  <p>BuildTool is a Java based build tool. In theory it is kind of like make without

    makes wrinkles.</p>
  <p>Why another build tool when there is already make, gnumake, nmake, jam, and 
    others? Because all of those tools have limitations that its original author 
    couldn't live with when developming software across multiple platforms. Make 
    like tools are inherently shell based. They evaluate a set of dependencies and 
    then execute commands not unlike what you would issue on a shell. This means 
    that you can easily extend these tools by using or writing any program for the 
    OS that you are working on. However, this also means that you limit yourself 
    to the OS, or at least the OS type such as Unix, that you are working on.</p>
  <p>Makefiles are inherently evil as well. Anybody who has worked on them for any 
    time has run into the dreaded tab problem. &quot;Is my command not executing 
    because I have a space in front of my tab!!!&quot; said the original author 
    of BuildTool way too many times. Tools like Jam took care of this to a great 
    degree, but still use yet another format to use and remember.</p>
  <p>BuildTool is different. Instead a model where it is extended with shell based 
    commands, it is extended using Java classes. Instead of writing shell commands, 
    the configuration files are XML based calling out a target tree where various 
    tasks get executed. Each task is run by an object which implments a particular 
    Task interface. </p>
  <p>Granted, this removes some of the expressive power that is inherent by being 
    able to construct a shell command such as `find . -name foo -exec rm {}` but 
    it gives you the ability to be cross platform. To work anywhere and everywhere.And 
    hey, if you really need to execute a shell command, BuildTool has an exec rule 
    that allows different commands to be executed based on the OS that it is executing 
    on. </p>
