NAME
ctags - Generate tag files for source code

SYNOPSIS
ctags [options] [file(s)]

etags [options] [file(s)]

DESCRIPTION
The ctags and etags programs (hereinafter collectively referred to as
ctags, except where distinguished) generate an index (or "tag") file
for a variety of language objects found in file(s). This tag file
allows these items to be quickly and easily located by a text editor or
other utility. A "tag" signifies a language object for which an index
entry is available (or, alternatively, the index entry created for that
object).

Alternatively, ctags can generate a cross reference file which lists,
in human readable form, information about the various source objects
found in a set of language files.

Tag index files are supported by numerous editors, which allow the user
to locate the object associated with a name appearing in a source file
and jump to the file and line which defines the name. Those known about
at the time of this release are:

Vi(1) and its derivatives (e.g. Elvis, Vim, Vile, Lemmy), CRiSP,
Emacs, FTE (Folding Text Editor), JED, jEdit, Mined, NEdit (Nirvana
Edit), TSE (The SemWare Editor), UltraEdit, WorkSpace, X2, Zeus

Ctags is capable of generating different kinds of tags for each of many
different languages. For a complete list of supported languages, the
names by which they are recognized, and the kinds of tags which are
generated for each, see the --list-languages and --list-kinds options.
