cdrom vs /cdrom/cdrom and /cdorm/cdrom0

["H. S." <greatexcalibur@yahoo.com>]

I am looking for the meaning and differences in these files:
/cdrom
/cdrom/cdrom
/cdrom/cdrom0

Apparently, I got this setup when I installed, but I pretty quickly 
deleted /cdrom/cdrom and made mountpoing /cdrw to mount the 
reader/writer /dev/cdrw which was a link I created to /dev/hdd.

The /cdrom0 is a link to /cdrom, which is a mountpoint for /dev/hdc.

But quite honestly I am not clear what all these files /cdrom, 
/cdrom/cdrom0, /cdrom/cdrom actually stand for. Where can I find the 
details? And what if I wanted to set up these files as they were when I 
first installed Sarge? What document gives the original 'default' state 
of these files?

Thanks,
->HS
