+

+
+    If you allow multiple builds to update the
+    shared cache directory simultaneously,
+    two builds that occur at the same time
+    can sometimes start "racing"
+    with one another to build the same files
+    in the same order.
+    If, for example,
+    you are linking multiple files into an executable program:
+
+    </para>

+

+
+    But if two such builds take place simultaneously,
+    they may each look in the cache at nearly the same
+    time and both decide that <filename>f1.o</filename>
+    must be rebuilt and pushed into the shared cache directory,
+    then both decide that <filename>f2.o</filename>
+    must be rebuilt (and pushed into the shared cache directory),
+    then both decide that <filename>f3.o</filename>
+    must be rebuilt...
+    This won't cause any actual build problems--both
+    builds will succeed,
+    generate correct output files,
+    and populate the cache--but
+    it does represent wasted effort.

+    <para>
+
+    To alleviate such contention for the cache,

+    specific files in your configuration.
+    For example, if you only want to put
+    executable files in a central cache,
+    but not the intermediate object files,
+    you can use the &NoCache;
+    function to specify that the
+    object files should not be cached:

+       CacheDir('cache')
+       NoCache('hello.o')
+    </programlisting>
+
+    <para>
+
+    Then when you run &scons; after cleaning
+    the built targets,
+    it will recompile the object file locally
+    (since it doesn't exist in the shared cache directory),
+    but still realize that the shared cache directory
+    contains an up-to-date executable program

+
+    <para>
+
+    If you allow multiple builds to update the
+    shared cache directory simultaneously,
+    two builds that occur at the same time
+    can sometimes start "racing"
+    with one another to build the same files
+    in the same order.
+    If, for example,
+    you are linking multiple files into an executable program:
+
+    </para>
+
+    <programlisting>
+       Program('prog',
+               ['f1.c', 'f2.c', 'f3.c', 'f4.c', 'f5.c'])
+    </programlisting>
+
+    <para>
+
+    &SCons; will normally build the input object files
+    on which the program depends in their normal, sorted order:
+
+    </para>
+
+    <screen>
+      % <userinput>scons -Q</userinput>
+      cc -o f1.o -c f1.c
+      cc -o f2.o -c f2.c
+      cc -o f3.o -c f3.c
+      cc -o f4.o -c f4.c
+      cc -o f5.o -c f5.c
+      cc -o prog f1.o f2.o f3.o f4.o f5.o
+    </screen>
+
+    <para>
+
+    But if two such builds take place simultaneously,
+    they may each look in the cache at nearly the same
+    time and both decide that <filename>f1.o</filename>
+    must be rebuilt and pushed into the shared cache directory,
+    then both decide that <filename>f2.o</filename>
+    must be rebuilt (and pushed into the shared cache directory),
+    then both decide that <filename>f3.o</filename>
+    must be rebuilt...
+    This won't cause any actual build problems--both
+    builds will succeed,
+    generate correct output files,
+    and populate the cache--but
+    it does represent wasted effort.
+
+    </para>
+
+    <para>
+
+    To alleviate such contention for the cache,
+    you can use the <literal>--random</literal> command-line option
+    to tell &SCons; to build dependencies
+    in a random order:
+
+    </para>

+    </scons_output>
+
+    We captured it directly here to guarantee a "random" order,

+    to return things in the original sorted order.

+    </screen>
+
+    <para>
+
+    Multiple builds using the <literal>--random</literal> option
+    will usually build their dependencies in different,
+    random orders,
+    which minimizes the chances for a lot of
+    contention for same-named files
+    in the shared cache directory.
+    Multiple simultaneous builds might still race to try to build

+    but long sequences of inefficient contention
+    should be rare.

+    Note, of course,

+
+    How &SCons; handles dependencies can also be affected
+    by the &AlwaysBuild; method.
+    When a file is passed to the &AlwaysBuild; method,
+    like so:
+
+    </para>
+
+    <programlisting>
+      hello = Program('hello.c')
+      AlwaysBuild(hello)
+    </programlisting>
+
+    <para>
+
+    Then the specified target file (&hello; in our example)
+    will always be considered out-of-date and
+    rebuilt whenever that target file is evaluated
+    while walking the dependency graph:
+
+    </para>
+
+    <screen>
+      % <userinput>scons -Q</userinput>
+      cc -o hello.o -c hello.c

