  \Prog{Latex2man} is a tool to translate UNIX manual pages written with
  \LaTeX\ into a format understood by the UNIX \Cmd{man}{1}-command.
  Alternatively HTML, TexInfo, or \LaTeX\ code can be produced too.
  Output of parts of the text may be suppressed using the conditional text
  feature (for this, LaTeX generation may be used).

\section{Synopsis}
%%%%%%%%%%%%%%%%%%

\Prog{latex2man} \oOptArg{-t}{transfile}
                 \oOptArg{-c}{CSSfile}
                 \oOpt{-HMTL} \oOpt{-h} \oOpt{-V} \oOptArg{-C}{name} \TEXIbr
                 \oOptArg{-a}{char}
                 \Arg{infile}
                 \Arg{outfile}

\section{Description}
%%%%%%%%%%%%%%%%%%%%%
\Prog{Latex2man} reads the file \Arg{infile} and writes \Arg{outfile}. The
input must be a \LaTeX\ document using the \Prog{latex2man} \LaTeX\ package.
\Prog{Latex2man} translates that document into the \Cmd{troff}{1} format using
the \Opt{-man} macro package.

Using the \Opt{-H} option, HTML code can be produced, instead of
\Cmd{troff}{1}.
With this option you can, optionally, specify a \Arg{CSSfile} as an argument.
CSS (Cascading Style Sheets) allows you to control the appearance of the resulting HTML page.
See below for the names of CSS classes that are included in the HTML tags as attributes.

Using the \Opt{-T} option, TexInfo code can be produced, instead of
\Cmd{troff}{1}.

Using the \Opt{-M} option, \Cmd{troff}{1} input is produced.

Using the \Opt{-L} option, \LaTeX\ ouput can be produced, instead of
\Cmd{troff}{1}.


\section{Options}
%%%%%%%%%%%%%%%%%
\begin{Description}[\OptArg{-t}{transfile}]\setlength{\itemsep}{0cm}
\item[\OptArg{-t}{transfile}] Translation for user defined \LaTeX\ macros.
\item[\OptArg{-c}{CSSfile}]  If you use the \Opt{-H} you can also specify a file that contains CSS
     style sheets. The link to the CSS file is inserted into the generatedHTML output using the
     specified \Arg{CSSfile} filename.
\item[\Opt{-M}] Produce output suitable for the \Cmd{man}{1} command (default).
\item[\Opt{-H}] Instead of producing output suitable for the \Cmd{man}{1}
     command, HTML code is produced (despite the name of the command).
\item[\Opt{-T}] Instead of producing output suitable for the \Cmd{man}{1}
     command, TexInfo code is produced (despite the name of the command).  The
     generated \File{.texi}-file may be processed with \Cmd{makeinfo}{1}
     (to produce an \File{.info}-file) which in turn may be installed using
     \Cmd{install-info}{1}.  The Info tags \verb+@dircategory+ and
     \verb+@direntry+ are provided.
\item[\Opt{-L}] The \LaTeX\ source is written to the \Arg{outfile}. This is
     useful in conjunction with the \OptArg{-C}{name} option.
\item[\OptArg{-C}{name}] Output the conditional text for \Arg{name}.  If more
     than one name should be given use quotes: \OptArg{-C}{'name1 name2 ...'}\\
     The following names are defined automatically:
     \begin{itemize}
        \item \Opt{-H} defines \texttt{HTML}
        \item \Opt{-T} defines \texttt{TEXI}
        \item \Opt{-M} defines \texttt{MAN}
        \item \Opt{-L} defines \texttt{LATEX}
     \end{itemize}
 \item[\OptArg{-a}{char}] Is used only in conjunction with -T.\\
     Background:\\
     TexInfo ignores all blanks before the first word on a new line. In order
     to produce some additional space before that word (using \Bs SP) some
     character has to be printed before the additional space. By default this
     is a . (dot).  The \Arg{char} specifies an alternative for that first
     character.  Giving a blank to
     \Opt{-a} supresses the indentation of a line.\\
     Note: only for the first \Bs SP of a series that \Arg{char} is printed.
\item[\Opt{-h}] Show a help text.
\item[\Opt{-V}] Show version information.
\end{Description}

\section{\LaTeX\ commands}
%%%%%%%%%%%%%%%%%%%%%%%%%%

The \LaTeX\ package \texttt{latex2man} is used to write the Man-pages with
\LaTeX.  Since we translate into other text formats, not all \LaTeX\ stuff can
be translated.

