 %%% TUGboat changes are public domain.
 %%% 
 %%% Modified for TUGboat from abbrvurl.bst:
 %%%   New entry types: @ctan (see ctanbib); 
 %%%                    @online and @software (aliases for @misc).
 %%%   For @misc, the editor field is accepted along with author.
+%%%   For @misc, the organization field is output.
 %%%   New field bookauthor for @incollection and @inproceedings.
 %%%   Abbreviate "page(s)" to "p(p).",
 %%%     "volume" to "vol.",
 %%%     "editor(s)" to "ed(s).",
 %%%     "edition" to "ed.".
 %%%   Output "Ph.D." rather than "PhD".
-%%%   Output "No." and "no." for number field.
-%%%   Omit spaces between author initials, like "A.B. Smith".
+%%%   In number field, output "No." and "no.".
+%%%   In month field, output numbers 01..12 as our preferred abbreviations.
+%%%   Omit spaces between author initials, as in "A.B. Smith".
 %%%   Set urlintro="" and onlinestring="" to omit labels from output.
 %%%   Use \url instead of \href, so we don't require hyperref.
 %%%   Always use https://doi.org/ for the doi url; omit "doi:" from output.
 %%%   If doi or howpublished is present, omit url, since in practice
 %%%     they are usually all the same thing. Should check if
-%%%     howpublished is in fact a url, though.
+%%%     howpublished is in fact a url, but we currently don't.
 %%%   Truncate long author lists in format.names (max.names, trunc.num);
 %%%     omit "and" from author lists, per Oren P.
 %%%   Use \emph instead of \em so we get automatic italic corrections.
 %%%   New fields for editors:
 %%%     "journaltie" - ~ instead of space after journal name.
-%%%     "newpage" - force page break after entry;
+%%%     "monthtie" - ~ instead of space after month name.
+%%%     "newpage" - force page break after entry.
 %%%     "nowarning" - if set, omit empty field warnings from output.check.
+%%%     "pagesnodashify" - if set, don't convert - to -- in pages field.
 %%%     "prebibitem" - material output before \bibitem, with newline appended
 %%%       (for example, section headings).
-%%%     "urlnewline" - force line break before url or doi value;
+%%%     "urlnewline" - force line break before url or doi value.

+\par\smallskip\noindent
 They provide \textbf{an article template}, information for authors and
 reviewers, and the complete run of all published \TUB\ issues, among
 other things.
 
-The macros are released for general use, and are distributed via \CTAN{}
-(directory \CTANref{tub-latex}) in the usual \LaTeX{} way as files
-\path|tugboat.dtx| and \path|tugboat.ins|.  When the\,\verb|.ins| file
-is processed by \LaTeX{}, the files \path|ltugboat.cls| and
-\path|ltugbib.bst| (for use with articles) and \path|ltugcomn.sty| (a
-cooking pot of perhaps-useful macros, for documentation, etc.)\ are
-produced.  (\path|ltugproc.cls| is also produced for compatibility, but
-is no longer used for proceedings or anything else.)

-
-\section{Divisions of the paper}
-\label{sec:divs-paper}
-
-Papers in \TUB{} may be subdivided in the normal way of a \LaTeX{}
-article (the classes are defined in terms of \LaTeX{}'s
-\clsname{article} class).  Thus the author may use \cs{section},
-\cs{subsection}, \dots, \cs{paragraph} commands (but \cs{part} and
-\cs{subparagraph} from \clsname{article} are suppressed, and
-\cs{chapter}, which doesn't even appear in the parent class, receives
-the same treatment).
-
-Authors may note that the style of ordinary issues of \TUB{} makes
-no distinction between the titles of the divisions; the visual style
-relies on the section numbers to indicate where the divisions lie in
-the hierarchy.  If you use \cs{paragraph}, consider ending the paragraph
-label with a period; sometimes it is helpful, sometimes not.
-
-For references to numbered sections, our style is to always use the word
-`Section' in the text, e.g.,\\
-\verb|Section~\ref{sec:whatever}|\\
-without worrying about whether it is technically a sub(sub)section.
-It's also ok to use the section sign~\S{}, if that suits the material
-better.
-
-Reference can also be made to the `title' of divisions of the paper,
-whether they are numbered or not. The \cs{nameref} command (which uses
-the technique developed for the \textsf{hyperref} package
-\cite{Rahtz:hyperref:1997}) permits such references; for example, the
-present section was introduced by:
-\begin{verbatim}[\small]
-\section{Divisions of the paper}
-\label{sec:divs-paper}
-\end{verbatim}
-and the command \verb|\nameref{sec:divs-paper}| produces

-literal text of section titles often results in awkward results. We
-recommend numbered references in general.

