I only made a mechanism for generating referece tags. You need to write
a parser using the mechanism, that is, makeSimpleReferenceTag().It's very easy.

For example, here is an example which treats references of Scheme language.
(You need to install the CVS version of GLOBAL.)

$ gtags
$ global -x  current-line
current-line       37 scm/error.scm    (define current-line #f)         <= 
definitions
$ global -xr current-line
current-line       40 scm/error.scm      (set! current-line line))      <= 
references
current-line       43 scm/error.scm      (set! current-line #f))

Here is a patch to realize above.
