Options controlling Titles, File-Names and Sectioning

-t <top-page-title>

Same as setting: $TITLE = "<top-page-title>";
Name the document using this title.

-short_extn

Same as setting: $SHORTEXTN = 1;
Use a filename prefix of .htm for the produced HTML files. This is particularly useful for creating pages to be stored on CD-ROM or other media, to be used with operating systems that require a 3-character extension.

-long_titles <num>

Same as setting: $LONG_TITLES = <num>;
Instead of the standard names: node1.html, node2.html,... the filenames for each HTML page are constructed from the first <num> words of the section heading for that page, separated by the `_' character.
Commas and common short words (a an to by of and for the) are omitted from both title and word-count.

Warning: Use this switch with great caution. Currently there are no checks for uniqueness of names or overall length. Very long names can easily result from using this feature.

-custom_titles

Same as setting: $CUSTOM_TITLES = 1;
Instead of the standard names: node1.html, node2.html, ... the filenames for each HTML page are constructed using a Perl subroutine named custom_title_hook . The user may define his/her own version of this subroutine, within a .latex2html-init file say, to override the default (which uses the standard names). This subroutine takes the section-heading as a parameter and must return the required name, or the empty string (default).

-dir <output-directory>

Same as setting: $DESTDIR = "<output-directory>";
Redirect the output to the specified directory.
The default behaviour is to create (or reuse) a directory having the same name as the prefix of the document being processed.

-no_subdir

Same as setting: $NO_SUBDIR = 1;
Place the generated HTML files into the current directory. This overrides any $DESTDIR setting.

-prefix <filename-prefix>

Same as setting: $PREFIX = "<filename-prefix>";
The <filename-prefix> will be prepended to all .gif, .pl and .html files produced, except for the top-level .html file; it may include a (relative) directory path. This will enable multiple products of L^ATEX2HTML to peacefully coexist in the same directory. However, do not attempt to simultaneously run multiple instances of L^ATEX2HTML using the same output directory, else various temporary files will overwrite each other.

-auto_prefix

Same as setting: $AUTO_PREFIX = 1;
Constructs the prefix as `<title>-' to be prepended to all the files produced, where <title> is the name of the L<sup>A</sup>TEX file being processed. (Note the `-' in this prefix.)
This overrides any $PREFIX setting.

-no_auto_link

Same as setting: $NO_AUTO_LINK = 1;
If $NO_AUTO_LINK is empty and variables $LINKPOINT and $LINKNAME are defined appropriately (as is the default in the latex2html.config file), then a hard link to the main HTML page is produced, using the name supplied in $LINKNAME. Typically this is index.html; on many systems a file of this name will be used, if it exists, when a browser tries to view a URL which points to a directory. On other systems a different value for $LINKNAME may be appropriate. Typically $LINKPOINT has value $FILE.html, but this may also be changed to match whichever HTML page is to become the target of the automatic link.
Use of the -no_auto_link switch cancels this automatic linking facility, when not required for a particular document.

-split <num>

Same as setting: $MAX_SPLIT_DEPTH = <num>; (default is 8)
Stop splitting sections into separate files at this depth. Specifying -split 0 will put the entire document into a single HTML file. See below for the different levels of sectioning. Also see the next item for how to set a ``relative'' depth for splitting.

-split +<num>

Same as setting: $MAX_SPLIT_DEPTH = -<num>; (default is 8)
The level at which to stop splitting sections is calculated ``relative to'' the shallowest level of sectioning that occurs within the document. For example, if the document contains \section commands, but no \part or \chapter commands, then -split +1 will cause splitting at each \section but not at any deeper level; whereas -split +2 or -split +3 also split down to \subsection and \subsubsection commands respectively. Specifying -split +0 puts the entire document into a single HTML file.

-link <num>

Same as setting: $MAX_LINK_DEPTH = <num>; (default is 4)
For each node, create links to child nodes down to this much deeper than the node's sectioning-level.
Specifying -link 0 will show no links to child nodes from that page,
-link 1 will show only the immediate descendents, etc.
A value at least as big as that of the -split <num> depth will produce a mini table-of-contents (when not empty) on each page, for the tree structure rooted at that node.

When the page has a sectioning-level less than the -split depth, so that the a mini table-of-contents has links to other HTML pages, this table is located at the bottom of the page, unless placed elsewhere using the \tableofchildlinks command.

On pages having a sectioning-level just less than the -split depth the mini table-of-contents contains links to subsections etc. occurring on the same HTML page. Now the table is located at the top of this page, unless placed elsewhere using the \tableofchildlinks command.

-toc_depth <num>

Same as setting: $TOC_DEPTH = <num>; (default is 4)
Sectioning levels down to <num> are to be included within the Table-of-Contents tree.

-toc_stars

Same as setting: $TOC_STARS = 1;
Sections created using the starred-form of sectioning commands are included within the Table-of-Contents. As with L^ATEX, normally such sections are not listed.

-show_section_numbers

Same as setting: $SHOW_SECTION_NUMBERS = 1;
Show section numbers. By default section numbers are not shown, so as to encourage the use of particular sections as stand-alone documents. In order to be shown, section titles must be unique and must not contain inlined graphics.

-unsegment

Same as setting: $UNSEGMENT = 1;
Treat a segmented document (see the section about document segmentation) like it were not segmented. This will cause the translator to concatenate all segments and process them as a whole. You might find this useful to check a segmented document for consistency.

For all documents the sectioning levels referred to above are:

0	document
1	part
2	chapter
3	section
4	subsection
5	subsubsection
6	paragraph
7	subparagraph
8	subsubparagraph

These levels apply even when the document contains no sectioning for the shallower levels; e.g. no \part or \chapter commands is most common, especially when using L^ATEX's article document-class.
