title: Perl script to find out add/edit or delete done by an user for a workspace in Perforce
body: <p>perforce list out the files submitted by an user i.e.
  p4 changes -u 
  what i would like to do is write a small function in perl which will find 
  what changes have been submitted by user 
  what operations has been performed for those changes i.e. add, edit or delete and print those .
  so logic is something like this 
  1. find changes submitted by an user
  2. what operation has been performed on those changes 
  result :
  user has 5 change list submitted after date ...
  5 add, 2 delete and 1 edit operation found in all changes.</p>
