/**
|
|
*
|
|
* * Backtick quotes are used for <code></code> spans.
|
|
*
|
|
* * You can use multiple backticks as the delimiters if you want to
|
|
* include literal backticks in the code span. So, this input:
|
|
*
|
|
* Just type ``foo `bar` baz`` at the prompt.
|
|
*
|
|
* Will translate to:
|
|
*
|
|
* <p>Just type <code>foo `bar` baz</code> at the prompt.</p>
|
|
*
|
|
* There's no arbitrary limit to the number of backticks you
|
|
* can use as delimters. If you need three consecutive backticks
|
|
* in your code, use four for delimiters, etc.
|
|
*
|
|
* * You can use spaces to get literal backticks at the edges:
|
|
*
|
|
* ... type `` `bar` `` ...
|
|
*
|
|
* Turns to:
|
|
*
|
|
* ... type <code>`bar`</code> ...
