@title{R16 — Community-Driven Interactive Code Evaluation}

R16 is a "trick bot". It saves snippets of code, which can then be recalled and executed on user-provided input.

@@ 93,6 93,8 @@ The @tt{frontend} object in the configuration file can have the following keys a
@item{@tt{bot_token} must be a string containing your Discord bot token.}
@item{@tt{bot_prefix} is a string specifying the bot's trigger prefix. If not present, defaults to @code{"!rkt "}.}
@item{@tt{trick_prefix} is a string specifying the bot's shorthand prefix. If not present, defaults to @code{"!!"}.}
@item{@tt{delete_time} is a nonnegative integer specifying a time in seconds. If any invocation of R16 is deleted within this time, then R16 will also delete its response.
This helps with spam due to incorrect trick invocations. If not present, defaults to 5 minutes (300 seconds). Set to 0 to disable this feature.}