\subsection{Package Options}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%
The \texttt{latex2man} package accepts the following options:

\begin{description}\setlength{\itemsep}{0cm}
\item[fancy]    use the  \LaTeX\ package \texttt{fancyheadings}.
\item[fancyhdr] use the  \LaTeX\ package \texttt{fancyhdr}.
\item[nofancy] neither the \LaTeX\ package \texttt{fancyheadings} nor
     \texttt{fancyhdr} are used.
\end{description}

The default option may be specified in the file \texttt{latex2man.cfg}.

\subsection{Package Specific Environments}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

The following environments are provided by the package:
\begin{description}\setlength{\itemsep}{0cm}
\item[\Bs begin\{Name\}\{chapter\}\{name\}\{author\}\{info\}\{title\} ] The
     \texttt{Name} environment takes five arguments: 1.\ the Man-page chapter,
     2.\ the name of the Man-page, 3.\ the author, 4.\ some short information
     about the tool printed in the footline of the Man-page, and 5.\ a text
     which is used as title, for HTML and \LaTeX\ (it's ignored for output of
     the Man-page or TeXinfo. The \texttt{Name} environment must be the first
     environment in the document. Processing starts with this environment. Any
     text before this is ignored (exception: the \verb+setVersion+ and
     \verb+setDate+ commands).  (Note: all arguments of \Bs begin\{Name\} must
     be written on one line).
\item[\Bs begin\{Table\}\Lbr width\Rbr\{columns\}] The \texttt{Table}
     environment takes two arguments: the first optional one specifies
     a width of the last column, the second one gives the number of columns.
     For example:

     \verb+\begin{Table}[2cm]{3}+            \\
     \verb+ Here & am  & I   \\\hline+  \\
     \verb+  A 1 & A 2 & A 3 1 2 3 4 5 A 3 1 2 3 4 5 \\+        \\
     \verb+  B 1 & B 2 & B 3 \\+        \\
     \verb+\end{Table}+

     will be typeset as:

     \begin{Table}[2cm]{3}
       Here & am  & I   \\\hline
        A 1 & A 2 & A 3 1 2 3 4 5 A 3 1 2 3 4 5\\
        B 1 & B 2 & B 3 \\
     \end{Table}

     If no optional \emph{width} argument is given, all entries are
     typeset left justified.
     The \emph{width} is a length measured absolutly in \emph{cm}.
     Processing with \LaTeX\ a \verb+p{width}+ column is typeset
     as last column. The translation to \Cmd{troff}{1} commands
     results in a \texttt{lw(width)} column specification. Translating
     to HTML and TexInfo ignores the \emph{width} parameter.

     \verb+\hline+ may be used.

     If the Man-page is formatted with \Cmd{troff}{1} and tables are used, the
     \Cmd{tbl}{1} preprocessor should be called, usually by giving
     a \Opt{-t} to the call of \Cmd{troff}{1}. When viewing the generated
     manula page using \Cmd{man}{1}, \Cmd{tbl}{1} is called automatically.
\item[\Bs begin\{Description\}] is the same as \Bs begin\{description\}
\item[\Bs begin\{Description\}\Lbr label\Rbr] is similar to
     \Bs begin\{description\}, but the item labels have at minimum the size
     of the (optional) word \emph{label}. The difference is visible only
     in the DVI and PDF-output, not in the troff, TexInfo or HTML output.
     \begin{description}
     \item[a]   \Bar a \verb+\begin{description}+
     \item[ab]  \Bar ab
     \item[abc] \Bar abc
     \end{description}
     \begin{Description}
     \item[a]  \Bar a \verb+\begin{Description}+
     \item[ab] \Bar ab
     \item[abc]\Bar abc
     \end{Description}
     \begin{Description}[ab]
     \item[a]   \Bar a \verb+\begin{Description}[aa]+
     \item[ab]  \Bar ab
     \item[abc] \Bar abc
     \end{Description}
\end{description}

