pdfname 
Description
The pdfname command-line program names a PDF file using the author, year of creation and title information extracted from the pdfinfo program.
Prerequisites
Installation
The program can installed with the following commands:
$ cabal update
$ cabal install pdfname
Usage
Just run pdfname on your PDF file.
How is the FileName Chosen?
Given the author, year of creation and title information extracted from the pdfinfo program (fields Author, CreationDate and Title, respectively) the name of the PDF file will be
author-year.title.pdf
where author and title are the strings obtained after making certain substitutions (e.g. remove whitespace, translate non-ASCCI characters and remove TeX/LaTeX specific information) to the information shown by the pdfinfo program.
Example. Let's suppose that running pdfinfo on the file foo.pdf shows the following (fictional and incomplete) information:
$ pdfinfo foo.pdf
Title: Introducction to the <TEX>$\lambda$</TEX>-Calculus
Author: Per Martin-Löf
CreationDate: Fri Apr 9 07:14:01 2010
Now, running pdfname on that file will create the new file
/tmp/martin-lof-2010.introduction-to-the-lambda-calculus.pdf
