-// RE2Cache is a simple wrapper around hash_map<> to store RE2 objects.
-//
-// To get a cached RE2 object for a regexp pattern string, create a ScopedAccess
-// object with a pointer to the cache object and the pattern string itself as
-// constructor parameters. If an RE2 object corresponding to the pattern string
-// doesn't already exist, it will be created by the access object constructor.
-// The access object implements operator const RE& and can therefore be passed
-// as an argument to any function that expects an RE2 object.
-//
-// RE2Cache cache;
-// RE2Cache::ScopedAccess foo(&cache, "foo");
-// bool match = RE2::FullMatch("foobar", foo);
