+
+DESCRIPTION
+    "cpan-audit" is a command line application that checks the modules or
+    distributions for known vulnerabilities. It is using its internal
+    database that is automatically generated from a hand-picked database
+    <https://github.com/briandfoy/cpan-security-advisory>.
+
+    "cpan-audit" does not connect to anything, that is why it is important
+    to keep it up to date. Every update of the internal database is released
+    as a new version. Ensure that you have the latest database by updating
+    CPAN::Audit frequently; the database can change daily. You can use
+    enable a warning for a possibly out-of-date database by adding
+    "--fresh", which warns if the database version is older than a month:
+
+            % cpan-audit --fresh ...
+            % cpan-audit -f ...
+
+            % env CPAN_AUDIT_FRESH_DAYS=7 cpan-audit -f ...
+
+  Finding dependencies
+    "cpan-audit" can automatically detect dependencies from the following
+    sources:
+
+    "Carton"
+        Parses cpanfile.snapshot file and checks the distribution versions.
+
+    cpanfile
+        Parses cpanfile taking into account the required versions.
+
+    It is assumed that if the required version of the module is less than a
+    version of a release with a known vulnerability fix, then the module is
+    considered affected.
+
+  JSON data
+    If you request JSON output, the data looks like
+
+        {
+          "meta" : {
+              ... meta information ...
+          "dists": {
+            "<distribution1>": {
+              ... distribution info ...
+            }
+          }
+          "errors" : [
+            ... list of errors - if any ...
+          ]
+        }
+
+   Meta information
+    The meta data contains information about the run of "cpan-audit".
+
+        {
+          "args": [
+            "Mojo::File",
+            "Mojo::UserAgent",
+            "LWP::UserAgent"
+          ],
+          "cpan_audit": {
+            "version": "20230601.002"
+          },
+          "total_advisories": 19,
+          "command": "modules"
+        }
+
+    These information are shown
+
+    *   cpan_audit
+
+        The version of "cpan_audit" that is used for the audit
+
+    *   command
+
+        The command of "cpan_audit" that was run
+
+    *   args
+
+        Arguments for the command
+
+    *   total_advisories
+
+        Number of found advisories
+
+   Distribution information
+    For each distribution where at least one advisory was found, the JSON
+    looks like:
+
+        "Dist-Name": {
+          "queried_modules": [
+            "Queried::Namespace"
+          ],
+          "version": "Any",
+          "advisories": [
+            {
+              ... advisory data as in the audit database ...
+            },
+              ... more advisories ...
+          ]
+        },
+
+    The advisory data is basically the data from the database. So this
+    depends on what is known for the given advisory.
+
+    The distribution information contains:
+
+    *   version
+
+        The version (range) that is checked for advisories. If there's no
+        version specified, all versions are checked and the version is
+        report as "Any".
+
+    *   queried_modules
+
+        The actual namespaces queried, either from the command line or
+        another source, such as a cpanfile.
+
+    *   advisories
+
+        A list of all vulnerabilities found for the version range
+
+  Exit values
+    In prior versions, "cpan-audit" exited with the number of advisories it
+    found. Starting with 1.001, if there are advisories found, "cpan-audit"
+    exits with 64 added to that number. The maximum number of reported
+    advisories is 62, since values over 126 are spoken for.
+
+    If the option "--exit-zero" is set "cpan-audit" exits always with a
+    normal exit code (0). This allows to use "cpan-audit" in build
+    environments together with bash exit mode activated ("set -e").
+
+    *   0 - no advisories found
+
+    *   2 - problem with program invocation, such as bad switches or values
+
+    *   64+n - advisories found. Subtract 64 to get the advisory count, up
+        to 62 advisories
+
+    *   255 - unspecified program error
