Scale and tile PS and PDF page to print on multiple pages.
Psdfposter can be used to create a large poster by building it from multple pages and/or printing it on large media. It expects as input a PS or a PDF file, printing on a single page. The output is again a PS or PDF file, maybe containing multiple pages together building the poster. The input page will be scaled to obtain the desired size.
Much like poster does for Postscript files, but working with PS and PDF. Since sometimes pspdfposter does not like your PS files. Indeed pspdfposter was inspired by poster.
Psdfposter is a bash script. It has a zenity GUI and need a good software to work, pspdftool that you can find at sourceforge.net (http://sourceforge.net/projects/pspdftool/)
For now it is only in Italian, has an ugly code, (I am not a real programmer, I am a teacher of physical education), it has not a guide, but it works well.
