BuddyPress.org

We are rebuilding our themes to accommodate the new BP structure and integrating our main theme with out buddypress theme… is there a way to create an if then statement so that we can choose to only show specific code when a buddypress centric page is served?

For example: If we only want certain css calls in the head to appear on buddypress pages (BP home page, group, blog, member, pages, etc.) or say we have a specific menu item or other block of code we only want to show on BP pages, how would we create the if then statement to make this happen?

Any feedback greatly appreciated!
