@PageBox troubles

[Rodrigo Vanegas]

Why won't the following simple document work?

  @SysInclude { doc }
  @Document
    @PageBoxType { CurveBox }
  //
  @Text @Begin
  blah blah blah
  @End @Text

The error is simply this.

  3,3: symbol @PageBoxType unknown or misspelt
  2,1 fatal error: missing @Break symbol or option

It works fine if I instead make my own copy of include/doc and
uncomment the appropriate line there.  But I am lead to believe that
the above will work by the beginning of chapter 3 in the user's guide.
Any ideas?
