@ Abhishek,

Yes, I knew that. Even `aptitude purge` == `apt-get remove --purge`. 
Also `aptitude purge` == `dpkg -P` in some cases, where dependecny 
doesn't make any sense.  We have seen deinstall(rc) packages while 
maintaining Ubuntu system, without any package dependency. For example 
if you install pidgin, it will also install pidgin-data, but while 
removing (aptitude purge pidgin), it will not purge pidgin-data, which 
was installed while installing pidgin. It will only un-install the 
pidgin-data. Now, check the stat of pidgin-data, It will show 
deinstall(rc). It happens while upgrading / maintaining your system for 
a long time, you will have bunch of such packages. And i am sure all / 
most of packages would not have any relation with dependencies.
