Whats the correct syntax for the two new web sources framework functions  
'ifoutput' and 'ifnotoutput'.

Is there an argument to be used along with them?

My try:

```
outputto "ARTIST"
ifoutput "ALBUMARTIST"
say "something smart"
```

Yes. They both take the name of a previously used output as parameter and have to be closed with endif.

> **IfOutput** S Check for content in output buffer named S.  
> **IfNotOutput** S Check for absence of content in output buffer named S.

```
outputto "coverurl"
ifoutput "TMP_SECONDARY"
    set "coverurl"
    sayoutput "TMP_SECONDARY"
    set "TMP_SECONDARY"
endif

```

I'll update the documentation accordingly.
