Rewrites a JSON file to use Python's standard JSON pretty-print format,
|
||
|
|
so that subsequent runs of rebaseline.py will generate useful diffs
|
||
|
|
(only the actual checksum differences will show up as diffs, not obscured
|
||
|
|
by format differences).
|
||
|
|
|
||
|
|
Should not modify the JSON contents in any meaningful way.
