[NTG-context] ctxtools.rb (was Re: Context 2006.08.08 released )

Hans,

The latest ctxtools.rb has:

        def locatedlocaltree
            tree = `kpsewhich --expand-path $TEXMFLOCAL`.chomp rescue
            nil
            unless tree && FileTest.directory?(tree) then
                tree = `kpsewhich --expand-path $TEXMF`.chomp rescue
            nil
            end
            return tree
        end

I know the Windows/Unix quoting isn't sorted out, but another problem
is with --expand-path.  If the
  
  kpsewhich --expand-path $TEXMF

line would get run here (with '$TEXMF'), it would produce

/home/sanjoy/.texmf-config:/home/sanjoy/.texmf-var:/home/sanjoy/texmf:/etc/texmf:/var/lib/texmf:/usr/local/share/texmf:/usr/share/texmf:/usr/share/texmf-tetex

which would eventually become the argument of an unhappy Dir.chdir().
Should localtedlocaltree() extract the first component before doing
'return tree'?
