.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\f(CW\*(C`Pod::LaTeX\*(C'\fR is a module to convert documentation in the Pod format
into Latex. The \fBpod2latex\fR  command uses
this module for translation.
.IX Xref "pod2latex"
.PP
\&\f(CW\*(C`Pod::LaTeX\*(C'\fR is a derived class from Pod::Select.
.SH "OBJECT METHODS"
.IX Header "OBJECT METHODS"
The following methods are provided in this module. Methods inherited
from \f(CW\*(C`Pod::Select\*(C'\fR are not described in the public interface.
.Sh "Data Accessors"
.IX Subsection "Data Accessors"
The following methods are provided for accessing instance data. These
methods should be used for accessing configuration parameters rather
than assuming the object is a hash.
.PP
Default values can be supplied by using these names as keys to a hash
of arguments when using the \f(CW\*(C`new()\*(C'\fR constructor.
.IP "\fBAddPreamble\fR" 4
.IX Item "AddPreamble"
Logical to control whether a \f(CW\*(C`latex\*(C'\fR preamble is to be written.
If true, a valid \f(CW\*(C`latex\*(C'\fR preamble is written before the pod data
is written.  This is similar to:
.Sp
.Vb 2
\&  \edocumentclass{article}
\&  \ebegin{document}
.Ve
.Sp
but will be more complicated if table of contents and indexing are required.
Can be used to set or retrieve the current value.
.Sp
.Vb 2
\&  $add = $parser->AddPreamble();
\&  $parser->AddPreamble(1);
.Ve
.Sp
If used in conjunction with \f(CW\*(C`AddPostamble\*(C'\fR a full latex document will
be written that could be immediately processed by \f(CW\*(C`latex\*(C'\fR.
.IP "\fBAddPostamble\fR" 4
.IX Item "AddPostamble"
Logical to control whether a standard \f(CW\*(C`latex\*(C'\fR ending is written to
the output file after the document has been processed.  In its
simplest form this is simply:
.Sp
.Vb 1
\&  \eend{document}
.Ve
.Sp
but can be more complicated if an index is required.
Can be used to set or retrieve the current value.
.Sp
.Vb 2
\&  $add = $parser->AddPostamble();
\&  $parser->AddPostamble(1);
.Ve
.Sp
If used in conjunction with \f(CW\*(C`AddPreaamble\*(C'\fR a full latex document will
be written that could be immediately processed by \f(CW\*(C`latex\*(C'\fR.
.IP "\fBHead1Level\fR" 4
.IX Item "Head1Level"
The \f(CW\*(C`latex\*(C'\fR sectioning level that should be used to correspond to
a pod \f(CW\*(C`=head1\*(C'\fR directive. This can be used, for example, to turn
a \f(CW\*(C`=head1\*(C'\fR into a \f(CW\*(C`latex\*(C'\fR \f(CW\*(C`subsection\*(C'\fR. This should hold a number
corresponding to the required position in an array containing the
following elements:
.Sp
.Vb 6
\& [0] chapter
\& [1] section
\& [2] subsection
\& [3] subsubsection
\& [4] paragraph
\& [5] subparagraph
.Ve
.Sp
Can be used to set or retrieve the current value:
.Sp
.Vb 2
\&  $parser->Head1Level(2);
\&  $sect = $parser->Head1Level;
.Ve
.Sp
Setting this number too high can result in sections that may not be
reproducible in the expected way. For example, setting this to 4 would
imply that \f(CW\*(C`=head3\*(C'\fR do not have a corresponding \f(CW\*(C`latex\*(C'\fR section
(\f(CW\*(C`=head1\*(C'\fR would correspond to a \f(CW\*(C`paragraph\*(C'\fR).
.Sp
A check is made to ensure that the supplied value is an integer in the
range 0 to 5.
.Sp
Default is for a value of 1 (i.e. a \f(CW\*(C`section\*(C'\fR).
.IP "\fBLabel\fR" 4
.IX Item "Label"
This is the label that is prefixed to all \f(CW\*(C`latex\*(C'\fR label and index
entries to make them unique. In general, pods have similarly titled
sections (\s-1NAME\s0, \s-1DESCRIPTION\s0 etc) and a \f(CW\*(C`latex\*(C'\fR label will be multiply
defined if more than one pod document is to be included in a single
\&\f(CW\*(C`latex\*(C'\fR file. To overcome this, this label is prefixed to a label
whenever a label is required (joined with an underscore) or to an
index entry (joined by an exclamation mark which is the normal index
separator). For example, \f(CW\*(C`\elabel{text}\*(C'\fR becomes \f(CW\*(C`\elabel{Label_text}\*(C'\fR.
.Sp
Can be used to set or retrieve the current value:
.Sp
.Vb 2
\&  $label = $parser->Label;
\&  $parser->Label($label);
.Ve
.Sp
This label is only used if \f(CW\*(C`UniqueLabels\*(C'\fR is true.
Its value is set automatically from the \f(CW\*(C`NAME\*(C'\fR field
if \f(CW\*(C`ReplaceNAMEwithSection\*(C'\fR is true. If this is not the case
it must be set manually before starting the parse.
.Sp
Default value is \f(CW\*(C`undef\*(C'\fR.
