+.Sh DESCRIPTION
+.Nm
+Dumps ASN.1 DER-encoded values.
+If one or more
+.Ar TypeName
+arguments are given, then
+.Nm
+will print the value in a JSON-like format using its knowledge of
+the ASN.1 modules defining those types, stopping at the first type
+for which it can successfully decode the value.
+If
+.Ar TypeNames
+are given, they must be the names of ASN.1 types exported by an
+ASN.1 modules that are compiled into
+.Nm .
+Use the
+.Fl Fl try-all-types
+option to attempt decoding as all ASN.1 types known to
+.Nm .
+If neither any
+.Ar TypeName
+nor
+.Fl Fl try-all-types
+are given, then the value will be parsed and displayed using just
+the self-describing nature of DER.
+.Pp
+Options supported:
+.Bl -tag -width Ds
+.It Fl i, Fl Fl no-indent
+Do not indent dump.
+.It Fl I, Fl Fl inner
+Try to parse inner structures of OCTET STRING and constructed values.
+.It Fl l, Fl Fl list-types
+List all types known to
+.Nm .
+.It Fl A, Fl Fl try-all-types
+Attempt to decode the value as any of all types known to
+.Nm .
+.It Fl S, Fl Fl raw-sequence
+If a value parses as a given
+.Ar TypeName
+but any bytes are left over, try to parse those separately as
+well until all bytes are consumed or an error occurs.
+.It Fl n, Fl Fl no-print
+For the case where
+.Fl A
+or
+.Fl Fl try-all-types
+or where a
+.Ar TypeName
+is given, do not output a JSON representation of the value, just
+attempt to decode it.
+This is useful for fuzzing.
+.It Fl q, Fl Fl quiet
+Similar to
+.Fl n, Fl Fl no-print
+but JSON output will be formatted, just not output.
+As with
+.Fl n, Fl Fl no-print,
+this option requires
+.Fl A / Fl Fl try-all-types
+or that a
+.Ar TypeName
+be given.
+This is useful for fuzzing.
+.It Fl Fl test-encode
+Check that encoding produces the same value as decoding.
+Useful for fuzzing.
+.It Fl Fl test-copy
+Test copy functions.
+Useful for fuzzing.
