-                 SCons - a software construction tool
-
-                         Version 2.0.1
-
-
-This is an alpha release of the SCons build engine, a Python extension
-module for building software (and other files).  The SCons build engine
-manages dependencies and executes commands or Python functions to update
-out-of-date files (or other objects).
-
-
-LATEST VERSION
-==============
-
-Before going further, you can check that this package you have is
-the latest version by checking the SCons download page at:
-
-        http://www.scons.org/download.html
-
-
-ABOUT SCONS PACKAGES
-====================
-
-The complete SCons system is comprised of three separate packages:
-
-    scons
-        The scons script itself, plus the SCons build engine
-        installed into an SCons-specific library directory.
-
-    python-scons [THIS PACKAGE]
-        The SCons build engine, installed into the standard
-        Python library directory.
-
-    scons-script
-        Only the scons script itself.
-
-Depending on what you want to do with SCons, you may need to install
-additional (or other) packages:
-
-    If you just want to use scons (the script) to build software:
-
-        Do not install this package.  Install the scons package instead,
-        which contains a copy of both the script and the build engine.
-        You will not need to install any other packages.
-
-    If you do NOT want to use the scons script, but you want to use the
-    SCons build engine in other Python software:
-
-        Install this package.  You do not need to install any other
-        packages.
-
-    If you want to use the scons script AND you want to use the SCons
-    build engine in other Python software:
-
-        Install this package AND the scons package.
-
-        Note that this installs two separate copies of the build engine,
-        one (in an SCons-specific library directory) used by the scons
-        script itself and one (in the standard Python library) used by
-        other software.  This allows you the flexibility to upgrade
-        one build engine without affecting the other.
-
-    If you want the scons script and other Python software to use the
-    same version of the build engine:
-
-        Install this package AND the scons-script package.
-
-
-INSTALLATION
-============
-
-To install this package, simply run the provided Python-standard setup
-script as follows:
-
-        # python setup.py
-
-You should have system installation privileges (that is, "root" or
-"Administrator") when running the setup.py script.
-

+Specifies that

+will maintain a cache of derived files in
+<varname>cache_dir</varname>.
+The derived files in the cache will be shared
+among all the builds using the same
+&f-CacheDir;
+call.
+Specifying a
+<varname>cache_dir</varname>
+of
+<literal>None</literal>
+disables derived file caching.
+
+Calling
+<function>env.CacheDir</function>()
+will only affect targets built

+Calling
+&f-CacheDir;
+sets a global default
+that will be used by all targets built
+through construction environments
+that do
+<emphasis>not</emphasis>
+have an
+<function>env.CacheDir</function>()
+specified.
+
+When a
+<function>CacheDir</function>()
+is being used and
+&scons;
+finds a derived file that needs to be rebuilt,
+it will first look in the cache to see if a
+derived file has already been built
+from identical input files and an identical build action
+(as incorporated into the MD5 build signature).
+If so,
+&scons;
+will retrieve the file from the cache.
+If the derived file is not present in the cache,
+&scons;
+will rebuild it and
+then place a copy of the built file in the cache
+(identified by its MD5 build signature),
+so that it may be retrieved by other
+builds that need to build the same derived file
+from identical inputs.
+
+Use of a specified
+&f-CacheDir;
+may be disabled for any invocation
+by using the
+<option>--cache-disable</option>
+option.
+
+If the
+<option>--cache-force</option>
+option is used,
+&scons;
+will place a copy of
+<emphasis>all</emphasis>
+derived files in the cache,
+even if they already existed
+and were not built by this invocation.
+This is useful to populate a cache
+the first time
+&f-CacheDir;
+is added to a build,
+or after using the
+<option>--cache-disable</option>
+option.
+
+When using
+&f-CacheDir;,
+&scons;
+will report,
+"Retrieved `file' from cache,"
+unless the
+<option>--cache-show</option>
+option is being used.
+When the
+<option>--cache-show</option>
+option is used,
+&scons;
+will print the action that
+<emphasis>would</emphasis>
+have been used to build the file,
+without any indication that
+the file was actually retrieved from the cache.
+This is useful to generate build logs
+that are equivalent regardless of whether
+a given derived file has been built in-place
+or retrieved from the cache.
+
+The
+&f-link-NoCache;
+method can be used to disable caching of specific files.  This can be
+useful if inputs and/or outputs of some tool are impossible to
+predict or prohibitively large.

