"""
Concatenate pages from pdf files into a single pdf file.
Page ranges refer to the previously-named file.
A file not followed by a page range means all the pages of the file.
PAGE RANGES are like Python slices.
{page_range_help}
EXAMPLES
pdfcat -o output.pdf head.pdf content.pdf :6 7: tail.pdf -1
Concatenate all of head.pdf, all but page seven of content.pdf,
and the last page of tail.pdf, producing output.pdf.
pdfcat chapter*.pdf >book.pdf
You can specify the output file by redirection.
pdfcat chapter?.pdf chapter10.pdf >book.pdf
In case you don't want chapter 10 before chapter 2.
