@@ -11,6 +11,17 @@ Bugs are not for asking questions about a problem you
are trying to solve that involve the use of uncompyle6 along the way,
although I may be more tolerent of this if you sponsor the project.
Bugs are also not for general or novice kind help on how to install
this Python program in your environment in the way you would like to
have it set up, or how to interpret a Python traceback e.g. that winds
up saying Python X.Y.Z is not supported.
For these kinds of things, you will save yourself time by asking
instead on forums like StackOverflow that are geared to helping people
for such general or novice kinds questions and tasks. And unless you
are a sponsor of the project, if your question seems to be of this
category, the issue may just be closed.
Also, the unless you are a sponsor of the project, it may take a
while, maybe a week or so, before the bug report is noticed, let alone
acted upon.
