID mismatches are inevitable.
-See also OsmoBSC, which will by default pass the `X-Osmo-IGN: C` header for
-endpoints associated with an A/SCCPlite MSC.
-
-.Example: `CRCX` message that instructs OsmoMGW to ignore CallID mismatches

-----
-
-=== `X-Osmux`
-
-See <<mgcp-extension-osmux>>
-
-=== Non-standard SDP codec parameters
-
-CRCX command message normally includes an SDP block that specifies the RTP
-address of the connecting peer and the list of codecs accepted by that entity.
-Codec specifications may include optional parameters given via `a=fmtp` lines;
-one well-known parameter is `octet-align`, defined for AMR and AMR-WB codecs.
-
-In addition to standard (RFC-defined) codec parameters (of which the
-just-mentioned `octet-align` parameter is the only one implemented so far),
-OsmoMGW also understands some non-standard (Osmocom-private) codec parameters
-as listed below.
-These Osmocom-private codec parameters are meaningful only in the context
-of OsmoBSC driving an E1 Abis MGW, which may be either OsmoMGW or a specialized
-third-party replacement.
-
-The MGCP extension described in this section is meaningful only for E1
-endpoints - it has absolutely no effect on `rtpbridge` endpoints!
-
-==== `tw-ts-001` parameter for FR and EFR codecs
-
-GSM Full Rate codec is known in SDP as `GSM`; GSM Enhanced Full Rate codec
-is known in SDP as `GSM-EFR`.
-When either codec is to be transported in RTP, there is a choice between
-two different payload formats: RFC 3551 or TW-TS-001.
-RFC 3551 is the standard in non-GSM Internet applications, and it is the
-format specified in later 3GPP releases for IP-based transport of
-compressed speech - however, it exhibits functional regressions compared
-to the original TRAU-UL frame format of GSM 08.60.
-TW-TS-001 is an enhanced alternative payload format for the same codecs
-that restores the original functionality and semantics of TRAU-UL frames.
-
-In the context of CRCX or MDCX command messages from OsmoBSC to an E1 Abis MGW,
-`tw-ts-001` codec parameter (attached to either `GSM` or `GSM-EFR` codec)
-instructs the MGW whether or not it should emit the extended payload format
-of TW-TS-001 for GSM uplink traffic converted to RTP.
-In the absence of this parameter, IETF-standard and 3GPP-standard RFC 3551
-format is emitted; if TW-TS-001 output is desired, please specify
-`tw-ts-001=1` on the appropriate `a=fmtp` line.
-
-.Example: `CRCX` message requesting EFR codec with TW-TS-001 extensions

-==== `tw-ts-002` parameter for HR codec
-
-GSM Half Rate codec is known in SDP as `GSM-HR-08`.
-The same dichotomy that exists between RFC 3551 and TW-TS-001 RTP payload
-formats for FR and EFR codecs also exists for HR codec, except that
-the two opposing alternatives are now RFC 5993 and TW-TS-002.
-
-In the context of CRCX or MDCX command messages from OsmoBSC to an E1 Abis MGW,
-`tw-ts-002` codec parameter (attached to `GSM-HR-08` codec)
-instructs the MGW whether or not it should emit the extended payload format
-of TW-TS-002 for GSM uplink traffic converted to RTP.
-In the absence of this parameter, IETF-standard and 3GPP-standard RFC 5993
-format is emitted; if TW-TS-002 output is desired, please specify
-`tw-ts-002=1` on the appropriate `a=fmtp` line.

-== Overview
-
-This manual should help you getting started with OsmoMGW. It will cover
-aspects of configuring and running the media gateway.
-
-[[intro_overview]]
-=== About OsmoMGW
-
-OsmoMGW is the Osmocom implementation of a media gateway to handle user
-plane (voice) traffic in cellular networks. It can connect and optionally
-transcode RTP voice streams between different network elements such as BTSs
-and external entities like SIP. It is typically co-located with both OsmoBSC
-and OsmoMSC and controlled by them via MGCP, the Media Gateway Control
-Protocol.

