How can I set the flag echo=False by default to all code, when precessing a python-script file with pweave.
Minimal example:
#' # Minimal example.
#' This is a minimal example, which
#' says 'hello' to you.
#+ echo=False
print('Hello')
#' The end.
Which gets processed by
# either: py to html
pypublish test.py
# or: py to markdown
pweave -f pandoc test.py