+(targets, files_or_dirs)

+<summary>
+This specifies a list of files or directories which should be removed
+whenever the targets are specified with the
+<option>-c</option>
+command line option.
+The specified targets may be a list
+or an individual target.
+Multiple calls to
+&f-Clean;
+are legal,
+and create new targets or add files and directories to the
+clean list for the specified targets.
+
+Multiple files or directories should be specified
+either as separate arguments to the
+&f-Clean;
+method, or as a list.
+&f-Clean;
+will also accept the return value of any of the construction environment
+Builder methods.
+Examples:
+
+The related
+&f-link-NoClean;
+function overrides calling
+&f-Clean;
+for the same target,
+and any targets passed to both functions will
+<emphasis>not</emphasis>
+be removed by the

+option.
+
+Examples:
+
+<example>
+Clean('foo', ['bar', 'baz'])
+Clean('dist', env.Program('hello', 'hello.c'))
+Clean(['foo', 'bar'], 'something_else_to_clean')
+</example>
+
+In this example,
+installing the project creates a subdirectory for the documentation.
+This statement causes the subdirectory to be removed
+if the project is deinstalled.

+Example:
+
+<example>
+env2 = env.Clone()

+def MyTool(env): env['FOO'] = 'bar'
+env4 = env.Clone(tools = ['msvc', MyTool])
+</example>
+
+The

+<arguments>
+(target, source, action, [key=val, ...])
+</arguments>
+<summary>
+Executes a specific action
+(or list of actions)
+to build a target file or files.
+This is more convenient
+than defining a separate Builder object
+for a single special-case build.
+
+As a special case, the
+<varname>source_scanner</varname>
+keyword argument can
+be used to specify
+a Scanner object
+that will be used to scan the sources.
+(The global
+<literal>DirScanner</literal>
+object can be used
+if any of the sources will be directories
+that must be scanned on-disk for
+changes to files that aren't
+already specified in other Builder of function calls.)
+
+Any other keyword arguments specified override any
+same-named existing construction variables.
+
+An action can be an external command,
+specified as a string,
+or a callable Python object;
+see "Action Objects," below,
+for more complete information.
+Also note that a string specifying an external command
+may be preceded by an
+<literal>@</literal>
+(at-sign)
+to suppress printing the command in question,
+or by a
+<literal>-</literal>
+(hyphen)
+to ignore the exit status of the external command.
+
+Examples:
+
+<example>
+env.Command('foo.out', 'foo.in',
+            "$FOO_BUILD &lt; $SOURCES &gt; $TARGET")
+
+env.Command('bar.out', 'bar.in',
+            ["rm -f $TARGET",
+             "$BAR_BUILD &lt; $SOURCES &gt; $TARGET"],
+            ENV = {'PATH' : '/usr/local/bin/'})
+
+def rename(env, target, source):
+    import os
+    os.rename('.tmp', str(target[0]))
+
+env.Command('baz.out', 'baz.in',
+            ["$BAZ_BUILD &lt; $SOURCES &gt; .tmp",
+	     rename ])
+</example>
+
+Note that the
+&f-Command;
+function will usually assume, by default,
+that the specified targets and/or sources are Files,
+if no other part of the configuration
+identifies what type of entry it is.
+If necessary, you can explicitly specify
+that targets or source nodes should
+be treated as directoriese
+by using the
+&f-link-Dir;
+or
+<function>env.Dir</function>()
+functions.
+
+Examples:
+
+<example>
+env.Command('ddd.list', Dir('ddd'), 'ls -l $SOURCE > $TARGET')
+
+env['DISTDIR'] = 'destination/directory'
+env.Command(env.Dir('$DISTDIR')), None, make_distdir)
+</example>

+automatically create any directory necessary to hold a target file,
+so you normally don't need to create directories by hand.)

+
+In addition to the above already-available functions,
+the
+<varname>function</varname>
+argument may be an actual Python function
+that takes the following three arguments:
+
+<variablelist>
+<varlistentry>
+<term><parameter>dependency</parameter></term>
+<listitem>
+<para>
+The Node (file) which
+should cause the
+<varname>target</varname>
+to be rebuilt
+if it has "changed" since the last tme
+<varname>target</varname>
+was built.
+</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term><parameter>target</parameter></term>
+<listitem>
+<para>
+The Node (file) being built.
+In the normal case,
+this is what should get rebuilt
+if the
+<varname>dependency</varname>
+has "changed."
+</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term><parameter>prev_ni</parameter></term>
+<listitem>
+<para>
+Stored information about the state of the
+<varname>dependency</varname>
+the last time the
+<varname>target</varname>
+was built.
+This can be consulted to match various
+file characteristics
+such as the timestamp,
+size, or content signature.
+</para>
+</listitem>
+</varlistentry>
+</variablelist>
+
+The
+<varname>function</varname>
+should return a
+<literal>True</literal>
+(non-zero)
+value if the
+<varname>dependency</varname>
+has "changed" since the last time

+(indicating that the target should
+<emphasis>not</emphasis>
+be rebuilt).
+Note that the decision can be made
+using whatever criteria are appopriate.
+Ignoring some or all of the function arguments
+is perfectly normal.

