You might want to look at pdftk.  On my Ubuntu GNU/Linux system,
it's installable with apt-get.  Here is a description:

#===================================================
Description: useful tool for manipulating PDF documents
 If PDF is electronic paper, then pdftk is an electronic stapler-remover,
 hole-punch, binder, secret-decoder-ring, and X-Ray-glasses. Pdftk is a simple
 tool for doing everyday things with PDF documents. Keep one in the top drawer
 of your desktop and use it to:
 * Merge PDF documents
 * Split PDF pages into a new document
 * Decrypt input as necessary (password required)
 * Encrypt output as desired
 * Fill PDF Forms with FDF Data and/or Flatten Forms
 * Apply a Background Watermark
 * Report PDF on metrics, including metadata and bookmarks
 * Update PDF Metadata
 * Attach Files to PDF Pages or the PDF Document
 * Unpack PDF Attachments
 * Burst a PDF document into single pages
 * Uncompress and re-compress page streams
 * Repair corrupted PDF (where possible)