+
+    The &AlwaysBuild; function has a somewhat misleading name,
+    because it does not actually mean the target file will

+    Instead, it means that the target will, in fact,
+    be rebuilt whenever the target file is encountered
+    while evaluating the targets specified on
+    the command line (and their dependencies).
+    So specifying some other target on the command line,
+    a target that does <emphasis>not</emphasis>
+    itself depend on the &AlwaysBuild; target,
+    will still be rebuilt only if it's out-of-date

+
+    There may be additional files that you want removed
+    when the <literal>-c</literal> option is used,
+    but which &SCons; doesn't know about
+    because they're not normal target files.
+    For example, perhaps a command you invoke
+    creates a log file as
+    part of building the target file you want.
+    You would like the log file cleaned,
+    but you don't want to have to teach
+    SCons that the command
+    "builds" two files.
+
+    </para>
+
+    <para>
+
+    You can use the &Clean; function to arrange for additional files
+    to be removed when the <literal>-c</literal> option is used.
+    Notice, however, that the &Clean; function takes two arguments,
+    and the <emphasis>second</emphasis> argument
+    is the name of the additional file you want cleaned
+    (<filename>foo.log</filename> in this example):
+
+    </para>
+
+    <programlisting>
+        t = Command('foo.out', 'foo.in', 'build -o $TARGET $SOURCE')
+        Clean(t, 'foo.log')
+    </programlisting>
+
+    <para>
+
+    The first argument is the target with which you want
+    the cleaning of this additional file associated.
+    In the above example,
+    we've used the return value from the
+    &Command; function,
+    which represents the
+    <filename>foo.out</filename>
+    target.
+    Now whenever the
+    <filename>foo.out</filename> target is cleaned
+    by the <literal>-c</literal> option,
+    the <filename>foo.log</filename> file
+    will be removed as well:

+  <title>What Dependencies Does &SCons; Know About?  the &tree; Option</title>
+
+    <para>
+
+    Sometimes the best way to try to figure out what
+    &SCons; is doing is simply to take a look at the
+    dependency graph that it constructs
+    based on your &SConscript; files.
+    The <literal>--tree</literal> option
+    will display all or part of the
+    &SCons; dependency graph in an
+    "ASCII art" graphical format
+    that shows the dependency hierarchy.
+
+    </para>
+
+    <para>
+
+    For example, given the following input &SConstruct; file:
+
+    </para>
+
+    <scons_example name="tree1">
+      <file name="SConstruct" printme="1">
+         env = Environment(CPPPATH = ['.'])
+         env.Program('prog', ['f1.c', 'f2.c', 'f3.c'])
+      </file>
+      <file name="f1.c">
+      #include "inc.h"
+      </file>
+      <file name="f2.c">
+      #include "inc.h"
+      </file>
+      <file name="f3.c">
+      #include "inc.h"
+      </file>
+      <file name="inc.h">
+      inc.h
+      </file>
+    </scons_example>
+
+    <para>
+
+    Running &SCons; with the <literal>--tree=all</literal>
+    option yields:
+
+    </para>
+
+    <scons_output example="tree1">
+      <scons_output_command>scons -Q --tree=all</scons_output_command>
+    </scons_output>
+
+    <para>
+
+    The tree will also be printed when the
+    <literal>-n</literal> (no execute) option is used,
+    which allows you to examine the dependency graph
+    for a configuration without actually
+    rebuilding anything in the tree.
+
+    </para>
+
+    <para>
+
+    The <literaL>--tree</literal> option only prints
+    the dependency graph for the specified targets
+    (or the default target(s) if none are specified on the command line).
+    So if you specify a target like <filename>f2.o</filename>
+    on the command line,
+    the <literaL>--tree</literal> option will only
+    print the dependency graph for that file:
+
+    </para>
+
+    <scons_output example="tree1">
+      <scons_output_command>scons -Q --tree=all f2.o</scons_output_command>
+    </scons_output>
+
+    <para>
+
+    This is, of course, useful for
+    restricting the output from a very large
+    build configuration to just a
+    portion in which you're interested.
+    Multiple targets are fine,
+    in which case a tree will be printed
+    for each specified target:
+
+    </para>
+
+    <scons_output example="tree1">
+      <scons_output_command>scons -Q --tree=all f1.o f3.o</scons_output_command>
+    </scons_output>
+
+    <para>
+
+    The <literal>status</literal> argument may be used
+    to tell &SCons; to print status information about
+    each file in the dependency graph:
+
+    </para>
+
+    <scons_output example="tree1">
+      <scons_output_command>scons -Q --tree=status</scons_output_command>
+    </scons_output>
+
+    <para>
+
+    Note that <literal>--tree=all,status</literal> is equivalent;
+    the <literal>all</literal>
+    is assumed if only <literal>status</literal> is present.
+    As an alternative to <literal>all</literal>,
+    you can specify <literal>--tree=derived</literal>
+    to have &SCons; only print derived targets
+    in the tree output,
+    skipping source files
+    (like <filename>.c</filename> and <filename>.h</filename> files):
+
+    </para>
+
+    <scons_output example="tree1">
+      <scons_output_command>scons -Q --tree=derived</scons_output_command>
+    </scons_output>
+
+    <para>
+
+    You can use the <literal>status</literal>
+    modifier with <literal>derived</literal> as well:
+
+    </para>
+
+    <scons_output example="tree1">
+      <scons_output_command>scons -Q --tree=derived,status</scons_output_command>
+    </scons_output>
+
+    <para>
+
+    Note that the order of the <literal>--tree=</literal>
+    arguments doesn't matter;
+    <literal>--tree=status,derived</literal> is
+    completely equivalent.
+
+    </para>
+
+    <para>
+
+    The default behavior of the <literal>--tree</literal> option
+    is to repeat all of the dependencies each time the library dependency
+    (or any other dependency file) is encountered in the tree.
+    If certain target files share other target files,
+    such as two programs that use the same library:
+
+    </para>
+
+    <scons_example name="tree2">