+This can be helpful for collecting

+
+Examples:

+<example>
+foo = Object('foo.c')
+bar = Object('bar.c')
+
+# Because `foo' and `bar' are lists returned by the Object() Builder,
+# `objects' will be a list containing nested lists:

+
+# Passing such a list to another Builder is all right because

+Parses one or more strings containing
+typical command-line flags for GCC tool chains
+and returns a dictionary with the flag values
+separated into the appropriate SCons construction variables.
+This is intended as a companion to the
+&f-link-env-MergeFlags;
+method, but allows for the values in the returned dictionary
+to be modified, if necessary,
+before merging them into the construction environment.
+(Note that
+&f-env-MergeFlags;
+will call this method if its argument is not a dictionary,
+so it is usually not necessary to call

+directly unless you want to manipulate the values.)
+
+If the first character in any string is
+an exclamation mark (!),
+the rest of the string is executed as a command,
+and the output from the command is
+parsed as GCC tool chain command-line flags
+and added to the resulting dictionary.
+
+Flag values are translated accordig to the prefix found,
+and added to the following construction variables:

+as specified by the corresponding
+&f-SourceSignatures;
+setting.
+This "propagates" the status of a rebuilt file
+so that other "downstream" target files
+will always be rebuilt,
+even if the contents or the timestamp
+have not changed.
+
+<literal>"build"</literal>
+signatures are fastest because
+<literal>"content"</literal>
+(or
+<literal>"MD5"</literal>)
+signatures take longer to compute,
+but are more accurate than
+<literal>"timestamp"</literal>
+signatures,
+and can prevent unnecessary "downstream" rebuilds
+when a target file is rebuilt to the exact same contents
+as the previous build.
+The
+<literal>"source"</literal>
+setting provides the most consistent behavior
+when other target files may be rebuilt from
+both source and target input files.
+The default value is
+<literal>"source"</literal>.
+
+Because the default setting is
+<literal>"source"</literal>,
+using
+&f-SourceSignatures;
+is generally preferable to
+&f-TargetSignatures;,
+so that the up-to-date decision
+will be consistent for all files
+(or all files built with a specific construction environment).
+Use of
+&f-TargetSignatures;
+provides specific control for how built target files
+affect their "downstream" dependencies.

+<summary>
+The
+&f-Tool;
+form of the function
+returns a callable object
+that can be used to initialize
+a construction environment using the
+tools keyword of the Environment() method.
+The object may be called with a construction
+environment as an argument,
+in which case the object will
+add the necessary variables
+to the construction environment
+and the name of the tool will be added to the
+&cv-link-TOOLS;
+construction variable.
+
+Additional keyword arguments are passed to the tool's
+<function>generate</function>()
+method.
+
+Examples:
+
+<example>
+env = Environment(tools = [ Tool('msvc') ])
+
+env = Environment()
+t = Tool('msvc')
+t(env)  # adds 'msvc' to the TOOLS variable
+u = Tool('opengl', toolpath = ['tools'])
+u(env)  # adds 'opengl' to the TOOLS variable
+</example>
+
+The
+&f-env-Tool;
+form of the function
+applies the callable object for the specified tool
+<varname>string</varname>
+to the environment through which the method was called.
+
+Additional keyword arguments are passed to the tool's
+<function>generate</function>()
+method.
+
+<example>
+env.Tool('gcc')
+env.Tool('opengl', toolpath = ['build/tools'])

+<summary>
+Returns a Node object representing the specified Python value.  Value
+Nodes can be used as dependencies of targets.  If the result of
+calling
+<function>str</function>(<varname>value</varname>)
+changes between SCons runs, any targets depending on
+<function>Value</function>(<varname>value</varname>)
+will be rebuilt.
+(This is true even when using timestamps to decide if
+files are up-to-date.)
+When using timestamp source signatures, Value Nodes'
+timestamps are equal to the system time when the Node is created.
+
+The returned Value Node object has a
+<function>write</function>()
+method that can be used to "build" a Value Node
+by setting a new value.
+The optional
+<varname>built_value</varname>
+argument can be specified
+when the Value Node is created
+to indicate the Node should already be considered
+"built."
+There is a corresponding
+<function>read</function>()
+method that will return the built value of the Node.
+
+Examples:
+
+<example>
+env = Environment()
+
+def create(target, source, env):
+    # A function that will write a 'prefix=$SOURCE'
+    # string into the file name specified as the

