Please Analyze This Script for me

My assignment is to take over scripting for our NT 4.0 network and I have no idea what any of the following means. I do know that the script doesn’t execute on every login. It’s supposed to only be run once when setting up a machine for a new network user.

@echo off
del c:\profile.prf > nul
echo checking / creating c:\my documents\exchange
c:
cd “c:\my documents”

md exchange
@echo
net use v: /d /yes > nul
net use v: \\server1\scripts > nul
v:
v:\perl.exe profile.pl

echo invoking newprof.exe, using c:\profile.prf
@echo
v:\newprof.exe -p c:\profile.prf -s -z
net use v: /d /yes > nul
@echo
echo done

Please email me directly if more space is needed in your explanation. Sorry I don’t have more points to give.
