Shell frontend for the LaTeX pdfpages package for mingling PDFs. More information: <https://github.com/rrthomas/pdfjam>.

• Merge two (or more) PDFs:
  pdfjam path/to/file1.pdf path/to/file2.pdf --outfile path/to/output_file.pdf
• Merge the first page of each file together:
  pdfjam files... 1 --outfile path/to/output_file.pdf
• Merge subranges from two PDFs:
  pdfjam path/to/file1.pdf 3-5,1 path/to/file2.pdf 4-6 --outfile path/to/output_file.pdf
• Sign an A4 page (adjust delta to height for other formats) with a scanned signature by overlaying them:
  pdfjam path/to/file.pdf path/to/signature --fitpaper true --outfile path/to/signed.pdf --nup "1x2" --delta "0 -842pt"
• Arrange the pages from the input file into a fancy 2x2 grid:
  pdfjam path/to/file.pdf --nup 2x2 --suffix 4up --preamble '\usepackage{fancyhdr} \pagestyle{fancy}'
• Reverse the order of pages within each given file and concatenate them:
  pdfjam files... last-1 --suffix reversed
