svn commit: r465414 - /incubator/adffaces/trunk/plugins/maven-faces-plugin/src/main/java/org/apache/myfaces/trinidadbuild/plugin/faces/GenerateFacesConfigMojo.java

[aw...@apache.org]

Author: awiner

New Revision: 465414

URL: http://svn.apache.org/viewvc?view=rev&rev=465414
Log:
Add support for a transformStylesheet property, which is the name of an XSLT stylesheet in src/main/conf that will be applied as the final step of faces-config.xml generation.  This can be used to implement any final fixup of the output.
