I'm happy to announce pdfrecycle 0.05
pdfrecycle creates a PDF file by composing pages from other PDF files. It can add PDF bookmarks and metadata, scale, rotate and crop pages and put multiple logical pages onto each physical sheet.
pdfrecycle uses a simple text file format to define the layout and what pages to include. From this input file pdfrecycle creates a LaTeX file and then runs pdflatex to produced the PDF file.
With version 0.05 you can put pages of different input files on one output sheet and/or cut of parts of input pages.
