+
+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. (Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.)
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You only need
+`configure.ac' if you want to change it or regenerate `configure' using
+a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not support the `VPATH'
+variable, you have to compile the package for one architecture at a
+time in the source code directory. After you have installed the
+package for one architecture, use `make distclean' before reconfiguring
+for another architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the `--target=TYPE' option to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+will cause the specified gcc to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+Libjingle
+
+Libjingle is a set of components provided by Google to interoperate with Google
+Talk's peer-to-peer and voice capabilities. This package will create several
+static libraries you may link to your project as needed.
+
+-talk - No source files in talk/, just these subdirectories
+|-base - Contains basic low-level portable utility functions for
+| things like threads and sockets
+|-p2p - The P2P stack
+ |-base - Base p2p functionality
+ |-client - Hooks to tie it into XMPP
+|-session - Signaling
+ |-phone - Signaling code specific to making phone calls
+|-third_party - Components that aren't ours
+ |-mediastreamer - Media components for dealing with sound hardware and
+ | voice codecs
+|-xmllite - XML parser
+|-xmpp - XMPP engine
+
+In addition, this package contains two examples in talk/examples which
+illustrate the basic concepts of how the provided classes work.
+
+The xmllite component of libjingle depends on expat. You can download expat
+from http://expat.sourceforge.net/.
+
+mediastreamer, the media components used by the example applications depend on
+the oRTP and iLBC components from linphone, which can be found at
+http://www.linphone.org. Linphone, in turn depends on GLib, which can be found
+at http://www.gtk.org. This GLib dependency should be removed in future
+releases.
+
+Building Libjingle
+
+Once the dependencies are installed, run ./configure. ./configure will return
+an error if it failed to locate the proper dependencies. If ./configure
+succeeds, run 'make' to build the components and examples.
+
+When the build is complete, you can run the call example from
+talk/examples/call and the pcp example from talk/examples/pcp.
+
+Relay Server
+
+Libjingle will also build a relay server that may be used to relay traffic
+when a direct peer-to-peer connection could not be established. The relay
+server will build in talk/p2p/base/relayserver and will listen on UDP
+ports 5000 and 5001. See the Libjingle Developer Guide at
+http://code.google.com/apis/talk/index.html for information about configuring
+a client to use this relay server.
+
+STUN Server
+
+Lastly, Libjingle builds a STUN server which implements the STUN protocol for
+Simple Traversal of UDP over NAT. The STUN server is built as
+talk/p2p/base/stunserver and listens on UDP port 7000. See the Libjingle
+Developer Guide at http://code.google.com/apis/talk/index.html for information
+about configuring a client to use this STUN server.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a

+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']

+ -no-fast-install disable the fast-install mode
+ -no-install link a not-installable executable
+ -no-undefined declare that a library does not refer to external symbols
+ -o OUTPUT-FILE create OUTPUT-FILE from the specified objects
+ -objectlist FILE Use a list of object files found in FILE to specify objects
+ -precious-files-regex REGEX
+ don't remove output files matching REGEX
+ -release RELEASE specify package release information
+ -rpath LIBDIR the created library will eventually be installed in LIBDIR
+ -R[ ]LIBDIR add LIBDIR to the runtime path of programs and libraries
+ -static do not do any dynamic linking of libtool libraries
+ -version-info CURRENT[:REVISION[:AGE]]

+Every other argument is treated as a filename. Files ending in \`.la' are
+treated as uninstalled libtool libraries, other files are standard or library
+object files.
+
+If the OUTPUT-FILE ends in \`.la', then a libtool library is created,
+only library objects (\`.lo' files) may be specified, and \`-rpath' is
+required, except when creating a convenience library.

