Here is the full source code (141 MB) and source code without documentation (33 MB) in zip files. If you would like to browse before you download, here is the HTML documentation.
The template libraries are in the packages directory. For the full source code version, you can make the documentation by running make in the doxygen directory. This will build documentation in the doc directory. Open the file stlib/doc/html/index.html. There are example programs in the examples directory and unit test code in the test directory.
