+
+/* Our command table.
+ *
+ * Every entry is composed of the following fields:
+ *
+ * name: a string representing the command name.
+ * function: pointer to the C function implementing the command.
+ * arity: number of arguments, it is possible to use -N to say >= N
+ * sflags: command flags as string. See below for a table of flags.
+ * flags: flags as bitmask. Computed by Redis using the 'sflags' field.
+ * get_keys_proc: an optional function to get key arguments from a command.
+ * This is only used when the following three fields are not
+ * enough to specify what arguments are keys.
+ * first_key_index: first argument that is a key
+ * last_key_index: last argument that is a key
+ * key_step: step to get all the keys from first to last argument. For instance
+ * in MSET the step is two since arguments are key,val,key,val,...
+ * microseconds: microseconds of total execution time for this command.
+ * calls: total number of calls of this command.
+ *
+ * The flags, microseconds and calls fields are computed by Redis and should
+ * always be set to zero.
+ *
+ * Command flags are expressed using strings where every character represents
+ * a flag. Later the populateCommandTable() function will take care of
+ * populating the real 'flags' field using this characters.
+ *
+ * This is the meaning of the flags:
+ *
+ * w: write command (may modify the key space).
+ * r: read command (will never modify the key space).
+ * m: may increase memory usage once called. Don't allow if out of memory.
+ * a: admin command, like SAVE or SHUTDOWN.
+ * p: Pub/Sub related command.
+ * f: force replication of this command, regarless of server.dirty.
+ * s: command not allowed in scripts.
+ * R: random command. Command is not deterministic, that is, the same command
+ * with the same arguments, with the same key space, may have different
+ * results. For instance SPOP and RANDOMKEY are two random commands. */
