Builders
LyxBuilder: Convert .lyx files to .tex. And teach PDF to understand .lyx files.
ReplacementBuilder: for when you need to take a *.in file and replace some variables in it, such as pkg-config .pc files or DBus .service files
UsingCodeGenerators: how to build an application and then use that application to generate other files
PythonExtensions: how to build python extension modules using SCons Swig & Boost
PyrexPythonExtensions: how to build pyrex python extension modules using SCons
BuildNumberProcessing: you have a build number or version number that needs to be included in the link
UsingCompilerBuilt asks about building a compiler/tool which is then used to build the application.
NasmBuilder: how to compile nasm source files
RpcBuilder: how to compile RPC protocol sources
CorbaBuilder: Builder for orbix corba idl generated C++ files.
CorbaTaoBuilder: Builder for tao corba idl generated C++ files.
AntlrBuilder: Builder for antlr to create targets that Scons can use
RunningConfigureAndMake: how to use SCons to run configure and make, as part of migrating from Makefiles
AccumulateBuilder: builder which "collects" files and/or directories for easy tarring/zipping for distribution
UicImageEmbedder: builder which generates an image collection by embedding image files into a c++ sourcefile
SubstInFileBuilder: provides TOOL_SUBST, which substitutes values from a dictionary into a file. Can be used for autotools-like configure substitution or other purposes.
SubstInFileBuilder2: provides a slightly different implementation of SubstInFile that substitutes values from the environment into a file.
GenericSubstBuilder: Provides a powerful generic substitution mechanism and two helpers for regular files and headers.
DistTarBuilder: builds a tar file with an internal directory structure
DoxygenBuilder: generates doxygen docs automatically scanning for dependencies
CsharpBuilder: a builder to support C# using Mono, mcs, etc.
SwigBuilder: extra stuff about building SWIG beyond what's currently built-in.
NsisBuilder: see NsisSconsTool
EiffelStudioTool: Builder tool for the Eiffel programming language (EiffelStudio).
GchBuilder: Builder for gcc's precompiled headers
EnvValue: A value node which substitutes variables from the environment
CombineBuilder: Small Builder to include several c/c++ source files into one file
ArchiveBuilder: Builder to make archive (tar.gz, tar.bz2 or zip) in a simple way
GhcBuilder: Builder for the Haskell programming language.
CxxTestBuilder: Integrate CxxTest unit testing framework into scons, together with a 'scons check' target. (make check clone from autotools)
ReStructuredTextBuilder: produces HTML or LaTeX output from reStructuredText input
CheetahBuilder: compiles and fills Cheetah templates
SconsDotNet - using SCons to build CoctaThorpe and VbDotNet
InstallFiles - Recursively scan the source for files to install according to glob and exclude patterns
ProtocBuilder - Generates Protocol Buffers target files from .proto source.
PyuicBuilder - Generates PyQt Python files from QtDesigner .ui source.
MsvcIncrementalLinking - Replaces the Program and SharedLibrary builders to support Microsoft Visual C++ incremental linking.
StaticPicLibrary - a builder like StaticLibrary but aiming to place position independant code (pic) in the library built
Download- & UnpackBuilder - two correspondent builders, that can download and unpack a file (eg tar.gz / tar.bz2), usefull for installing libraries to a project
Tools for specific librairies
Qt4Tool: David García Garzón has been working on a Qt4 tool with much success
CheckBoostVersion: Boost does not provide pkg-config file so we need to check its version by other means
