  * This is the meaning of the flags:
  *
  * write: write command (may modify the key space).
- * read-only: read-only command that will read data from keys without changing
- *            the content. Commands just returning information but not reading
- *            from keys are usually not regarded as read-only commands, however
- *            such commands will also lack the "write" and "admin" flags so
- *            can be detected. One example is "TIME".
+ * read-only: all the non special commands just reading from keys without
+ *            changing the content, or returning other informations like
+ *            the TIME command. Special commands such administrative commands
+ *            or transaction related commands (multi, exec, discard, ...)
+ *            are not flagged as read-only commands.
  * use-memory: may increase memory usage once called. Don't allow if out
  *    of memory.
  * admin: admin command, like SAVE or SHUTDOWN.
