38 &SCons; is a software construction tool (build tool, or make tool)
39 implemented in Python, which uses Python scripts as "configuration
40 files" for software builds. Based on the design which won the
41 Software Carpentry build tool competition, &SCons; solves a number of
42 problems associated with other build tools, especially including the
43 classic and ubiquitous &Make; itself.
49 Distinctive features of &SCons; include: a modular design that
50 lends itself to being embedded in other applications; a global
51 view of all dependencies in the source tree; an improved model for
52 parallel (<option>-j</option>) builds; automatic scanning of files for
53 dependencies; use of MD5 signatures for deciding whether a file
54 is up-to-date; use of traditional file timestamps instead of
55 MD5 signatures available as an option;
56 use of Python functions or objects to build target files; easy user
63 This paper discusses the goals of the &SCons; project, gives an overview
64 of the design of &SCons; itself, describes the development process used,
65 and discusses future plans and directions for the tool.
