Linux System - Table 12 > Packages - Table 9 > ctags

The ctags program generate an index (or \"tag\") file for C, C++, Eiffel,Fortran, and Java language objects found in files. 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, inhuman readable form, information about the various source objects found in a set of language files.
