echo 'test_all_pdfs.sh
Usage: Run from the trunk directory of a Skia tree to convert a folder of PDFs into PNGs.
Many threads will be run simultaneously using the "parallel" tool if that tool is
installed. "parallel" can be installed on linux using "sudo apt-get install parallel."
Requires that skdiff and pdfviewer have already been built.
Arguments:
folder Folder containing PDF files. The PNG results will be placed in "folder/new".
If folder contains a folder named "old", the PNGs in "folder/new" will be
compared to PNGs in "folder/old" with the same name, and the differences
will be stored in a "folder/d".'
