easy as can be:
$ dpkg --get-selections|grep -e '\binstall$' > packages
That file contains the name of every package you have installed. The magic
grep addition is because the output also lists packages which are not fully
removed and what not.
On the new box (or whereever):
# dpkg --set-selections < packages
# apt-get dselect-upgrade
and it will install everything. *Warning* only do this on a machine after a
fresh install. The set-selections command will NOT remove the existing
packages, only add new ones.
