* parsed to an object). According to the spec for indexed source maps, they
|

* have the following attributes:
|
|
*
|

* - version: Which version of the source map spec this map is following.
|
|
* - 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.
