NAME
gtags - create tag files for global.
SYNOPSIS
gtags [-iIqvw][-f file][-n number][dbpath]
DESCRIPTION
Gtags recursively collect the source files under the current directory, pickup symbols and
write the cross-reference data into tag files (´GTAGS´, ´GRTAGS´, ´GSYMS´ and ´GPATH´).
You should execute this command at the root of the source tree.
C, C++, yacc, java, PHP and Assembly source files are supported. Files whose names end in
´.c´ or ´.h´ are assumed to be C source files. Files whose names end in ´.c++´ ´.cc´
´.cpp´ ´.cxx´ ´.hxx´ ´.hpp´ ´.C´ ´.H´ are assumed to be C++ source files. Files whose
names end in ´.y´ are assumed to be YACC source files. Files whose names end in ´.java´
are assumed to be Java source files. Files whose names end in ´.php´ ´.php3´ ´.phtml´ are
assumed to be PHP source files. Files whose names end in ´.s´ or ´.S´ are assumed to be
Assembly source files. Other files are assumed to be text files.
