JamPlus

h1. Overview

JamPlus is a software build tool, similar to *make*.  It is built on Perforce's Jam 2.5 and contains necessary and useful patches from the Perforce Jamming mailing list and Perforce Public Depot.  JamPlus also has a number of new features above and beyond any published patches.

The JamPlus Jambase has support for Visual C++ builds only at this time.  Other compilers are forthcoming.

h1. Features

A sampling of the new features in the JamPlus distribution is below.  More detailed accounts can be found on the New Features page.

* All the power of the core Perforce Jam 2.5 software.

* *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.
