pdfdir
Joins a bunch of PDF files in a directory hierarchy into a single pdf.
Creates a bookmark to each file (bookmarks are the table of contents
found in the sidebar of most PDF readers).
If you arrange your PDF files in a hierarchy, like this:
book / 01-Introduction.pdf
book / 02-Engine
book / 02-Engine / 01-Coolant.pdf
book / 02-Engine / 02-Freeze Plugs.pdf
(the "01-", "02-" prefixes determine the order of the chapters in the
final book. They will not appear in the bookmarks.)
Then run:
$ pdfdir-join book
you will find the result in "book.pdf"
Too easy!
requires: Ghostscript, JPdfBookmarks

This package also includes some tools to help assemble the input files.
This will find corrupt PDFs:
$ pdfdir-verify book
It uses Ghostscript to carefully process every page of every PDF file.
This is awfully slow. You can specify --quick for a 10X speedup
at the risk of missing some obscure corruptions.
If you're having trouble with encrypted or corrupt PDFs, try using
pdfdir-copy to duplicate your entire directory structure. It takes
a while but, because it re-encodes each PDF, the result is sure to
be valid.
$ pdfdir-copy book /tmp/book-fixed