\subsection{Accepted \LaTeX\ Environments}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\begin{itemize}\setlength{\itemsep}{0cm}
\item \texttt{description}

\end{description}

\subsection{Accepted \LaTeX\ Macros}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

The following standard \LaTeX\ commands are accepted:
\begin{description}\setlength{\itemsep}{0cm}
\item[\Bs section\{..\}] The \texttt{section} macro takes one argument: the
     name of the Man-page section.  Each Man-page consists of several sections.
     Usually there are the following sections in a Man-page: \emph{Name}
     (special handling as environment, c.f.\ above), \emph{Synopsis},
     \emph{Description}, \emph{Options}, \emph{Files}, \emph{See Also},
     \emph{Diagnostics}, \emph{Return Values}, \emph{Bugs}, \emph{Author},
     \emph{version}, etc.

     \emph{Synopsis} must be the first section after the \texttt{Name}
     environment.

     Note: Do not use \LaTeX-macros in section names.
\item[\Bs subsection\{..\}] works as well as
\item[\Bs subsubsection\{..\}] those.
\item[\Bs emph\{..\}] \verb+\emph{example}+ is typeset as \emph{example}.
\item[\Bs textbf\{..\}] \verb+\textbf{example}+ is typeset as \textbf{example}.
\item[\Bs texttt\{..\}]\verb+\texttt{example}+ is typeset as \texttt{example}.
\item[\Bs underline\{..\}]\verb+\underline{example}+ is typeset as
     \underline{example of underline}.
\item[\Bs date\{..\}] uses \verb+..+ as date.
\item[\Bs verb+..+] but only + is allowed as delimiter.
\item[\$$<$\$]  is typeset as $<$.
\item[\$$>$\$]  is typeset as $>$.
\item[\$$<=$\$] is typeset as $<=$.
\item[\$$>=$\$] is typeset as $>=$.
\item[\$$=$\$]  is typeset as $=$.
\item[\$$<>$\$] is typeset as $<>$.
\item[\$\Bs ge\$] is typeset as $\ge$.
\item[\$\Bs le\$] is typeset as $\le$.
\item[\$\Bs leftarrow\$] is typeset as $\leftarrow$.
\item[\$\Bs Leftarrow\$] is typeset as $\Leftarrow$.
\item[\$\Bs rightarrow\$] is typeset as $\rightarrow$.
\item[\$\Bs Rightarrow\$] is typeset as $\Rightarrow$.
\item[\Bs \{] is typeset as \{.
\item[\Bs \}] is typeset as \}.
\item[\Bs \$] is typeset as \$.
\item[\Bs \Dollar] is typeset as \Dollar, should be used inside macro
     arguments.
\item[\Bs \_] is typeset as \_.
\item[\Bs \&] is typeset as \&.
\item[\Bs \#] is typeset as \#.
\item[\Bs \%] is typeset as \%.
\item[\Bs ,] is typeset as smaller blank -\,- (between the two -)
\item[\Bs -]  is used to mark hyphenation in a word.
\item[\Bs \Bs] is typeset as a linebreak or marks the end of a column in the
     \texttt{Table} environment.
\item[\Bs ] (a \Bs\ followed by a blank) is typeset as a blank,
     although it cannot be used at the beginning of a line to make indentation
     (see the \texttt{\Bs SP} command).
\item[\Tilde] is typeset as a blank.
\item[\Bs copyright] is typeset as \copyright.
\item[\Bs noindent]
\item[\Bs hline] inside a \texttt{Table} environment.
\item[\Bs item] inside a \texttt{itemize}, \texttt{enumerate}, or
     \texttt{description} environment.
\item[\Bs today] \today\ (see also the \texttt{rcsinfo} \LaTeX\ package).
\item[\Bs ss,\Bs"a, ...] \Bs ss = \ss, \Bs"a = \"a, \Bs"o = \"o, \Bs"u = \"u,
     \Bs"A = \"A, \Bs"O = \"O, \Bs"U = \"U. It is allowed to surround these
     macros in \{ and \} in all places, even inside other macros, e.g.
     \begin{verbatim}
     \textbf{\"a\"o\"u\"A\"O\"U\ss}
     \textbf{\"a}{\"o}{\"u}{\"A}{\"O}{\"U}{\ss}}
     \textbf{äöüÄÖÜß}
     \end{verbatim}