+    f = open(str(target[0]), 'wb')
+    f.write('prefix=' + source[0].get_contents())
+
+# Fetch the prefix= argument, if any, from the command

+prefix = ARGUMENTS.get('prefix', '/usr/local')
+
+# Attach a .Config() builder for the above function action

+env.Config(target = 'package-config', source = Value(prefix))
+
+def build_value(target, source, env):
+    # A function that "builds" a Python Value by updating
+    # the the Python value with the contents of the file
+    # specified as the source of the Builder call ($SOURCE).
+    target[0].write(source[0].get_contents())
+
+output = env.Value('before')
+input = env.Value('after')
+
+# Attach a .UpdateValue() builder for the above function
+# action to the construction environment.
+env['BUILDERS']['UpdateValue'] = Builder(action = build_value)
+env.UpdateValue(target = Value(output), source = Value(input))

+
+<scons_function name="VariantDir">
+<arguments>
+(variant_dir, src_dir, [duplicate])
+</arguments>
+<summary>
+Use the
+&f-VariantDir;
+function to create a copy of your sources in another location:
+if a name under
+<varname>variant_dir</varname>
+is not found but exists under
+<varname>src_dir</varname>,
+the file or directory is copied to
+<varname>variant_dir</varname>.
+Target files can be built in a different directory
+than the original sources by simply refering to the sources (and targets)
+within the variant tree.
+
+&f-VariantDir;
+can be called multiple times with the same
+<varname>src_dir</varname>
+to set up multiple builds with different options
+(<varname>variants</varname>).
+The
+<varname>src_dir</varname>
+location must be in or underneath the SConstruct file's directory, and
+<varname>variant_dir</varname>
+may not be underneath
+<varname>src_dir</varname>.
+<!--
+TODO: Can the above restrictions be clarified or relaxed?
+TODO: The latter restriction is clearly not completely right;
+TODO: src_dir = '.' works fine with a build dir under it.
+-->
+
+The default behavior is for
+&scons;
+to physically duplicate the source files in the variant tree.
+Thus, a build performed in the variant tree is guaranteed to be identical
+to a build performed in the source tree even if
+intermediate source files are generated during the build,
+or preprocessors or other scanners search for included files
+relative to the source file,
+or individual compilers or other invoked tools are hard-coded
+to put derived files in the same directory as source files.
+
+If possible on the platform,
+the duplication is performed by linking rather than copying;
+see also the
+<option>--duplicate</option>
+command-line option.
+Moreover, only the files needed for the build are duplicated;
+files and directories that are not used are not present in
+<varname>variant_dir</varname>.
+
+Duplicating the source tree may be disabled by setting the
+<literal>duplicate</literal>
+argument to
+<literal>0</literal>
+(zero).
+This will cause
+&scons;
+to invoke Builders using the path names of source files in
+<varname>src_dir</varname>
+and the path names of derived files within
+<varname>variant_dir</varname>.
+This is always more efficient than
+<literal>duplicate=1</literal>,
+and is usually safe for most builds
+(but see above for cases that may cause problems).
+
+Note that
+&f-VariantDir;
+works most naturally with a subsidiary SConscript file.
+However, you would then call the subsidiary SConscript file
+not in the source directory, but in the
+<varname>variant_dir</varname>,
+regardless of the value of
+<literal>duplicate</literal>.
+This is how you tell
+&scons;
+which variant of a source tree to build:
+
+<example>
+# run src/SConscript in two variant directories
+VariantDir('build/variant1', 'src')
+SConscript('build/variant1/SConscript')
+VariantDir('build/variant2', 'src')
+SConscript('build/variant2/SConscript')
+</example>
+
+See also the
+&f-link-SConscript;
+function, described above,
+for another way to specify a variant directory
+in conjunction with calling a subsidiary SConscript file.
+
+Examples:
+
+<example>
+# use names in the build directory, not the source directory
+VariantDir('build', 'src', duplicate=0)
+Program('build/prog', 'build/source.c')
+</example>
+
+<example>
+# this builds both the source and docs in a separate subtree
+VariantDir('build', '.', duplicate=0)
+SConscript(dirs=['build/src','build/doc'])
+</example>
+
+<example>
+# same as previous example, but only uses SConscript
+SConscript(dirs='src', variant_dir='build/src', duplicate=0)
+SConscript(dirs='doc', variant_dir='build/doc', duplicate=0)
+</example>

