The BeginLine and EndLine of an Object must use the same keyword.
When interpreting a Document, software MUST reject any document containing a
KeywordLine that starts with a keyword it doesn't recognize.
When interpreting a Document, software MUST ignore any KeywordLine that
starts with a keyword it doesn't recognize; future implementations MUST NOT
require current clients to understand any KeywordLine not currently
described.
The "opt" keyword is reserved for non-critical future extensions. All
implementations MUST ignore any item of the form "opt keyword ....." when
they would not recognize "keyword ....."; and MUST treat "opt keyword ....."
as synonymous with "keyword ......" when keyword is recognized.
The "opt" keyword was used until Tor 0.1.2.5-alpha for non-critical future
extensions. All implementations MUST ignore any item of the form "opt
keyword ....." when they would not recognize "keyword ....."; and MUST
treat "opt keyword ....." as synonymous with "keyword ......" when keyword
is recognized.
Implementations before 0.1.2.5-alpha rejected any document with a
KeywordLine that started with a keyword that they didn't recognize.
Implementations MUST prefix items not recognized by older versions of Tor
with an "opt" until those versions of Tor are obsolete.

by the given version of Tor." Otherwise, if the value begins with
some other string, Tor has upgraded to a more sophisticated
protocol versioning system, and the protocol is "a version of the
Tor protocol more recent than any we recognize."
The "r" entry for each router must appear first and is required. The