-\subsection{Abstracts}
-
-The \clsname{ltugboat} class provides two environments for abstracts,
-\envname{abstract} and \envname{longabstract}. The \envname{abstract}
-environment simply typesets its body as an un-numbered section whose
-title is `Abstract'. The \envname{longabstract} environment typesets its

+\begin{cmdlist}\raggedright
+\item[\cs{cmd}] Typeset a control sequence name:\\
+  \verb|\cs{fred}| produces \cs{fred}.
+
+\item[\Dash] Typeset an em-dash, ignoring preceding and following space,
+  surrounded by thin spaces, only breakable after the dash; this
+  is our preferred method of specifying an em-dash in running text, over

+
+\item[\meta{var}] Typeset meta-syntactic text:\\
+  \verb|\meta{fred}| produces \meta{fred}.
+
+\item[\tbcode{text}] Literal text, such as class names, package names,
+filenames, environment variables, etc. The text is typeset in typewriter

-Furthermore, for the printed (visible) \TUB\ page, nowadays we typically
-prefer to omit a leading \texttt{http://} or \texttt{https://}. But for
-the link to actually work in the output \PDF\ or \HTML, the protocol is
-required (or it appears to be a local filesystem path). Therefore the
-\texttt{ltugboat} class provides (as of version 2.28, released
-January~2023) the command \cs{tburl} for this. Related commands
-\cs{tbsurl} for \texttt{https} and \cs{tbhurl} for \texttt{http} were
-defined in version~2.23 (March~2020).\footnote{All these commands are
-wrappers around \cs{hyper@linkurl}, and are due to Ulrike Fischer.
-\url{https://github.com/latex3/hyperref/issues/125}\raggedright}
+In short:
+
+\begin{enumerate}
+\item Please load either the \texttt{url} or (preferably) the
+\texttt{hyperref} package so that reasonable line breaking of urls can
+happen.
+
+\item Add \verb|\def\url{\tburl}| to your preamble and use \cs{url} in your
+document as usual. (It seems too intrusive for the \TUB\ classes to
+redefine something as fragile and widespread as \cs{url}.)
+\end{enumerate}
+The rest of this section is more details about the above.
+
+The main reason for preferring the above is that for the printed
+(visible) \TUB\ page, nowadays we typically prefer to omit a leading
+\texttt{https://}. But for the link to actually work in the output \PDF\
+or \HTML, the protocol is required (else the \PDF\ reader thinks it is
+a local filesystem path). Therefore the \texttt{ltugboat} class provides
+(as of 2023) the command \cs{tburl} for this.\footnote{This and related
+commands are wrappers around \cs{hyper@linkurl}.
+Thanks to Ulrike Fischer for doing the real work:
+\tburl{https://github.com/latex3/hyperref/issues/125}\raggedright}
 
 For example, the commands \verb|\tburl{tug.org}| and
 \verb|\tburl{https://tug.org}| both typeset the text `\texttt{tug.org}'
 (with the usual url line breaks possible) as a link to
 \url{https://tug.org}.
 
-Similarly, \verb|\tburl{http://example.org}| typesets the text
-`\texttt{example.org}' as a link to \url{http://example.org}, for the
-(unusual nowadays) case when \url{http} is required.
+Since so few web sites do not support https,
+\verb|\tburl{http://example.org}| typesets the full url as text
+`\texttt{http://example.org}' as a link to itself.  If it's desirable to
+elide the http://, the variant \cs{tbhurl} can be used.
 
-As shown, the correct protocol can be explicitly specified, and will be
-stripped for display.
+Thus, as shown, the correct protocol can be explicitly specified, and
+will be stripped for display. Just use \cs{tburl}.
 
-\cs{tburl} and related add the protocol and make live links if
-\texttt{hyperref} is loaded. Without \texttt{hyperref}, they are merely
-synonyms for \cs{url}. This is ok, and we still request that the
-protocol not be included; if live links are not being produced in the
-output, the printed url without the protocol suffices. (When a user
-copies/pastes url text into a browser, it will normally work.)
+In short, \cs{tburl} and related make live links and omit the protocol

 In order to keep using \cs{url} in a document body, we suggest
 \verb|\def\url{\tburl}|.

-\subsection{Url shortcuts}
+Finally, sometimes it is best to allow line breaks at hyphens in urls.
+We've found that this is not confusing in practice.  To enable this and
+\pkgname{hyperref} at the same time, it's necessary to load
+\pkgname{url} explicitly and enable the \tbcode{hyphens} option:
