How to create header.info file

[Pavel Lisy <pavel lisy gmail com>]

Hello

I've made my repository for CentOS (3/4/5) with createrepo version
0.4.9. 

It makes these files

repodata/filelists.xml.gz
repodata/other.xml.gz
repodata/primary.xml.gz
repodata/repomd.xml

Yum is working fine but on 

RHEL 4 I've got this error from up2date

An HTTP error occurred:
URL:
http://ftp-hk.tmapy.cz/tmapy-twist/centos/4/os/i386/headers/header.info
Status Code: 404
Error Message: Not Found

How can I create this file and other files in headers directory?
There is nothing in createrepo docs about these files. 

Can anybody help me?

Pavel
