Package: popularity-contest
Severity: normal
Hi,
popularity-contest can have several usage. For example,
popularity-contest | grep '<OLD>'
will show me a list of packages I have not been used for more than three
months. Then, "popcon-largest-unused" sorts unused packets by size.
However, this output isn't totally accurate: some packages appear "old" but
I can't remove them because other (non-old) packages depend on them. Also,
some packages recommended or suggested by other are likely to be used in the
future.
Therefore, I propose the following simple shell script (named
"popcon-nodependency"): it filters the output of "popcon-largest-unused" to
display only packets that are not requested/recommended/suggested by other.
Regards.
