rpmusage will display for each package, the last date it was used (in days). It can be used
to find unused packages. It use the atime field of all package's files to do this job.

it can be used without any argument, and then will apply on all packages
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-help\fR" 8
.IX Item "-help"
Print a brief help message and exits.
.IP "\fB\-man\fR" 8
.IX Item "-man"
Print the manual page and exits.
.IP "\fB\-version\fR" 8
.IX Item "-version"
Print the program release and exit.
.IP "\fB\-verbose\fR" 8
.IX Item "-verbose"
The program works and print debugging messages.
.IP "\fB\-use\-cache\fR" 8
.IX Item "-use-cache"
the rpm query may be long (10 to 30 s). If you will run an rpmorphan tool
several time, this option will allow to gain a lot of time :
it save the rpm query on a file cache (first call), then
use this cache instead quering rpm (others calls).
.IP "\fB\-clear\-cache\fR" 8
.IX Item "-clear-cache"
to remove cache file. Can be used with \-use\-cache to write
a new cache.
.IP "\fB\-exclude\fR" 8
.IX Item "-exclude"
this option will specify the packages to exclude from the output.
Can be used as '\-\-exclude pac1 \-\-exclude pac2'
or '\-\-exclude \*(L"pac1, pac2\*(R"'
.IP "\fB\-install\-time\fR" 8
.IX Item "-install-time"
install-time is a filter on the period from the package installation date to now (in days).
if set positive, it only allow packages installed before x days.
if set negative, it only allow packages installed since x days.
.IP "\fB\-access\-time\fR" 8
.IX Item "-access-time"
access-time is designed to filter packages which have not been used since x days.
.Sp
be careful : this option will slow the program
.IP "\fB\-fullalgo\fR" 8
.IX Item "-fullalgo"
for a small list of packages, rpmusage use a different quicker methode : rpm \-e \-\-test
.Sp
this option can be used to force the use of the full algo
.IP "\fB\-package\fR" 8
.IX Item "-package"
search if the given package(s) is(are) orphaned.
Can be used as '\-\-package pac1 \-\-package pac2'
or '\-\-package \*(L"pac1, pac2\*(R"'
.IP "\fB\-all\fR" 8
.IX Item "-all"
apply on all installed packages. The output should be interpreted.
For example lilo or grub are orphaned packages, but are necessary
to boot ...
.Sp
the \-install\-time and \-access\-time options may be useful to filter the list
