What does httpd.conf,v file suppose to mean?

[pratapsingh]

Hello,

I hope this is the right place to ask this question. I am confused if we have httpd.conf file as apache configuration file then what does httpd.conf,v files suppose to mean. It has also virtual host entry as httpd.conf file. I found one strange issue with as I have cPanel running on my server, for some domain virtual host entries are missing from the main httpd.conf file these entries are available in httpd.conf,v file.Is there any link between these too?

I tried to find out the importance of this file but I failed any help in this regard would be really appreciated.
