There is arrangement documentation in McLachlan/doc.  This could be added to.  I have always wanted Kranc to output documentation LaTeX files including the equations in tensorial form, but have not implemented this.  One problem was that there was no good way to automatically line-break the equations in LaTeX.  I think there are some hacks, but nothing reliable.  I would prefer the equation documentation to be automatically-generated, as otherwise it risks becoming out of date.
