lsof utility for OpenBSD

["John D." <lists@webcrunchers.com>]

I found a number of sources for "lsof",   a utility commonly used in forensics and analysing currently opened files in a system.

I found one that runs on Solaris,  but none specifically that runs on OpenBSD.   
I searched through the OpenBSD archives,  and all I find is description of the program,  but no place where I can download it.    Does this utility come in the CD release?    Not having the current release CD's at the moment,  has inspired me to ask on this list.   Any URL's where I can extract this utility,  would be useful.

I'm basically re-vamping my collection of Forensics tools at the moment,  in anticipation of using them to analyse disk problems,  infections,  or other things relating to recovery of hacked systems.