+
+    <para>
+
+    In a large configuration with many internal libraries
+    and include files,
+    this can very quickly lead to huge output trees.
+    To help make this more manageable,
+    a <literal>prune</literal> modifier may
+    be added to the option list,
+    in which case &SCons;
+    will print the name of a target that has
+    already been visited during the tree-printing
+    in <literal>[square brackets]</literal>
+    as an indication that the dependencies
+    of the target file may be found
+    by looking farther up the tree:

+
+    <para>
+
+    Like the <literal>status</literal> keyword,
+    the <literal>prune</literal> argument by itself
+    is equivalent to <literal>--tree=all,prune</literal>.

+

+
+    <para>
+
+    In general, &SCons; tries to keep its error
+    messages short and informative.
+    That means we usually try to avoid showing
+    the stack traces that are familiar
+    to experienced Python programmers,
+    since they usually contain much more
+    information than is useful to most people.
+
+    </para>
+
+    <para>
+
+    For example, the following &SConstruct file:
+
+    </para>
+
+    <scons_example name="stacktrace">
+      <file name="SConstruct" printme="1">
+         Program('prog.c')

+      <scons_output_command>scons -Q</scons_output_command>
+    </scons_output>
+
+    <para>
+
+    In this case,
+    the error is pretty obvious.
+    But if it weren't,
+    and you wanted to try to get more information
+    about the error,
+    the &debug-stacktrace; option
+    would show you exactly where in the &SCons; source code

+

+    Not everyone has the necessary time or

+
+    The internal &SCons; subsystem that handles walking
+    the dependency graph
+    and controls the decision-making about what to rebuild
+    is the <literal>Taskmaster</literal>.
+    &SCons; supports a <literal>--taskmastertrace</literal>
+    option that tells the Taskmaster to print
+    information about the children (dependencies)
+    of the various Nodes on its walk down the graph,
+    which specific dependent Nodes are being evaluated,
+    and in what order.
+
+    </para>
+
+    <para>
+
+    The <literal>--taskmastertrace</literal> option
+    takes as an argument the name of a file in
+    which to put the trace output,
+    with <filename>-</filename> (a single hyphen)
+    indicating that the trace messages
+    should be printed to the standard output:

+
+    The <literal>--taskmastertrace</literal> option

+    it knows about for each Node,
+    and the order in which those dependencies are evaluated.
+    This can be useful as an alternate way to determine
+    whether or not your &SCons; configuration,

+    has actually identified all the correct dependencies
+    you want it to.