     \textbf{\"a\"o\"u\"A\"O\"U\ss {\"a}{\"o}{\"u}{\"A}{\"O}{\"U}{\ss} äöüÄÖÜß}

     If these letters are used in their LATIN-1 8-bit coding, they are
     translated into the equivalent letter of the desired output format.
     E.g. \texttt{Ä} becomes \texttt{\&Auml}; in HTML and \texttt{@"A}
     in texinfo.
\item[\Bs input\{..\}] Read and process the given filename.
\end{description}

Please note: the name of the \LaTeX-macros and its arguments must be contained in one line.

\subsection{Conditional Text}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\Prog{latex2man} preprocesses the \LaTeX\ input to allow text to be used
conditionally. A special sort of \LaTeX\ comment is used for that purpose.
\begin{itemize}\setlength{\itemsep}{0cm}
\item \Percent@\Percent\ IF \emph{condition} \Percent@\Percent
\item \Percent@\Percent\ ELSE \Percent@\Percent
\item \Percent@\Percent\ END-IF \Percent@\Percent
\end{itemize}

A line must contain only such a comment and nothing else.  \emph{condition} is
a boolean expression containing ``names'' and operators.  The names given with
the \OptArg{-C}{name} option have the value ``true'', while all other names
occuring in the expression are assumed to be ``false''.  If the evaluation of
the boolean expression results in the value ``true'', the text in the
``then''-part is used and the text in the optional ``else''-part is skipped
(and vice versa).  The \texttt{IF/ELSE/END-IF} may be nested.  As boolean
operators the following are allowed:

\begin{Table}{2}
\Bar\Bar & boolean or   \\
\&\&     & boolean and  \\
!        & negation
\end{Table}

( and ) for grouping are allowed.

\noindent
For example:\\
\Percent@\Percent\ IF abc                    \Percent@\Percent\\
\verb+    +abc set\\
\verb+    +\Percent@\Percent\ IF xyz         \Percent@\Percent\\
\verb+       +xyz set\\
\verb+    +\Percent@\Percent\ ELSE           \Percent@\Percent\\
\verb+       +xyz NOT set\\
\verb+    +\Percent@\Percent\ END-IF         \Percent@\Percent\\
\Percent@\Percent\ ELSE                      \Percent@\Percent\\
\verb+    +abc NOT set\\
\verb+    +\Percent@\Percent\ IF xyz \Bar\Bar\ !XYZ \Percent@\Percent\\
\verb+       +xyz OR !XYZ set\\
\verb+    +\Percent@\Percent\ ELSE           \Percent@\Percent\\
\verb+       +xyz OR !XYZ NOT set\\
\verb+    +\Percent@\Percent\ END-IF         \Percent@\Percent\\
\Percent@\Percent\ END-IF                    \Percent@\Percent

\noindent
Run this manual page through \Prog{latex2man} with e.g.\
\OptArg{-C}{'abc XYZ'} and have a look to the generated output.

\subsection{Translation of User Defined Macros}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

The user macro translation file (given by the \oOptArg{-t}{transfile}) contains
\Prog{Perl} commands specifying the translation of \LaTeX\ macros defined by
the user. These macros may have none, one or two arguments. The following code
is expected:

\begin{itemize}\setlength{\itemsep}{0cm}
\item Comments start with a \# up to the end of the line.
\item For a macro \verb+\foo+ with no arguments, the following code must be
     specified:
     \begin{description}\setlength{\itemsep}{0cm}
       \item[Translation to Man-Pages]\TEXbr
            \verb+$manMacro{'foo'}  = '...';+
       \item[Translation to HTML]\TEXbr
            \verb+$htmlMacro{'foo'} = '...';+
       \item[Translation to TexInfo]\TEXbr
            \verb+$texiMacro{'foo'} = '...';+
     \end{description}

     where \verb+...+ is the translation.

