According the Chandler project website.
Our goal is to serve the way people actually work, independently and together, particularly in small groups, a market segment we believe is undeserved. Our belief is that personal and collaborative information work is by nature iterative and that the existing binary Done/Not-Done, Read/Unread, Flagged/Unflagged paradigm in productivity software poorly accommodates the reality of how people work.
We are also committed to breaking down technological barriers that prevent effective collaboration. Chandler Desktop and Chandler Server are cross-platform and standards-based because we realize that collaboration can’t and shouldn’t be trapped within a single system. Chandler Server provides web access to shared information that makes it easy for collaborators to hook into Chandler work flows without having to download the Desktop application.

There is usually an equivalent ‘no’ flag. For example, -ftree-dce can be turned off by -fnotree-dce. Check the gcc docs for more flags.
