If you try to uninstall some package and dpkg won't let you, then you
know that something's using it. :)
There are several other ways:
* Use dselect, and when you mark the package to remove you'll get a
dependency conflict resolution screen listing any packages that
depend on it. If you want to keep them, just press 'R' and then
Enter to revert back to the state before you tried to remove the
package.
* 'apt-get remove package' will list other packages that it's going to
remove and ask you if that's OK.
* Install the grep-dctrl package, which is amazingly useful. You can
then do things like 'grep-status
-XFPre-Depends,Depends,Recommends,Suggests package' to search for
packages that declare any kind of dependency on the named package
* Install the deborphan package from woody, which will tell you what
"orphan" libraries you have installed - that is, libraries on which
nothing depends. With a little care, most of these can be safely
removed.
