   5 NAME
   6        xref - build and maintain source cross-references
   7 
   8 SYNOPSIS
   9        xref [-cfp] [-m <makefile>] [-x cscope|ctags|etags[,...]] [<subtree>
  10        ...]
  11 
  12 DESCRIPTION
  13        xref is a simple tool for building and maintaining source cross-
  14        references for subtrees of a workspace.  By default, xref builds
  15        cscope-fast, ctags, and etags (if available; see NOTES) source cross-
  16        references for all of the eligible files underneath each named subtree,
  17        plus any additional eligible files reported by flg.flp(1ONBLD).  File
  18        eligibility is determined by pattern matching -- by default, files
  19        matching the following patterns are eligible:
  20 
  21             *.[Ccdshlxy] Makefile* *.il* *.cc llib-* *.xml *.dtd.* *.ndl

 118        invokes make(1) with the -e option, the value of any macros used by
 119        xref.mk can be overridden through environment variables.  This is
 120        chiefly useful for customizing the programs used to build the cross
 121        references; see EXAMPLES.

 123 SEE ALSO
 124        make(1), bringover(1ONBLD) flg.flp(1ONBLD)
 125 
 126 NOTES
 127        The etags utility is no longer bundled with the Sun Studio, which means
 128        it may not be available on all developer systems.  If xref cannot
 129        locate the etags utility and the -x option has not been specified, then
 130        xref will silently not build etags.
 131 
 132        The ETAGS environment variable can be used to specify an alternate path
 133        to the etags utility.  For instance, to use the one included with
 134        SUNWgnu-emacs, set ETAGS to /usr/gnu/bin/etags prior to invoking xref.
