 # A simple script useful to rotate a series of scanned pdfs files and, after
 # that, concat them.
 # manage_scans.bash takes as input three arguments (one of which is optional):
 # - source: a path to the folder of source pdf files to manage;
 # - destination: a path to the folder where you will see a new pdf file and
 #   where new temp files will be put
 # - output (optional): the name of the file which will be created at the end
 #   of execution
