-// A class representing a filesystem URL which consists of origin URL,
-// type and an internal path used inside the filesystem.
-//
-// When a FileSystemURL instance is created for a GURL (for filesystem: scheme),
-// each accessor method would return following values:
-//
-// Example: For a URL 'filesystem:http://foo.com/temporary/foo/bar':
-//   origin() returns 'http://foo.com',
-//   mount_type() returns kFileSystemTypeTemporary,
-//   virtual_path() returns 'foo/bar',
-//   type() returns the same value as mount_type(),
-//   path() returns the same value as virtual_path(),
-//
-// All other accessors return empty or invalid value.
-//
-// FileSystemURL can also be created to represent a 'cracked' filesystem URL if
-// the original URL's type/path is pointing to a mount point which can be
-// further resolved to a lower filesystem type/path.
-//
-// Example: Assume a path '/media/removable' is mounted at mount name
-// 'mount_name' with type kFileSystemTypeFoo as an external file system.
-//
-// The original URL would look like:
-//     'filesystem:http://bar.com/external/mount_name/foo/bar':
-//
-// FileSystemURL('http://bar.com',
-//               kFileSystemTypeExternal,
-//               'mount_name/foo/bar'
-//               'mount_name',
-//               kFileSystemTypeFoo,
-//               '/media/removable/foo/bar');
-// would create a FileSystemURL whose accessors return:
-//
-//   origin() returns 'http://bar.com',
-//   mount_type() returns kFileSystemTypeExternal,
-//   virtual_path() returns 'mount_name/foo/bar',
-//   type() returns the kFileSystemTypeFoo,
-//   path() returns '/media/removable/foo/bar',
-//
-// Note that in either case virtual_path() always returns the path part after
-// 'type' part in the original URL, and mount_type() always returns the 'type'
-// part in the original URL.
-//
-// Additionally, following accessors would return valid values:
-//   filesystem_id() returns 'mount_name'.
-//
-// It is impossible to directly create a valid FileSystemURL instance (except by
-// using CreatedForTest methods, which should not be used in production code).
-// To get a valid FileSystemURL, one of the following methods can be used:
-// <Friend>::CrackURL, <Friend>::CreateCrackedFileSystemURL, where <Friend> is
-// one of the friended classes.
-//
-// TODO(ericu): Look into making virtual_path() [and all FileSystem API virtual
-// paths] just an std::string, to prevent platform-specific base::FilePath
-// behavior from getting invoked by accident. Currently the base::FilePath
-// returned here needs special treatment, as it may contain paths that are
-// illegal on the current platform.
-// To avoid problems, use VirtualPath::BaseName and
-// VirtualPath::GetComponents instead of the base::FilePath methods.
