I post this just about monthly.  IF you do installs with aptitude (I can't
vouch for it working any other way):

 aptitude search '~i !~M' | tr -s ' ' | cut -f 2 -d ' ' 

will return a lovely list of all the _manually_ installed packages - no

The first part says show the Installed (Manual) packages, 'tr' eliminates
excess spaces, and cut finds just the second word (the package name).
