=Multiple source patterns (beta)=

Many AMW examples use ATL matching transformations with multiple source patterns, i.e., ATL rules that match more than one element. This feature is not yet available for download in the official binary versions of ATL because it is under testing. 
However, a beta version is available for download in the AMW page. Follow the installation instructions below: 

== Installation from the sources: ==

Download the file [http://www.eclipse.org/gmt/amw/download/compiler_beta/ATLToASMCompiler.asm ATLToASMCompiler.asm] and copy it into "org.atl.eclipse.engine/src/org/atl/eclipse/engine/resources".

After copying the new compiler, be sure the ATL transformation was recompiled. 
To do that, just modify and save the .atl file.

== Installation from the binaries: ==

Download the [http://www.eclipse.org/gmt/amw/download/compiler_beta/org.atl.eclipse.engine_1.0.7.jar org.atl.eclipse.engine_1.0.7.jar] plugin and copy it into the "eclipse/plugins" folder. 
The binaries must have been compiled with the latest ATL sources.
