Hi,

This issue has come up before, and as far as I know there is no 
multiline comment. However, there are a few ways of commenting out 
larges pieces of code.

- Use a good text editor, Kate (KDE) allows you to select the 20 lines 
and press Ctrl-D to comment them all at once.
- Use a setup like:
if(FALSE) {
line1
...
line20
}

And set FALSE to TRUE if you want to let the code be executed.

These are probably not the only ones, but this is what I could think of 
right now.

cheers and good luck,
Paul
