Here is the (just tested!) procedure to submit ConTeXt documents to arxiv.org and also provide source. Suppose that document.tex is the source file, and has fig.mp as the figure file that produces fig.1, etc. 1. Generate document.ps using texexec --dvi --nobackend document.tex dvips -Ppdf document.dvi -o document.ps /* the -o in case of stupid systems that send the output to lpr by default */ 2. Make a directory src/ with document.tex and fig.mp. Then make a .tgz file for uploading. It is produced from this file structure document.ps src/ fig.mp document.tex e.g. by tar -czvf arxiv.tgz document.ps src/ 3. arxiv.org will generate PDF from the PS using ghostscript, so make sure that ps2pdf on document.ps produces a working PDF. 4. If all is well, upload arxiv.tgz as your submission using the usual arxiv.org submission (or replacement) procedure. Ideally you'll do step 4 at least 15 minutes (ideally an hour) before the 4pm (US Eastern) weekday deadline, so that you get back the submission date and preprint number from arxiv, leaving time for step 5 5. Incorporate the preprint number (or URL) and submission date into your document and produce an arxiv stampline along the left. Then remake document.ps and arxiv.tgz in step 2, and replace the previous submission with the new arxiv.tgz. 6. Check that all is well. When the paper becomes official (8pm US Eastern time), users should get three choices for format: PS (what you provided), PDF (generated by arxiv.org from the PS), and 'Other formats', which will offer an option to download source. Of course, all of the remaking should be done by a Makefile. You can see http://www.arxiv.org/abs/0704.1854 for an example with a Makefile.
