Does RTC support formatting source before check-in or deliver?

Accepted answer

I'm not sure about RTC itself without writing some custom code, but if you're using the Eclipse client for Java development you can set up a variety of "save actions", including formatting source. Preferences > Java > Editor > Save Actions. Every developer would have to enable this setting though, and it doesn't apply to other types of source files.
