I would like a TeXmacs equivalent of pdfpages, for including PDF sub-documents as exhibits in court documents. I'd like TeXmacs to keep track of page numbers and to have title pages with optional summaries for each labeled exhibit. I'd like exhibits to be either numbered or letter-labeled, and for the title page for each exhibit to appear in the table of contents and PDF bookmarks. I would also like to be able to add toc entries, bookmark entries, and labels for pagerefs for specific pages of those pdfpages documents.
