PDFTools is a set of Perl scripts written for the purpose of
low-level user actions.
Currently, several commands are available:
pdfextract: extract some pages from a PDF file
pdfmerge: merge several PDF files
pdfpagecount: return the number of pages inside a PDF file
pdfsplit: split one or more PDF files to a bunch of one-page PDF
files
The documentation is available as POD inside of each script.
