"""Return a PDF compiled by concatenating multiple documents.
Returns a PDF compiled by concatenating multiple documents. The documents
can be from a single DocType or multiple DocTypes
Note: The design may seem a little weird, but it exists to ensure backward compatibility.
The correct way to use this function is to pass a dict to doctype as described below
NEW FUNCTIONALITY
=================
Parameters:
doctype (dict):
key (string): DocType name
value (list): of strings of doc names which need to be concatenated and printed
name (string):
name of the pdf which is generated
format:
Print Format to be used
Returns:
PDF: A PDF generated by the concatenation of the mentioned input docs
OLD FUNCTIONALITY - soon to be deprecated
=========================================
Parameters:
doctype (string):
name of the DocType to which the docs belong which need to be printed
name (string or list):
If string the name of the doc which needs to be printed
If list the list of strings of doc names which needs to be printed
format:
Print Format to be used
Returns:
Publishes a link to the PDF to the given task ID
