portlet.xml
liferay-portlet.xml
liferay-plugin-package.properties
liferay-look-and-feel.xml
Color schemes are defined in:
liferay-color-scheme.xml
portal-ext.properties
The JavaScript method that executes after each portlet on the page loads is:
AUI().ready(fn)
Liferay.Portlet.ready(fn)
Liferay.on(allPortletsReady', fn)
None of the above