-=== Software Components
-
-OsmoMGW contains a variety of different software components, which we’ll
-quickly describe in this section.
-
-==== MGCP Implementation
-
-OsmoMGW brings its own MGCP implementation through which OsmoMGW is
-controlled.
-
-The commands implemented are CRCX, MDCX, DLCX and RSIP. The command AUEP is
-implemented as a stub and will simply respond with OK.
-
-==== RTP implementation
-
-Support for IuUP which is used in 3G cells is quite lacking at the moment.
-3G<->3G and 2G<->2G calls should work, but 3G<->2G does not.
-
-==== Audio transcoder
-
-Transcoding is currently not supported in OsmoMGW.
-
-=== Limitations
-
-At the moment (November 2020), OsmoMGW implements RTP proxy / RTP bridge
-type endpoints and E1/T1 16k/8k sub-slots with TRAU frames for classic BTS
-support. To the RTP proxy / RTP bridge endpoints two RTP connections can
-be established, which then work as a tandem. E1/T1 endpoints support one
-RTP connection at a time that is associated with a sub-slot on an E1 line.
-We are planning to add further endpoint types for:
-
-- classic E1/T1 timeslots (64kBps alaw/ulaw)
-- announcement/playout end-points
-- conference endpoints
-
-=== Additional resources
-
-You can find the OsmoMGW issue tracker and wiki online at
-

-- https://osmocom.org/projects/osmo-mgw/wiki

-==== Full example of QoS for osmo-mgw
-
-In the below example we will show the full set of configuration required
-for both DSCP and PCP differentiation of RTP traffic by osmo-mgw.
-
-What we want to achieve in this example is the following configuration:
-
-.DSCP and PCP assignments for osmo-mgw Abis downlink traffic in this example
-[options="header",width="30%",cols="2,1,1"]
-|===
-|Traffic      |DSCP|PCP
-|RTP    |  46|  6
-|===
-
-. configure the osmo-mgw program to set the DSCP value
-. configure an egrees QoS map to map from priority to PCP
-
-.Example Step 1: add related VTY configuration to `osmo-mgw.cfg`
-----
-...
-mgcp
- rtp ip-dscp 46
- rtp socket-priority 6
-...
-----
-
-.Example Step 2: egress QoS map to map from socket priority to PCP values
-----
-$ sudo ip link set dev eth0.9<1> type vlan egress-qos-map 0:0 5:5 6:6 7:7 <2>
-----
-<1> make sure to specify your specific VLAN interface name here instead of `eth0.9`.
-<2> create a egress QoS map that maps the priority value 1:1 to the PCP. We also include the
-    mapping 5:5 and 7:7 from the osmo-bsc example (see <<userman-osmobsc>>) here.
-
-NOTE:: The settings of the `ip` command are volatile and only active until
-the next reboot (or the network device or VLAN is removed).  Please refer to
-the documentation of your specific Linux distribution in order to find out how
-to make such settings persistent by means of an `ifup` hook whenever the interface
-comes up.  For CentOS/RHEL 8 this can e.g. be achieved by means of an `/sbin/ifup-local
-script` (when using `network-scripts` and not NetworkManager).  For Debian or Ubuntu,
-this typically involves adding `up` lines to `/etc/network/interfaces` or a `/etc/network/if-up.d`
-script.

-== Running OsmoMGW
-
-The OsmoMGW executable (`osmo-mgw`) offers the following command-line
-arguments:
-
-=== SYNOPSIS
-
-*osmo-mgw* [-h|-V] [-D] [-c 'CONFIGFILE'] [-s]
-
-=== OPTIONS
-
-*-h, --help*::
-	Print a short help message about the supported options
-*-V, --version*::
-	Print the compile-time version number of the program
-*-D, --daemonize*::
-	Fork the process as a daemon into background.
-*-c, --config-file 'CONFIGFILE'*::
-	Specify the file and path name of the configuration file to be
-	used. If none is specified, use `osmo-mgw.cfg` in the current
-	working directory.
-*-s, --disable-color*::
-	Disable colors for logging to stderr. This has mostly been
-	deprecated by VTY based logging configuration, see <<logging>>
-	for more information.
-
-
-=== Configure limits
-
-When servicing hundreds of media endpoints, it may be necessary to adjust the
-operating system's limit on open file descriptors for the osmo-mgw process. A
-typical default limit imposed by operating systems is 1024; this would be
-exceeded by, for example, about 256 active voice calls with 4 RTP/RTPC ports
-each, sockets for other interfaces not considered yet.
-
-It should be ok to set an OS limit on open file descriptors as high as 65536
-for osmo-mgw, which practically rules out failure from running out of file
-descriptors anywhere (<16,000 active calls).
-
-When using systemd, the file descriptor limit may be adjusted in the service
-file by the `LimitNOFILE` setting ("Number of Open FILE descriptors"). OsmoMGW
-ships a systemd service file with a high LimitNOFILE setting.

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program 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.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.
