+Custom Paper Size:
+ Paper size can be set manually in Milimeters, Inches or Points.
+ Use: pdfScale.sh -r 'custom <measurement> <width> <height>'
+ Ex:  pdfScale.sh -r 'custom mm 210 297'
+ Measurements can be: mm, inch, pts.
+ Custom paper definition MUST be quoted into a single parameter.
+ Actual size is applied in points (mms and inches are transformed).