+<scons_function name="FindPathDirs">
+<arguments signature="global">
+(variable)
+</arguments>
+<summary>
+Returns a function
+(actually a callable Python object)
+intended to be used as the
+<varname>path_function</varname>
+of a Scanner object.
+The returned object will look up the specified
+<varname>variable</varname>
+in a construction environment
+and treat the construction variable's value as a list of
+directory paths that should be searched
+(like
+&cv-link-CPPPATH;,
+&cv-link-LIBPATH;,
+etc.).
+
+Note that use of
+&f-FindPathDirs;
+is generally preferable to
+writing your own
+<varname>path_function</varname>
+for the following reasons:
+1) The returned list will contain all appropriate directories
+found in source trees
+(when
+&f-link-VariantDir;
+is used)
+or in code repositories
+(when
+&f-Repository;
+or the
+<option>-Y</option>
+option are used).
+2) scons will identify expansions of
+<varname>variable</varname>
+that evaluate to the same list of directories as,
+in fact, the same list,
+and avoid re-scanning the directories for files,
+when possible.
+
+Example:
+
+<example>
+def my_scan(node, env, path, arg):
+    # Code to scan file contents goes here...
+    return include_files
+
+scanner = Scanner(name = 'myscanner',
+                  function = my_scan,
+                  path_function = FindPathDirs('MYPATH'))
+</example>
+</summary>

+<summary>
+This function adds a new command-line option to be recognized.
+The specified
+<varname>arguments</varname>
+are the same as supported by the standard Python
+<function>optparse.add_option</function>()
+method (with a few additional capabilities noted below);
+see the documentation for
+<literal>optparse</literal>
+for a thorough discussion of its option-processing capabities.
+
+In addition to the arguments and values supported by the
+<function>optparse.add_option</function>()
+method,
+the SCons
+&f-AddOption;
+function allows you to set the
+<literal>nargs</literal>
+keyword value to
+<literal>'?'</literal>
+(a string with just the question mark)
+to indicate that the specified long option(s) take(s) an
+<emphasis>optional</emphasis>
+argument.
+When
+<literal>nargs = '?'</literal>
+is passed to the
+&f-AddOption;
+function, the
+<literal>const</literal>
+keyword argument
+may be used to supply the "default"
+value that should be used when the
+option is specified on the command line
+without an explicit argument.
+
+If no
+<literal>default=</literal>
+keyword argument is supplied when calling
+&f-AddOption;,
+the option will have a default value of
+<literal>None</literal>.
+
+Once a new command-line option has been added with
+&f-AddOption;,
+the option value may be accessed using
+&f-GetOption;
+or
+<function>env.GetOption</function>().
+The value may also be set, using
+&f-SetOption;
+or
+<function>env.SetOption</function>(),
+if conditions in a
+&SConscript;
+require overriding any default value.
+Note, however, that a
+value specified on the command line will
+<emphasis>always</emphasis>
+override a value set by any SConscript file.
+
+Any specified
+<literal>help=</literal>
+strings for the new option(s)
+will be displayed by the
+<option>-H</option>
+or
+<option>-h</option>
+options
+(the latter only if no other help text is
+specified in the SConscript files).
+The help text for the local options specified by
+&f-AddOption;
+will appear below the SCons options themselves,
+under a separate
+<literal>Local Options</literal>
+heading.
+The options will appear in the help text
+in the order in which the
+&f-AddOption;
+calls occur.
+
+Example:
+
+<example>
+AddOption('--prefix',
+          dest='prefix',
+          nargs=1, type='string',
+          action='store',
+          metavar='DIR',
+          help='installation prefix')
+env = Environment(PREFIX = GetOption('prefix'))

