+options:
+  -h, --help            show this help message and exit
+  -q Q                  Q = search pip requirements file for CVEs, e.g. dep/myreq.txt
+  -p P [P ...]          S = search one or more products, e.g. o:microsoft:windows_7 or o:cisco:ios:12.1 or
+                        o:microsoft:windows_7 o:cisco:ios:12.1. Add --only-if-vulnerable if only vulnerabilities that
+                        directly affect the product are wanted.
+  --only-if-vulnerable  With this option, "-p" will only return vulnerabilities directly assigned to the product. I.e. it
+                        will not consider "windows_7" if it is only mentioned as affected OS in an adobe:reader

+  -c C                  search one or more CVE-ID
+  -o O                  O = output format [csv|html|json|xml|cveid]
+  -l                    sort in descending mode
+  -n                    lookup complete cpe (Common Platform Enumeration) name for vulnerable configuration

+  -a                    Lookup CAPEC for related CWE weaknesses
