'''\
Generate a document from a document template.
The document will be generated by inserting values into the
format string specified when the document template was
created. Values are inserted using standard python named
string formats.
The optional argument 'client' is used to specify a object
containing values to be looked up. Values will be looked up
using getattr, so inheritence of values is supported. Note
that names beginning with '_' will not be looked up from the
client.
The optional argument, 'mapping' is used to specify a mapping
object containing values to be inserted.
Values to be inserted may also be specified using keyword
arguments.
Values will be inserted from one of several sources. The
sources, in the order in which they are consulted, are:
o Keyword arguments,
o The 'client' argument,
o The 'mapping' argument,
o The keyword arguments provided when the object was
created, and
o The 'mapping' argument provided when the template was
created.
