21
|
|
|
* The most useful way to apply this is probably to... |
|
22
|
|
|
* - run this once before starting the work on a feature that touches emails, dumping the rendered templates |
|
23
|
|
|
* - run it again after the changes, dumping to another folder |
|
24
|
|
|
* - then diffing the resulting folders |
