JamPlus

h1. Overview

JamPlus is a powerful code and data build system built on the code base of the original Perforce version of Jam, a software build tool similar to *make*.

JamPlus adds new features to Jam and integrates a number of patches from the Jamming mailing list and the Perforce Public Depot.

A sampling of the new features in the JamPlus distribution follows:

* *Multiple Passes:* The ability to run multiple internal passes, collecting unknown dependencies, and executing them in a future pass.

* *Network Cache:* Any to-be-built target can be retrieved from one or more shared network caches of prebuilt targets.

* *Command-line Dependencies:* When the 'command line' of a target (not necessarily the real command line) changes, the target is rebuilt.

* *Powerful New Variable Expansion:* Convert between slash types, expand literal text, include or exclude list components, recursive file globs, and more.

* *Dependency (Header) Cache:* When dependency information is scanned, it is cached for the next build, offering a huge performance boost.

* *Batch Compilation:* JamPlus is able to batch files to tools that support it, such as the Visual C++ compiler.

* *Workspace/Project Generator:* JamPlus can output project files for the Visual Studio IDE, Xcode, and CodeBlocks.

JamPlus 1.0 (currently a nightly build) has support for Visual C++ 200x/2010 and GCC/MinGW builds and works on Windows, Linux, and Mac OS X.
