You can hack this on top of Markdown as it is, as long as you
don’t need to nest macros inside links. Then you can write this:


>     You are  %%USERNAME%%

>     Logged in at %%LOGINTIME%%

> 

>     Your browser is %%HTTP{"User-Agent"}%%

>     You are accessing from %%REMOTE_ADDR%%:%%REMOTE_PORT%%

> 

>     The time is now  %%TIME(timezone=%%USER{%%TZ%%}%%, fmt="HH:MM:SS")%%


like this:

    You are [USERNAME](macro:)
    Logged in at [LOGINTIME](macro:)

    Your browser is [HTTP{"User-Agent"}](macro:)
    You are accessing from [REMOTE_ADDR](macro:):[REMOTE_PORT](macro:)

    The time is now [TIME(timezone=USER{TZ},fmt="HH:MM:SS")](macro:)

Markdown makes this out of it:

    <p>You are <a href="macro:">USERNAME</a>
    Logged in at <a href="macro:">LOGINTIME</a></p>

    <p>Your browser is <a href="macro:">HTTP{“User-Agent”}</a>
    You are accessing from <a href="macro:">REMOTE<em>ADDR</a>:<a href="macro:">REMOTE</em>PORT</a></p>

    <p>The time is now <a href="macro:">TIME(timezone=USER{TZ},fmt=”HH:MM:SS”)</a></p>

Then you can you go in there and replace `<a>` tags with a `href`
of `macro:` by the result of evaluating their textual content.

Hmm, you’d have to be careful about your underscores and
asterisks; not to mention there’s a bug there in Markdown…
