# This module is based on the excellent work by Adam Bartoš who
|
|
# provided a lot of what went into the implementation here in
|
|
# the discussion to issue1602 in the Python bug tracker.
|
|
#
|
|
# There are some general differences in regards to how this works
|
|
# compared to the original patches as we do not need to patch
|
|
# the entire interpreter but just work in our little world of
|
|
# echo and prmopt.
