* - file: Optional. The generated file this source map is associated with.

* - sections: A list of section definitions.
|

*
|
||
|
* Each value under the "sections" field has two fields:

* - offset: The offset into the original specified at which this section
|
||
|
* begins to apply, defined as an object with a "line" and "column"
|
||
|
* field.
|
||
|
* - map: A source map definition. This source map could also be indexed,
|
||
|
* but doesn't have to be.
|
||
|
*
|
||
|
* Instead of the "map" field, it's also possible to have a "url" field
|
||
|
* specifying a URL to retrieve a source map from, but that's currently
|
||
|
* unsupported.
|
