+ Options:
+ --cache Create ~/.devscripts_cache directory if it does not exist
+
+ Matching options: (see the manpage for further information)
+ --include-tags Set of tags to include
+ --include-tag-op Must all tags match for inclusion?
+ --exclude-tags Set of tags to exclude
+ --exclude-tag-op Must all tags match for exclusion?
+ --include-dists Set of distributions to include
+ --include-dist-op Must all distributions be matched for inclusion?
+ --exclude-dists Set of distributions to exclude
+ --exclude-dist-op Must all distributions be matched for exclusion?
+
+ Debtags options: (only list packages with matching debtags)
+ --debtags Comma separated list of tags
+ (e.g. implemented-in::perl,role::plugin)
+ --debtags-database Database file (default: /var/lib/debtags/package-tags)
+
+ Popcon options:
+ --popcon Sort bugs by package's popcon rank
+ --pc-vote Sort by_vote instead of by_inst
+ (see popularity-contest(8))
+ --pc-local Use local popcon data from last popcon run
