a simple CRUX prt-get question

now i am sure this is CRUX specific. i am very much hungry on getting an answer to this question as it is revolving in my brain since beginning. prt-get is a front-end to pkgutils, the CRUX ports-system, and it handles dependencies automatically while installing packages. i want to know why it does not handle dependencies while remove that specific package which is quite opposite to apt-get. i know we have "pkgfoster" available but why that "removal dependency-handling" was not built into prt-get when we have built "installation using dependencies". may be because of KISS approach but myself, being a newbie failed to see a connection. may you explain please ? -- http://arnuld.blogspot.com/
