Apache Flex (Flex)
==================

    Apache Flex is an application framework for easily building Flash-based applications 
    for mobile devices, the browser and desktop.
    
    For detailed information about Apache Flex please visit 
    http://incubator.apache.org/flex/

    Apache Flex is a large project with many pieces.  The framework is implemented
    in Actionscript and the compiler is implemented in Java.

    Currently supported platforms include:

        Microsoft Windows
        Mac OS X
        Apple iOS
        Google Android
        RIM BlackBerry

    Apache Flex is the software evolution of the popular Adobe Flex SDK project.
    
    The community surrounding Flex is vast, diverse, distributed globally, and with all 
    levels of proficiency in software development. It is estimated that there are between 
    350,000 and 500,000 Flex developers worldwide. 

Getting the latest sources via Subversion
=========================================

    You can always checkout the latest source via subversion using the following
    command:

    svn co https://svn.apache.org/repos/asf/incubator/flex/trunk flex

Building Apache Flex
====================

    Apache Flex is a large project and depends on several external libraries which
    are downloaded as part of the build process.
    
    Before building Flex you must install:
    
        Java SDK 1.5.0_13 or greater
        Ant 1.7.0 or greater
        ant-contrib-1.0b2.jar in the lib directory of your ant installation
        on Windows you need to run from a shell like Cygwin or git bash
        
    The following environment variables must be set:
    
        JAVA_HOME
        ANT_HOME

    The PATH must include
    
        bin directory of Flex SDK
        bin directory of Ant
        bin directory of Java
    
    For testing, the Flash Player's mm.cfg file must have the following entries
    
        ErrorReportingEnable=1
        TraceOutputFileEnable=1
    
    and a FlashPlayerTrust file must allow local SWFs to access local files.

    With you have all the prerequisites in place, use

        cd <flex.dir>
        ant main        (or just ant since the default target is main)
    
    to download the thirdparty dependencies and build all the sources.  Since the thirdparty
    dependencies take a little while to download and they don't change very often, they are not
    cleaned with the regular clean target.  They thirdparty dependencies be found in the "in" 
    directory.
    
    To clean the build, of everything other than the downloaded third-party dependencies use
    
        ant clean 
    
    To clean the build, of everything, including the downloaded third-party dependencies use
        
        ant super-clean (which is just thirdparty-clean followed by clean)
        
    To generate a source distro and a binary distro use
        
        ant release
    
    The output distros can be found in the "out" subdirectory.
    
    To download the dependencies use
    
        ant thirdparty-downloads
            
    To clean the build ofjust the downloaded third-party dependencies use
    
        ant thirdparty-clean
        
    To get a brief listing of all the targets type
    
        ant help