+<summary>
+Returns a list of exceptions for the
+actions that failed while
+attempting to build targets.
+Each element in the returned list is a
+<classname>BuildError</classname>
+object
+with the following attributes
+that record various aspects
+of the build failure:
+
+<literal>.node</literal>
+The node that was being built
+when the build failure occurred.
+
+<literal>.status</literal>
+The numeric exit status
+returned by the command or Python function
+that failed when trying to build the
+specified Node.
+
+<literal>.errstr</literal>
+The SCons error string
+describing the build failure.
+(This is often a generic
+message like "Error 2"
+to indicate that an executed
+command exited with a status of 2.)
+
+<literal>.filename</literal>
+The name of the file or
+directory that actually caused the failure.
+This may be different from the
+<literal>.node</literal>
+attribute.
+For example,
+if an attempt to build a target named
+<filename>sub/dir/target</filename>
+fails because the
+<filename>sub/dir</filename>
+directory could not be created,
+then the
+<literal>.node</literal>
+attribute will be
+<filename>sub/dir/target</filename>
+but the
+<literal>.filename</literal>
+attribute will be
+<filename>sub/dir</filename>.
+
+<literal>.executor</literal>
+The SCons Executor object
+for the target Node
+being built.
+This can be used to retrieve
+the construction environment used
+for the failed action.
+
+<literal>.action</literal>
+The actual SCons Action object that failed.
+This will be one specific action
+out of the possible list of
+actions that would have been
+executed to build the target.
+
+<literal>.command</literal>
+The actual expanded command that was executed and failed,
+after expansion of
+&cv-link-TARGET;,
+&cv-link-SOURCE;,
+and other construction variables.
+
+Note that the
+&f-GetBuildFailures;
+function
+will always return an empty list
+until any build failure has occurred,
+which means that
+&f-GetBuildFailures;
+will always return an empty list
+while the
+&SConscript;
+files are being read.
+Its primary intended use is
+for functions that will be
+executed before SCons exits
+by passing them to the
+standard Python
+<function>atexit.register</function>()
+function.
+Example:
+
+<example>
+import atexit
+
+def print_build_failures():
+    from SCons.Script import GetBuildFailures
+    for bf in GetBuildFailures():
+        print "%s failed: %s" % (bf.node, bf.errstr)

+<summary>
+Allows SCons to show progress made during the build
+by displaying a string or calling a function while
+evaluating Nodes (e.g. files).
+
+If the first specified argument is a Python callable
+(a function or an object that has a
+<function>__call__</function>()
+method),
+the function will be called
+once every
+<varname>interval</varname>
+times a Node is evaluated.
+The callable will be passed the evaluated Node
+as its only argument.
+(For future compatibility,
+it's a good idea to also add
+<literal>*args</literal>
+and
+<literal>**kw</literal>
+as arguments to your function or method.
+This will prevent the code from breaking
+if SCons ever changes the interface
+to call the function with additional arguments in the future.)
+
+An example of a simple custom progress function
+that prints a string containing the Node name
+every 10 Nodes:
+
+<example>
+def my_progress_function(node, *args, **kw):
+    print 'Evaluating node %s!' % node
+Progress(my_progress_function, interval=10)
+</example>
+
+A more complicated example of a custom progress display object
+that prints a string containing a count
+every 100 evaluated Nodes.
+Note the use of
+<literal>\r</literal>
+(a carriage return)
+at the end so that the string
+will overwrite itself on a display:
+
+<example>
+import sys
+class ProgressCounter(object):
+    count = 0
+    def __call__(self, node, *args, **kw):
+        self.count += 100
+        sys.stderr.write('Evaluated %s nodes\r' % self.count)
+Progress(ProgressCounter(), interval=100)
+</example>
+
+If the first argument
+&f-link-Progress;
+is a string,
+the string will be displayed
+every
+<varname>interval</varname>
+evaluated Nodes.
+The default is to print the string on standard output;
+an alternate output stream
+may be specified with the
+<literal>file=</literal>
+argument.
+The following will print a series of dots
+on the error output,
+one dot for every 100 evaluated Nodes:
+
+<example>
+import sys
+Progress('.', interval=100, file=sys.stderr)
+</example>
+
+If the string contains the verbatim substring
+&cv-TARGET;,
+it will be replaced with the Node.
+Note that, for performance reasons, this is
+<emphasis>not</emphasis>
+a regular SCons variable substition,
+so you can not use other variables
+or use curly braces.
+The following example will print the name of
+every evaluated Node,
+using a
+<literal>\r</literal>
+(carriage return) to cause each line to overwritten by the next line,
+and the
+<literal>overwrite=</literal>
+keyword argument to make sure the previously-printed
+file name is overwritten with blank spaces:
+
+<example>
+import sys
+Progress('$TARGET\r', overwrite=True)
+</example>
+
+If the first argument to
+&f-Progress;
+is a list of strings,
+then each string in the list will be displayed
+in rotating fashion every
+<varname>interval</varname>
+evaluated Nodes.
+This can be used to implement a "spinner"
+on the user's screen as follows:
+
+<example>
+Progress(['-\r', '\\\r', '|\r', '/\r'], interval=5)
+</example>

