Aptitude included in Maverick by default

[Luke L]

I've never seen an argument about apt-get and aptitude that
conclusively listed the benefits of one over the other. Every time a
+1 is mentioned for X, someone else says "No no no, that USED to be
but Y has that now".

As an apt-getter, I use
install
update
upgrade
dist-upgrade
autoremove
apt-cache show
apt-cache search
dpkg -l | grep

Can aptitude duplicate this functionality with ease? Does it do all
things in any sort of superior way?
