 ### Message ranges
 Various Gptcmd commands work over ranges of messages in a conversation. Ranges are specified either as the index (position) of a single message, or a space-separated pair of the inclusive indices of the beginning and end of an interval of messages. Unlike in many programming languages, messages are one-indexed (i.e. `1` refers to the first message, `2` to the second, etc.). A dot (`.`) refers either to the entire conversation or, in place of a numeric index, to either the beginning or end of the conversation. Negative indexing is supported (`-1` refers to the last message, `-2` to the penultimate, and so on).
