Exuberant Ctags is a multilanguage reimplementation of the much-underused

ctags(1) program and is intended to be the mother of all ctags programs. It

generates indexes of source code definitions which are used by a number of

editors and tools. The motivation which drove the development of Exuberant

Ctags was the need for a ctags program which supported generation of tags

for all possible C language constructs (which no other ctags offers), and

because most were easily fooled by a number of preprocessor contructs.
