Soot is a Java optimization framework. It provides four intermediate representations for analyzing and transforming Java bytecode:

• Baf: a streamlined representation of bytecode which is simple to manipulate.
• Jimple: a typed 3-address intermediate representation suitable for optimization.
• Shimple: an SSA variation of Jimple.
• Grimp: an aggregated version of Jimple suitable for decompilation and code inspection.

See http://www.sable.mcgill.ca/soot/ for details.

We have some documentation on Soot in the wiki and also a large range of tutorials on Soot.

Nightly builds of soot can be obtained from nightly build. You might have to downloads the dependency jars as well.

Soot follows the git-flow convention. Releases and hotfixes are maintained in the master branch. Development happens in the develop branch. To catch the bleeding edge of Soot, check out the latter. You will also need the projects jasmin and heros. In case of any questions, please consult the Soot mailing list at: http://www.sable.mcgill.ca/mailman/listinfo/soot-list/
