[texhax] notes at end of book

[Robin Fairbairns]

i've not investigated it in detail, but there's a relatively new
package called pagenote on ctan (note, it's singular, unlike
endnotes).  its usage may be rather clearer (i've had difficulty with
endnotes myself): if nothing else, pagenote's author has a reputation
for good documentation.

macros/latex/contrib/pagenote -- the doc is there as a .pdf file