+//
+// #define switches
+// SIGSLOT_PURE_ISO - Define this to force ISO C++ compliance. This also disables
+// all of the thread safety support on platforms where it is
+// available.
+//
+// SIGSLOT_USE_POSIX_THREADS - Force use of Posix threads when using a C++ compiler other than
+// gcc on a platform that supports Posix threads. (When using gcc,
+// this is the default - use SIGSLOT_PURE_ISO to disable this if
+// necessary)
+//
+// SIGSLOT_DEFAULT_MT_POLICY - Where thread support is enabled, this defaults to multi_threaded_global.
+// Otherwise, the default is single_threaded. #define this yourself to
+// override the default. In pure ISO mode, anything other than
+// single_threaded will cause a compiler error.
+//
+// PLATFORM NOTES
+//
+// Win32 - On Win32, the WIN32 symbol must be #defined. Most mainstream
+// compilers do this by default, but you may need to define it
+// yourself if your build environment is less standard. This causes
+// the Win32 thread support to be compiled in and used automatically.
+//
+// Unix/Linux/BSD, etc. - If you're using gcc, it is assumed that you have Posix threads
+// available, so they are used automatically. You can override this
+// (as under Windows) with the SIGSLOT_PURE_ISO switch. If you're using
+// something other than gcc but still want to use Posix threads, you
+// need to #define SIGSLOT_USE_POSIX_THREADS.
+//
+// ISO C++ - If none of the supported platforms are detected, or if
+// SIGSLOT_PURE_ISO is defined, all multithreading support is turned off,
+// along with any code that might cause a pure ISO C++ environment to
+// complain. Before you ask, gcc -ansi -pedantic won't compile this
+// library, but gcc -ansi is fine. Pedantic mode seems to throw a lot of
+// errors that aren't really there. If you feel like investigating this,
+// please contact the author.
+//
+//
+// THREADING MODES
+//
+// single_threaded - Your program is assumed to be single threaded from the point of view
+// of signal/slot usage (i.e. all objects using signals and slots are
+// created and destroyed from a single thread). Behaviour if objects are
+// destroyed concurrently is undefined (i.e. you'll get the occasional
+// segmentation fault/memory exception).
+//
+// multi_threaded_global - Your program is assumed to be multi threaded. Objects using signals and
+// slots can be safely created and destroyed from any thread, even when
+// connections exist. In multi_threaded_global mode, this is achieved by a
+// single global mutex (actually a critical section on Windows because they
+// are faster). This option uses less OS resources, but results in more
+// opportunities for contention, possibly resulting in more context switches
+// than are strictly necessary.
+//
+// multi_threaded_local - Behaviour in this mode is essentially the same as multi_threaded_global,
+// except that each signal, and each object that inherits has_slots, all
+// have their own mutex/critical section. In practice, this means that
+// mutex collisions (and hence context switches) only happen if they are
+// absolutely essential. However, on some platforms, creating a lot of
+// mutexes can slow down the whole OS, so use this option with care.

+/////////////////////////////////////////////////////////////////////
+//
+// TASK
+//
+/////////////////////////////////////////////////////////////////////
+//
+// Task is a state machine infrastructure. States are pushed forward by
+// pushing forwards a TaskRunner that holds on to all Tasks. The purpose
+// of Task is threefold:
+//
+// (1) It manages ongoing work on the UI thread. Multitasking without
+// threads, keeping it easy, keeping it real. :-) It does this by
+// organizing a set of states for each task. When you return from your
+// Process*() function, you return an integer for the next state. You do
+// not go onto the next state yourself. Every time you enter a state,
+// you check to see if you can do anything yet. If not, you return
+// STATE_BLOCKED. If you _could_ do anything, do not return
+// STATE_BLOCKED - even if you end up in the same state, return
+// STATE_mysamestate. When you are done, return STATE_DONE and then the
+// task will self-delete sometimea afterwards.
+//
+// (2) It helps you avoid all those reentrancy problems when you chain
+// too many triggers on one thread. Basically if you want to tell a task
+// to process something for you, you feed your task some information and
+// then you Wake() it. Don't tell it to process it right away. If it
+// might be working on something as you send it infomration, you may want
+// to have a queue in the task.
+//
+// (3) Finally it helps manage parent tasks and children. If a parent
+// task gets aborted, all the children tasks are too. The nice thing
+// about this, for example, is if you have one parent task that
+// represents, say, and Xmpp connection, then you can spawn a whole bunch
+// of infinite lifetime child tasks and now worry about cleaning them up.
+// When the parent task goes to STATE_DONE, the task engine will make
+// sure all those children are aborted and get deleted.
+//
+// Notice that Task has a few built-in states, e.g.,
+//
+// STATE_INIT - the task isn't running yet
+// STATE_START - the task is in its first state
+// STATE_RESPONSE - the task is in its second state
+// STATE_DONE - the task is done
+//
+// STATE_ERROR - indicates an error - we should audit the error code in
+// light of any usage of it to see if it should be improved. When I
+// first put down the task stuff I didn't have a good sense of what was
+// needed for Abort and Error, and now the subclasses of Task will ground
+// the design in a stronger way.
+//
+// STATE_NEXT - the first undefined state number. (like WM_USER) - you
+// can start defining more task states there.
+//
+// When you define more task states, just override Process(int state) and
+// add your own switch statement. If you want to delegate to
+// Task::Process, you can effectively delegate to its switch statement.
+// No fancy method pointers or such - this is all just pretty low tech,
+// easy to debug, and fast.
+//
+// Also notice that Task has some primitive built-in timeout functionality.
+//
+// A timeout is defined as "the task stays in STATE_BLOCKED longer than
+// timeout_seconds_."
+//
+// Descendant classes can override this behavior by calling the
+// various protected methods to change the timeout behavior. For
+// instance, a descendand might call SuspendTimeout() when it knows
+// that it isn't waiting for anything that might timeout, but isn't
+// yet in the STATE_DONE state.

+// can have it nested arbitrarily deep under an XmppClient and it can
+// still find the XMPP services.
+//
+// Tasks register themselves to listen to particular kinds of stanzas
+// that are sent out by the client. Rather than processing stanzas
+// right away, they should decide if they own the sent stanza,
+// and if so, queue it and Wake() the task, or if a stanza does not belong
+// to you, return false right away so the next XmppTask can take a crack.
+// This technique (synchronous recognize, but asynchronous processing)
+// allows you to have arbitrary logic for recognizing stanzas yet still,
+// for example, disconnect a client while processing a stanza -
+// without reentrancy problems.
