Classes need class-level documentation. Doesn't have to be long, just a couple
of sentences that describe what they do.

[Alexandre Abreu, 2012/04/25 15:31:05]

Done.

+ public:
+  // |base_path_key| is the directory containing the per-extension description
+  // json files.  Relative file paths to extension files are resolved relative
+  // to this path.

[Finnur, 2012/04/25 13:33:45]

Suggest: |base_path_id| is the resource id of the base path containing the json
description of which extensions to load. File paths to extension files are
resolved relative to this path.

[Alexandre Abreu, 2012/04/25 15:31:05]

Done.

+  explicit ExternalFilesystemExtensionLoader(int base_path_key);

[Finnur, 2012/04/25 13:33:45]

Can you rename this to |base_path_id|?

[Alexandre Abreu, 2012/04/25 15:31:05]

Done.

This should be documented also.

[Alexandre Abreu, 2012/04/25 15:31:05]

Done.

+  // See the constructor's base_path_key.

[Finnur, 2012/04/25 13:33:45]

Suggest: The resource id of the base path containing the json file containing
which extensions to load.

[Alexandre Abreu, 2012/04/25 15:31:05]

Done.

+  int base_path_key_;

[Finnur, 2012/04/25 13:33:45]

Same here: base_path_id.

[Alexandre Abreu, 2012/04/25 15:31:05]

Done.

+
+  // Concrete path corresponding to the base_path_key_.

[Finnur, 2012/04/25 13:33:45]

Suggest: The path containing the json file containing which extensions to load.

[Alexandre Abreu, 2012/04/25 15:31:05]

Done.
