UEViewer exports a dialect of INI files that is not compatible with Python's ConfigParser.
|
|
Specifically, it allows values in this format:
|
|
|
|
[Section]
|
|
Key1
|
|
Key2
|
|
|
|
This is not allowed in Python's ConfigParser, which requires a '=' character after each key name.
|
|
To work around this, we'll modify the file to add the '=' character after each key name if it is missing.
