PDF INTERLEAVING.

This script takes two PDF files as arguments and outputs the first in- terleaved with the second.

This may be useful if you have several two-sided documents to scan and a single-sided Automatic Document Feeder Scanner.

Just scan all odd pages to a file and all even ones to another. Then:

pdfinterleave.pl oddpages.pdf evenpages.pdf > fulldocument.pdf

Use:

-r If you need to reverse the evenpages file.
-l If you want to discard the last page of evenpages file.

Requisites:

Perl        - This is a perl program ;)
PDF::API2   - Perl extension to handle PDFs.

use $cpan PDF::API2 to install that.
