It would be nice to be able to tag a given package with multiple tags, e.g. gftp would be tagged gtk, x11, net (example shamelessly copied form RR) and lftp would be tagged cli, net.
fink list/info/apropos would show these tags and fink list would be able to filter the results based on them. This would help when choosing among packages that provide the same service, e.g. ftp, or when a user doesn’t want a given GUI framework, e.g. GTK.
