The following information was provided by the package's contributor.
Name of contribution: attachfile Author's name: Scott Pakin Location on CTAN: /macros/latex/contrib/attachfile/ Summary description: Attach an arbitrary file to a PDF document License type: lppl
Announcement text given by the package's contributor: - ---------------------------------------------------------------------- Starting with PDF 1.3 (Adobe Acrobat 4.0), PDF files can contain file attachments -- arbitrary files that a reader can extract, just like attachments to an e-mail message. The attachfile package brings this functionality to pdfLaTeX and provides some additional features not available in Acrobat, such as the ability to use arbitrary LaTeX code for the file icon -- including things like includegraphics, tabular, and math. Settings can be made either globally or on a per-attachment basis. attachfile makes it easy to attach files and customize their appearance in the enclosing document. - ----------------------------------------------------------------------
