Hello, this is Yamaguchi.

I put the source code of GLOBAL version1.3 for FreeBSD 2.1R at

	http://ux01.so-net.or.jp/~shigio/freebsd/emain.html

GLOBAL is a command which find the locations of specified function
in C source files. This includes the patch for VI(nvi/nex 1.34) to use
global within the editor. 

NEW FEATURE in VERSION 1.3:
~~~~~~~~~~~~~~~~~~~~~~~~~~~
o Global search in not only a source tree but also library paths specified
  by environment variable GTAGSLIBPATH.

Example:
   % cd /develop/src/mh
   % gtags				<- make tag file
   % global mhl
   uip/mhlsbr.c				<- mhl() found in the source tree
   % global strlen			<- strlen() not found
   % cd /usr/src/lib
   % gtags				<- make library tag
   % cd /usr/src/sys
   % gtags				<- make system call tag
   % setenv GTAGSLIBPATH /usr/src/lib:/usr/src/sys
   % cd /develop/src/mh
   % global strlen
   ../../../usr/src/lib/libc/string/strlen.c	<- strlen() is found in library
   % global access
   ../../../usr/src/sys/kern/vfs_syscalls.c	<- access() is found in kernel

OTHER FEATURES:
~~~~~~~~~~~~~~~
o Global can find the locations of specified function very quickly.
o Global can locate not only function definitions but also function references.
o Global can treat a source tree containing subdirectories and you can get
  relative path of objects from anywhere within the tree.
o Global allow duplicate entries.
o Global can understand perl's regular expression.
o Global can be executed from vi's tag commands.(nvi/nex 1.34 only)

The new version of nvi/nex(1.61 and later) supports duplicate entries
in tags file. You can use patched ctags in this this package with the nvi/nex.

If you cannot get items, please send E-mail to me.

Please enjoy.