.IP "\fBLevelNoNum\fR" 4
.IX Item "LevelNoNum"
Control the point at which \f(CW\*(C`latex\*(C'\fR section numbering is turned off.
For example, this can be used to make sure that \f(CW\*(C`latex\*(C'\fR sections
are numbered but subsections are not.
.Sp
Can be used to set or retrieve the current value:
.Sp
.Vb 2
\&  $lev = $parser->LevelNoNum;
\&  $parser->LevelNoNum(2);
.Ve
.Sp
The argument must be an integer between 0 and 5 and is the same as the
number described in \f(CW\*(C`Head1Level\*(C'\fR method description. The number has
nothing to do with the pod heading number, only the \f(CW\*(C`latex\*(C'\fR sectioning.
.Sp
Default is 2. (i.e. \f(CW\*(C`latex\*(C'\fR subsections are written as \f(CW\*(C`subsection*\*(C'\fR
but sections are numbered).
.IP "\fBMakeIndex\fR" 4
.IX Item "MakeIndex"
Controls whether \f(CW\*(C`latex\*(C'\fR commands for creating an index are to be inserted
into the preamble and postamble
.Sp
.Vb 2
\&  $makeindex = $parser->MakeIndex;
\&  $parser->MakeIndex(0);
.Ve
.Sp
Irrelevant if both \f(CW\*(C`AddPreamble\*(C'\fR and \f(CW\*(C`AddPostamble\*(C'\fR are false
(or equivalently, \f(CW\*(C`UserPreamble\*(C'\fR and \f(CW\*(C`UserPostamble\*(C'\fR are set).
.Sp
Default is for an index to be created.
.IP "\fBReplaceNAMEwithSection\fR" 4
.IX Item "ReplaceNAMEwithSection"
This controls whether the \f(CW\*(C`NAME\*(C'\fR section in the pod is to be translated
literally or converted to a slightly modified output where the section
name is the pod name rather than \*(L"\s-1NAME\s0\*(R".
.Sp

(dependent on the value of \f(CW\*(C`Head1Level\*(C'\fR and \f(CW\*(C`LevelNoNum\*(C'\fR). Note that
subsequent \f(CW\*(C`head1\*(C'\fR directives translate to subsections rather than
sections and that the labels and index now include the pod name (dependent
on the value of \f(CW\*(C`UniqueLabels\*(C'\fR).
.Sp
The \f(CW\*(C`Label\*(C'\fR is set from the pod name regardless of any current value
of \f(CW\*(C`Label\*(C'\fR.
.Sp
.Vb 2
\&  $mod = $parser->ReplaceNAMEwithSection;
\&  $parser->ReplaceNAMEwithSection(0);
.Ve
.Sp
Default is to translate the pod literally.
.IP "\fBStartWithNewPage\fR" 4
.IX Item "StartWithNewPage"
If true, each pod translation will begin with a \f(CW\*(C`latex\*(C'\fR
\&\f(CW\*(C`\eclearpage\*(C'\fR.
.Sp
.Vb 2
\&  $parser->StartWithNewPage(1);
\&  $newpage = $parser->StartWithNewPage;
.Ve
.Sp
Default is false.
.IP "\fBTableOfContents\fR" 4
.IX Item "TableOfContents"
If true, a table of contents will be created.
Irrelevant if \f(CW\*(C`AddPreamble\*(C'\fR is false or \f(CW\*(C`UserPreamble\*(C'\fR
is set.
.Sp
.Vb 2
\&  $toc = $parser->TableOfContents;
\&  $parser->TableOfContents(1);
.Ve
.Sp
Default is false.
.IP "\fBUniqueLabels\fR" 4
.IX Item "UniqueLabels"
If true, the translator will attempt to make sure that
each \f(CW\*(C`latex\*(C'\fR label or index entry will be uniquely identified
by prefixing the contents of \f(CW\*(C`Label\*(C'\fR. This allows
multiple documents to be combined without clashing 
common labels such as \f(CW\*(C`DESCRIPTION\*(C'\fR and \f(CW\*(C`SYNOPSIS\*(C'\fR
.Sp
.Vb 2
\&  $parser->UniqueLabels(1);
\&  $unq = $parser->UniqueLabels;
.Ve
.Sp
Default is true.
.IP "\fBUserPreamble\fR" 4
.IX Item "UserPreamble"
User supplied \f(CW\*(C`latex\*(C'\fR preamble. Added before the pod translation
data. 
.Sp
If set, the contents will be prepended to the output file before
the translated data regardless of the value of \f(CW\*(C`AddPreamble\*(C'\fR.
\&\f(CW\*(C`MakeIndex\*(C'\fR and \f(CW\*(C`TableOfContents\*(C'\fR will also be ignored.
.IP "\fBUserPostamble\fR" 4
.IX Item "UserPostamble"
User supplied \f(CW\*(C`latex\*(C'\fR postamble. Added after the pod translation
data. 
.Sp
If set, the contents will be prepended to the output file after
the translated data regardless of the value of \f(CW\*(C`AddPostamble\*(C'\fR.
\&\f(CW\*(C`MakeIndex\*(C'\fR will also be ignored.
