- Removed obsolete utils.sgml
- Added a ChangeLog entry for this replacement, which partially took
place days ago. This checkin formalizes the switch from SGML to
DocBook XML for this file.

include. You can't mix the two fragment inclusion mechanisms within
a single document because of the way it interacts with autoconf "build
in separate tree" mechanism. Either work separately, but they fail when
you try to use them together due to the way doctool chooses output
directories for its generated files.

effect is to move away from DocBook SGML and DJ Delorie's doctool and
toward pure DocBook XSL. (There remains just one use of doctool, and
we have plans for replacing it, too.) See ChangeLog for details.
