// sorted array of resource name hashes; and |kResourceIndices|, an array of
// resource indices in the same order as |kResourceHashes|. So, if
// generated_resources.h contains |#define IDS_FOO 12345|, then for some index i
// kResourceHashes[i] = HASH("IDS_FOO") and kResourceIndices[i] = 12345. Both
// arrays are of length |kNumResources|.

// The definitions of the arrays are generated by generate_resources_map.py from
// the content of generated_resources.h.

// Length of |kResourceHashes| and |kResourceIndices|.
