All Trinity programs use this library to provide basic functionality such as the configuration system, IPC, internationalization and locale support, site-independent access to the filesystem and a large number of other (but no less important) things.
All Trinity applications should link to the tdecore library. Also, using a TDEApplication derived class instead of TQApplication is almost mandatory if you expect your application to behave nicely within the Trinity environment.
If you are unsure where to start, have a look at the tutorials on the Trinity project site to get you going.
If you know what you are looking for, you should be able to find it in the class list or the modules list.
