How do I export to pages, mac program?

Does anybody knows how to export to Pages, the writing program for Mac? Is it possible?

See §23.3.2 (pg. 293) of the User Manual PDF, “Special Note on Pages”. It has instructions on what you need to do based on what you’ve got. For simple material, you can get by with RTF if you do not demand much, but if you have a complex document (footnotes, images, etc) then you’ll need to read this section for details on what to do.