\item For a macro \verb+\foo{..}+ with one argument, the following code must be
     specified:
     \begin{description}\setlength{\itemsep}{0cm}
       \item[Translation to Man-Pages]\TEXbr
            \verb+$manMacro1a{'foo'}  = '...';+\\
            \verb+$manMacro1b{'foo'}  = '...';+
       \item[Translation to HTML]\TEXbr
            \verb+$htmlMacro1a{'foo'} = '...';+\\
            \verb+$htmlMacro1b{'foo'} = '...';+

       \item[Translation to TexInfo]\TEXbr
            \verb+$texiMacro1a{'foo'} = '...';+\\
            \verb+$texiMacro1b{'foo'} = '...';+
     \end{description}

     where \verb+...+ is the translation. The \verb+1a+ code is used before the
     argument, while \verb+1b+ is typeset after the argument is set.

\item For a macro \verb+\foo{..}{..}+ with two arguments, the following code
     must be specified:
     \begin{description}\setlength{\itemsep}{0cm}
     \item[Translation to Man-Pages]\TEXbr
          \verb+$manMacro2a{'foo'}  = '...';+\\
          \verb+$manMacro2b{'foo'}  = '...';+\\
          \verb+$manMacro2c{'foo'}  = '...';+
     \item[Translation to HTML]\TEXbr
          \verb+$htmlMacro2a{'foo'} = '...';+\\
          \verb+$htmlMacro2b{'foo'} = '...';+\\
          \verb+$htmlMacro2c{'foo'} = '...';+
     \item[Translation to TexInfo]\TEXbr
          \verb+$texiMacro2a{'foo'} = '...';+\\
          \verb+$texiMacro2b{'foo'} = '...';+\\
          \verb+$texiMacro2c{'foo'} = '...';+
     \end{description}

     where \verb+...+ is the translation. The \verb+2a+ code is used before the
     first argument, \verb+2b+ between the two arguments and \verb+2c+ is
     typeset after the second argument is set.
\item The file \File{latex2man.trans} contains some example code.
\end{itemize}

\subsection{Verbatim Environment}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\begin{verbatim}
This
    {is}
        \texttt{a}
                  $test$
                         _of_
verbatim
<this is no HTML tag> and no @* TexInfo command
\end{verbatim}

\subsection{Subsection works}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

This is a \verb+\subsection+.

\subsubsection{Subsubsection works}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

This is a \verb+\subsubsection+.

\subsubsection{Subsubsection still works}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

This is another \verb+\subsubsection+.


\subsection{General Remarks}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\begin{enumerate}\setlength{\itemsep}{0cm}
\item Empty lines are typeset as paragraph separators.
\item The arguments of the \LaTeX\ commands must not be split over several
     lines.
\item Do not nest calls to macros.
\item Except the mentioned environment and macros, the usage of other \LaTeX\
     environments or macros are not translated. Their usage will cause garbage
     in the output.
\item \Prog{latex2man} requires Perl version $>=$ 5.0004\_03.
\item If you want to install the system with the distributed \File{Makefile},
     you need GNU-\Prog{make}. If you don't have it, you should execute the
     steps shown in the \File{Makefile} manually.
\end{enumerate}

\section{CSS classnames}

     The table below shows the names of CSS classes that will be included in the HTML tags as attributes.
     You can specify the CSS style properties in the \Arg{CSSfile} for these classes:

\section{Some Bug Fix Tests}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% TODO: HTML: a blank line after \begin{description} should not emit a <p>
\begin{description}
\item[Leading . and ']
%%%%%%%%%%%%%%%%%%%%%%
Now leading . and ' in generation troff output should work propperly,
since a \verb+\&+ is added. Therfore the \verb+\Dot+ macro has been deleted.\\
Thanks to \Email{Frank.Schilder@Mathematik.Tu-Ilmenau.De}.\\
Testcase 1:
\begin{description}
\item['\Bs n'] ...
\end{description}
Testcase 2:\\
\File{.foobar}
Testcase 3:\\
\Dots

abc \Dots abc . efg ' 123

\item[\% in verbatim] A \% in a \Bs verb and verbatim-environment was not
     emitted correctly.  Thanks to Aleksey Nogin \Email{nogin@cs.caltech.edu}
     for the bug report and bug fix.

\verb+ % abc+