+<summary>
+This specifies a list of default targets,
+which will be built by
+&scons;
+if no explicit targets are given on the command line.
+Multiple calls to
+&f-Default;
+are legal,
+and add to the list of default targets.
+
+Multiple targets should be specified as
+separate arguments to the
+&f-Default;
+method, or as a list.
+&f-Default;
+will also accept the Node returned by any
+of a construction environment's
+builder methods.
+
+Examples:
+
+<example>
+Default('foo', 'bar', 'baz')
+env.Default(['a', 'b', 'c'])
+hello = env.Program('hello', 'hello.c')
+env.Default(hello)
+</example>
+
+An argument to
+&f-Default;
+of
+<literal>None</literal>
+will clear all default targets.
+Later calls to
+&f-Default;
+will add to the (now empty) default-target list
+like normal.
+
+The current list of targets added using the

+<summary>
+This tells
+&scons;
+to export a list of variables from the current
+SConscript file to all other SConscript files.
+The exported variables are kept in a global collection,
+so subsequent calls to
+&f-Export;
+will over-write previous exports that have the same name.
+Multiple variable names can be passed to
+&f-Export;
+as separate arguments or as a list.
+Keyword arguments can be used to provide names and their values.
+A dictionary can be used to map variables to a different name when exported.
+Both local variables and global variables can be exported.
+
+Examples:
+
+<example>
+env = Environment()
+# Make env available for all SConscript files to Import().
+Export("env")
+
+package = 'my_name'
+# Make env and package available for all SConscript files:.
+Export("env", "package")
+
+# Make env and package available for all SConscript files:
+Export(["env", "package"])
+
+# Make env available using the name debug:
+Export(debug = env)
+
+# Make env available using the name debug:
+Export({"debug":env})
+</example>
+
+Note that the
+&f-SConscript;
+function supports an
+<varname>exports</varname>
+argument that makes it easier to to export a variable or
+set of variables to a single SConscript file.

+&f-link-SConscript;.
+Variables exported by

+However, the values returned
+are still the values of the variables in the named

+
+# Returns the values of the Python variables 'foo' and 'bar'.

