special editor features

Several editors have specially written modes for cscope. Among these are: XEmacs, emacs, vim and nvi. Xemacs in particular has some significant features layered on top of the standard cscope features:

• An automatic, hierarchical, search path mechanism exists, for locating cscope index files. If a database isn't found in the current directory, the interface will automatically search parent directories for index files.
• In addition to your basic (normal) cscope setup, the XEmacs interface is also designed to support LARGE projects. Files which are indexed can be spread out over multiple directories, and these directories do NOT have to share a common root directory. Also, cscope index files can be shared amongst users. This is very useful for group software development.
• Multiple cscope index files can be searched. Unlike plain cscope, you're not limited to searching only one database.
• When searching multiple database (index) files, results can be returned from either the first database that contains matches, or all databases that contain matches. This is very useful when you have a local (partial) source tree, yet want to be able to search both your local tree and your project's full source tree.
• Cscope is integrated into the C, C++, and dired modes. Pull-down and pop-up menus exist, as well as normal key bindings.

For those of you who use emacs, there are even special cscope emacs modes that make it easier still.