+  <title>What Dependencies Does &SCons; Know About?  the &tree; Option</title>
+
+    <para>
+
+    Sometimes the best way to try to figure out what
+    &SCons; is doing is simply to take a look at the
+    dependency graph that it constructs
+    based on your &SConscript; files.
+    The <literal>--tree</literal> option
+    will display all or part of the
+    &SCons; dependency graph in an
+    "ASCII art" graphical format
+    that shows the dependency hierarchy.
+
+    </para>
+
+    <para>
+
+    For example, given the following input &SConstruct; file:
+
+    </para>
+
+    <programlisting>
+         env = Environment(CPPPATH = ['.'])
+         env.Program('prog', ['f1.c', 'f2.c', 'f3.c'])
+    </programlisting>
+
+    <para>
+
+    Running &SCons; with the <literal>--tree=all</literal>
+    option yields:
+
+    </para>

+            +-inc.h
+    </screen>
+
+    <para>
+
+    The tree will also be printed when the
+    <literal>-n</literal> (no execute) option is used,
+    which allows you to examine the dependency graph
+    for a configuration without actually
+    rebuilding anything in the tree.
+
+    </para>
+
+    <para>
+
+    The <literal>--tree</literal> option only prints
+    the dependency graph for the specified targets
+    (or the default target(s) if none are specified on the command line).
+    So if you specify a target like <filename>f2.o</filename>
+    on the command line,
+    the <literal>--tree</literal> option will only
+    print the dependency graph for that file:
+
+    </para>
+
+    <screen>
+      % <userinput>scons -Q --tree=all f2.o</userinput>

+        +-f2.c
+        +-inc.h
+    </screen>
+
+    <para>
+
+    This is, of course, useful for
+    restricting the output from a very large
+    build configuration to just a
+    portion in which you're interested.
+    Multiple targets are fine,
+    in which case a tree will be printed
+    for each specified target:

+    </para>

+    completely equivalent.
+
+    </para>
+
+    <para>
+
+    The default behavior of the <literal>--tree</literal> option
+    is to repeat all of the dependencies each time the library dependency
+    (or any other dependency file) is encountered in the tree.
+    If certain target files share other target files,
+    such as two programs that use the same library:

+
+    <programlisting>
+         env = Environment(CPPPATH = ['.'],

+  <title>Where is &SCons; Blowing Up?  the &debug-stacktrace; Option</title>
+
+    <para>
+
+    In general, &SCons; tries to keep its error
+    messages short and informative.
+    That means we usually try to avoid showing
+    the stack traces that are familiar
+    to experienced Python programmers,
+    since they usually contain much more
+    information than is useful to most people.
+
+    </para>
+
+    <para>
+
+    For example, the following &SConstruct; file:
+
+    </para>
+
+    <programlisting>
+         Program('prog.c')
+    </programlisting>
+
+    <para>
+
+    Generates the following error if the
+    <filename>prog.c</filename> file
+    does not exist:
+
+    </para>
+
+    <screen>
+      % <userinput>scons -Q</userinput>
+      scons: *** Source `prog.c' not found, needed by target `prog.o'.  Stop.
+    </screen>
+
+    <para>
+
+    In this case,
+    the error is pretty obvious.
+    But if it weren't,
+    and you wanted to try to get more information
+    about the error,
+    the &debug-stacktrace; option
+    would show you exactly where in the &SCons; source code
+    the problem occurs:
+
+    </para>
+
+    <screen>
+      % <userinput>scons -Q --debug=stacktrace</userinput>
+      scons: *** Source `prog.c' not found, needed by target `prog.o'.  Stop.

+    </screen>
+
+    <para>
+
+    Of course, if you do need to dive into the &SCons; source code,
+    we'd like to know if, or how,
+    the error messages or troubleshooting options
+    could have been improved to avoid that.
+    Not everyone has the necessary time or
+    Python skill to dive into the source code,
+    and we'd like to improve &SCons;
+    for those people as well...

+  <title>How is &SCons; Making Its Decisions?  the &taskmastertrace; Option</title>
+
+    <para>
+
+    The internal &SCons; subsystem that handles walking
+    the dependency graph
+    and controls the decision-making about what to rebuild
+    is the <literal>Taskmaster</literal>.
+    &SCons; supports a <literal>--taskmastertrace</literal>
+    option that tells the Taskmaster to print
+    information about the children (dependencies)
+    of the various Nodes on its walk down the graph,
+    which specific dependent Nodes are being evaluated,
+    and in what order.
+
+    </para>
+
+    <para>
+
+    The <literal>--taskmastertrace</literal> option
+    takes as an argument the name of a file in
+    which to put the trace output,
+    with <filename>-</filename> (a single hyphen)
+    indicating that the trace messages
+    should be printed to the standard output:
+
+    </para>
+
+    <programlisting>
+      env = Environment(CPPPATH = ['.'])
+      env.Program('prog.c')
+    </programlisting>