+<summary>
+This tells
+&scons;
+to execute
+one or more subsidiary SConscript (configuration) files.
+Any variables returned by a called script using
+&f-link-Return;
+will be returned by the call to
+&f-SConscript;.
+There are two ways to call the
+&f-SConscript;
+function.
+
+The first way you can call
+&f-SConscript;
+is to explicitly specify one or more
+<varname>scripts</varname>
+as the first argument.
+A single script may be specified as a string;
+multiple scripts must be specified as a list
+(either explicitly or as created by
+a function like
+&f-Split;).
+Examples:
+<example>
+SConscript('SConscript')      # run SConscript in the current directory
+SConscript('src/SConscript')  # run SConscript in the src directory
+SConscript(['src/SConscript', 'doc/SConscript'])
+config = SConscript('MyConfig.py')
+</example>
+
+The second way you can call
+&f-SConscript;
+is to specify a list of (sub)directory names
+as a
+<literal>dirs=</literal><varname>subdirs</varname>
+keyword argument.
+In this case,
+&scons;
+will, by default,
+execute a subsidiary configuration file named
+&SConscript;
+in each of the specified directories.
+You may specify a name other than
+&SConscript;
+by supplying an optional
+<literal>name=</literal><varname>script</varname>
+keyword argument.
+The first three examples below have the same effect
+as the first three examples above:
+<example>
+SConscript(dirs='.')      # run SConscript in the current directory
+SConscript(dirs='src')    # run SConscript in the src directory
+SConscript(dirs=['src', 'doc'])
+SConscript(dirs=['sub1', 'sub2'], name='MySConscript')
+</example>
+
+The optional
+<varname>exports</varname>
+argument provides a list of variable names or a dictionary of
+named values to export to the
+<varname>script(s)</varname>.
+These variables are locally exported only to the specified
+<varname>script(s)</varname>,
+and do not affect the global pool of variables used by the
+&f-Export;
+function.
+<!-- If multiple dirs are provided, each script gets a fresh export. -->
+The subsidiary
+<varname>script(s)</varname>
+must use the
+&f-link-Import;
+function to import the variables.
+Examples:
+<example>
+foo = SConscript('sub/SConscript', exports='env')
+SConscript('dir/SConscript', exports=['env', 'variable'])
+SConscript(dirs='subdir', exports='env variable')
+SConscript(dirs=['one', 'two', 'three'], exports='shared_info')
+</example>
+
+If the optional
+<varname>variant_dir</varname>
+argument is present, it causes an effect equivalent to the
+&f-link-VariantDir;
+method described below.
+(If
+<varname>variant_dir</varname>
+is not present, the
+<!-- <varname>src_dir</varname> and -->
+<varname>duplicate</varname>
+<!-- arguments are ignored.) -->
+argument is ignored.)
+The
+<varname>variant_dir</varname>
+<!--
+and
+<varname>src_dir</varname>
+arguments are interpreted relative to the directory of the calling
+-->
+argument is interpreted relative to the directory of the calling
+&SConscript;
+file.
+See the description of the
+&f-VariantDir;
+function below for additional details and restrictions.
+
+If
+<varname>variant_dir</varname>
+is present,
+<!--
+but
+<varname>src_dir</varname>
+is not,
+-->
+the source directory is the directory in which the
+&SConscript;
+file resides and the
+&SConscript;
+file is evaluated as if it were in the
+<varname>variant_dir</varname>
+directory:
+<example>
+SConscript('src/SConscript', variant_dir = 'build')
+</example>
+
+is equivalent to
+
+<example>
+VariantDir('build', 'src')
+SConscript('build/SConscript')
+</example>
+
+This later paradigm is often used when the sources are
+in the same directory as the
+&SConstruct;:
+
+<example>
+SConscript('SConscript', variant_dir = 'build')
+</example>
+
+is equivalent to
+
+<example>
+VariantDir('build', '.')
+SConscript('build/SConscript')
+</example>
+
+<!--
+If
+<varname>variant_dir</varname>
+and"
+<varname>src_dir</varname>
+are both present,
+xxxxx everything is in a state of confusion.
+<example>
+SConscript(dirs = 'src', variant_dir = 'build', src_dir = '.')
+runs src/SConscript in build/src, but
+SConscript(dirs = 'lib', variant_dir = 'build', src_dir = 'src')
+runs lib/SConscript (in lib!).  However,
+SConscript(dirs = 'src', variant_dir = 'build', src_dir = 'src')
+runs src/SConscript in build.  Moreover,
+SConscript(dirs = 'src/lib', variant_dir = 'build', src_dir = 'src')
+runs src/lib/SConscript in build/lib.  Moreover,
+SConscript(dirs = 'build/src/lib', variant_dir = 'build', src_dir = 'src')
+can't find build/src/lib/SConscript, even though it ought to exist.
+</example>
+is equivalent to
+<example>
+????????????????
+</example>
+and what about this alternative?
+TODO??? SConscript('build/SConscript', src_dir='src')
+-->
+
+Here are some composite examples:
+
+<example>
+# collect the configuration information and use it to build src and doc
+shared_info = SConscript('MyConfig.py')
+SConscript('src/SConscript', exports='shared_info')
+SConscript('doc/SConscript', exports='shared_info')
+</example>
+
+<example>
+# build debugging and production versions.  SConscript
+# can use Dir('.').path to determine variant.
+SConscript('SConscript', variant_dir='debug', duplicate=0)
+SConscript('SConscript', variant_dir='prod', duplicate=0)
+</example>
+
+<example>
+# build debugging and production versions.  SConscript
+# is passed flags to use.
+opts = { 'CPPDEFINES' : ['DEBUG'], 'CCFLAGS' : '-pgdb' }
+SConscript('SConscript', variant_dir='debug', duplicate=0, exports=opts)
+opts = { 'CPPDEFINES' : ['NODEBUG'], 'CCFLAGS' : '-O' }
+SConscript('SConscript', variant_dir='prod', duplicate=0, exports=opts)
+</example>
+
+<example>

+SConscript('src/SConscript', variant_dir='build/x86', duplicate=0)

+<summary>
+Specifies the exceptions that will be allowed
+when expanding construction variables.
+By default,
+any construction variable expansions that generate a
+<literal>NameError</literal>
+or
+<literal>IndexError</literal>
+exception will expand to a
+<literal>''</literal>
+(a null string) and not cause scons to fail.
+All exceptions not in the specified list
+will generate an error message
+and terminate processing.
+
+If
+&f-AllowSubstExceptions;
+is called multiple times,
+each call completely overwrites the previous list
+of allowed exceptions.
+
+Example:
+
+<example>
+# Requires that all construction variable names exist.
+# (You may wish to do this if you want to enforce strictly
+# that all construction variables must be defined before use.)
+AllowSubstExceptions()
+
+# Also allow a string containing a zero-division expansion
+# like '${1 / 0}' to evalute to ''.
+AllowSubstExceptions(IndexError, NameError, ZeroDivisionError)
