To make it clear, the patch improves the performance of the *current* map file handling of pdfTeX. It saves me *much* time in comparison to the binary of TeXLive 7. But for *future* versions we should find an agreement about the behaviour of pdfTeX regarding map files, eg: * Map files: * Where can they specified? * config file (pdftex.cfg) * support of other config files * config files given on command line * map files given on command line * config files given by command * map files given by command * ... * When they are evaluated? * static, first use * dynamic changes possible? * Which order? * default, if no map file is given? * adding mapfiles * replacing mapfiles * order ... * ... * Map entries: * later entries are ignored with warning (current) * later entries replaces older ones silently * syntax ... * ... I hope I will find some time next days to give a suggestion for a specification. One aim can be to make the behaviour similar to dvips. Yours sincerely Heiko <oberdiek(a)uni-freiburg.de>

It's in (#2880). I've removed <Output the info object@> as it was superfluous.

Hi, I'd like to continue developement as there are at least two bugs that need fixing: - the patch regarding PDF:-specials - pdftex currently only looks at the filename to detect the filetype. That makes it impossible to include a pdf named other than .pdf Can we resume working in source.developement without an immediate distribution of intermediate versions via web2c et.al.?

Link to pdftex.exe on www.pdftex.org

Fabrice, www.pdftex.org currently has links to the binaries of pdf{e}TeX for most operating systems. I'm a bit confused about the size of win32/pdftex.exe and fear that most of pdftex is hidden in some dll. Is it even possible to get a new pdfTeX for win32 by downloading only some files and putting them into a TL7 installation? And which files would that be?