+    <screen>

+      Taskmaster: 'prog.o': children:
+          ['inc.h', 'prog.c']
+          evaluating prog.o
+      cc -o prog.o -c -I. prog.c
+      Taskmaster: 'prog': children:
+          ['prog.o']
+          evaluating prog
+      cc -o prog prog.o
+      Taskmaster: 'prog': already handled (executed)
+    </screen>
+
+    <para>
+
+    The <literal>--taskmastertrace</literal> option
+    doesn't provide information about the actual
+    calculations involved in deciding if a file is up-to-date,
+    but it does show all of the dependencies
+    it knows about for each Node,
+    and the order in which those dependencies are evaluated.
+    This can be useful as an alternate way to determine
+    whether or not your &SCons; configuration,
+    or the implicit dependency scan,
+    has actually identified all the correct dependencies
+    you want it to.

+
+  NOTE:  This is (Yet) a(nother) pre-release of 0.97 for testing purposes.
+
+  From Joe Bloggs:
+
+  - Man page fix:  remove cut-and-paste sentence in NoCache() description.
+
+  From Dmitry Grigorenko and Gary Oberbrunner:
+
+  - Use the Intel C++ compiler, not $CC, to link C++ source.
+
+  From Helmut Grohne:
+
+  - Fix the man page example of propagating a user's external environment.
+
+  From Steven Knight:
+
+  - Back out (most of) the Windows registry installer patch, which
+    seems to not work on some versions of Windows.
+
+  - Don't treat Java ".class" attributes as defining an inner class.
+
+  - Fix detecting an erroneous Java anonymous class when the first
+    non-skipped token after a "new" keyword is a closing brace.
+
+  - Fix a regression when a CPPDEFINES list contains a tuple, the second
+    item of which (the option value) is a construction variable expansion
+    (e.g. $VALUE) and the value of the variable isn't a string.
+
+  - Improve the error message if an IOError (like trying to read a
+    directory as a file) occurs while deciding if a node is up-to-date.
+
+  - Fix "maximum recursion" / "unhashable type" errors in $CPPPATH
+    PathList expansion if a subsidiary expansion yields a stringable,
+    non-Node object.
+
+  - Generate API documentation from the docstrings (using epydoc).
+
+  - Fix use of --debug=presub with Actions for out-of-the-box Builders.

+
+  - Fix a "builders_used" AttributeError that real-world Qt initialization
+    triggered in the refactored suffix handling for Builders.
+
+  - Make the reported --debug=time timings meaningful when used with -j.
+    Better documentation of what the times mean.
+
+  - User Guide updates: --random, AlwaysBuild(), --tree=,
+    --debug=findlibs, --debug=presub, --debug=stacktrace,
+    --taskmastertrace.
+
+  - Document (in both man page and User's Guide) that --implicit-cache
+    ignores changes in $CPPPATH, $LIBPATH, etc.
+
+  From Jean-Baptiste Lab:
+
+  - Remove hard-coded dependency on Python 2.2 from Debian packaging files.
+

+    .bib file.
+
+  From Joel B. Mohler:
+
+  - Make additional TeX auxiliary files (.toc, .idx and .bbl files)
+    Precious so their removal doesn't affect whether the necessary
+    sections are included in output PDF or PostScript files.
+
+  From Gary Oberbrunner:
+
+  - Fix the ability to import modules in the site_scons directory from
+    a subdirectory.

   From Anonymous:
 
