procmail syntax problem

[John Ericson <john@john.pp.se>]

I have a bit problem with 4 lines that lookes like this:

:0:
* ^Subject: 24 Hours of Slashdot Headlines For \
| ^Subject: \[ Slashdot Message \] Daily Headlines
in-slashdot_hl

The mail I receive looks like this in the header:

From: slashdot@slashdot.org
Subject: [ Slashdot Message ] Daily Headlines
To: john@john.pp.se

Now what I want to achieve is that if the incoming mail has a subject line
containing "24 Hours of Slashdot Headlines For" or 
"[ Slashdot Message ] Daily Headlines", it should be places in
in-slashdot_hl.

It works if I use:
* ^Subject: \[ Slashdot Message \] Daily Headlines
as only rule but I want to have an if .. or if ..

Could someone fill in the missing code? =)