-  - Allow arbitrary white space after a SWIG %module declaration.
-
-  From Paul:
-
-  - When compiling resources under MinGW, make sure there's a space 
-    between the --include-dir option and its argument.
-
-  From Jay Kint:
-
-  - Alleviate long command line issues on Windows by executing command
-    lines directly via os.spawnv() if the command line doesn't need
-    shell interpretation (has no pipes, redirection, etc.).
-
-  From Walter Franzini:
-
-  - Exclude additional Debian packaging files from the copyright check.
-
-  From Fawad Halim:
-
-  - Handle the conflict between the impending Python 2.6 'as' keyword
-    and our Tool/as.py module name.
-
-  From Steven Knight:
-
-  - Speed up the Node.FS.Dir.rel_path() method used to generate path names
-    that get put into the .sconsign* file(s).
-
-  - Optimize Node.FS.Base.get_suffix() by computing the suffix once, up
-    front, when we set the Node's name.  (Duh...)
-
-  - Reduce the Memoizer's responsibilities to simply counting hits and
-    misses when the --debug=memoizer option is used, not to actually
-    handling the key calculation and memoization itself.  This speeds
-    up some configurations significantly, and should cause no functional
-    differences.
-
-  - Add a new scons-time script with subcommands for generating
-    consistent timing output from SCons configurations, extracting
-    various information from those timings, and displaying them in
-    different formats.
-
-  - Reduce some unnecessary stat() calls from on-disk entry type checks.
-
-  - Fix SideEffect() when used with -j, which was badly broken in 0.96.93.
-
-  - Propagate TypeError exceptions when evaluating construction variable
-    expansions up the stack, so users can see what's going on.
-
-  - When disambiguating a Node.FS.Entry into a Dir or File, don't look
-    in the on-disk source directory until we've confirmed there's no
-    on-disk entry locally and there *is* one in the srcdir.  This avoids
-    creating a phantom Node that can interfere with dependencies on
-    directory contents.
-
-  - Add an AllowSubstExceptions() function that gives the SConscript
-    files control over what exceptions cause a string to expand to ''
-    vs. terminating processing with an error.
-
-  - Allow the f90.py and f95.py Tool modules to compile earlier source
-    source files of earlier Fortran version.
-
-  - Fix storing signatures of files retrieved from CacheDir() so they're
-    correctly identified as up-to-date next invocation.
-
-  - Make sure lists of computed source suffixes cached by Builder objects
-    don't persist across changes to the list of source Builders (so the
-    addition of suffixes like .ui by the qt.py Tool module take effect).
-
-  - Enhance the bootstrap.py script to allow it to be used to execute
-    SCons more easily from a checked-out source tree.
-
-  From Ben Leslie:
-
-  - Fix post-Memoizer value caching misspellings in Node.FS._doLookup().
-
-  From Rob Managan, Dmitry Mikhin and Joel B. Mohler:
-
-  - Handle TeX/LaTeX files in subdirectories by changing directory
-    before invoking TeX/LaTeX.
-
-  - Scan LaTeX files for \bibliography lines.
-
-  - Support multiple file names in a "\bibliography{file1,file2}" string.
-
-  - Handle TeX warnings about undefined citations.
-
-  - Support re-running LaTeX if necessary due to a Table of Contents.
-
-  From Dmitry Mikhin:
-
-  - Return LaTeX if "Rerun to get citations correct" shows up on the next
-    line after the "Warning:" string.
-
-  From Gary Oberbrunner:
-
-  - Add #include lines to fix portability issues in two tests.
-
-  - Eliminate some unnecessary os.path.normpath() calls.
-
-  - Add a $CFLAGS variable for C-specific options, leaving $CCFLAGS
-    for options common to C and C++.
-
-  From Tom Parker:
-
-  - Have the error message print the missing file that Qt can't find.
-
-  From John Pye:
-
-  - Fix env.MergeFlags() appending to construction variable value of None.
-
-  From Steve Robbins:
-
-  - Fix the "sconsign" script when the .sconsign.dblite file is explicitly
-    specified on the command line (and not intuited from the old way of
-    calling it with just ".sconsign").
-
-  From Jose Pablo Ezequiel "Pupeno" Fernandez Silva:
-
-  - Give the 'lex' tool knowledge of the additional target files produced
-    by the flex "--header-file=" and "--tables-file=" options.
-
-  - Give the 'yacc' tool knowledge of the additional target files produced
-    by the bison "-g", "--defines=" and "--graph=" options.
-
-  - Generate intermediate files with Objective C file suffixes (.m) when
-    the lex and yacc source files have appropriate suffixes (.lm and .ym).
-
-  From Sohail Somain:
-
-  - Have the mslink.py Tool only look for a 'link' executable on Windows
-    systems.
-
-  From Vaclav Smilauer:
-
-  - Add support for a "srcdir" keyword argument when calling a Builder,
-    which will add a srcdir prefix to all non-relative string sources.
-
-  From Jonathan Ultis:
-
-  - Allow Options converters to take the construction environment as
-    an optional argument.
