1. Introduction

DocBook-Install-mini-HOWTO is a detailed practical guide for novices to
quickly getting DocBook installed and processing sgml files into html, ps,
and pdf on a GNU/Linux system - other systems may be similar. Since setup of
DocBook requires files from several separately distributed packages, it can
be confusing for beginners.
-----------------------------------------------------------------------------

1.1. What is DocBook

DocBook is a Standard Generalized Markup Language (SGML) Document Type
Definition (DTD) that defines a set of textual document markup tags that work
much like the familiar HTML language used on the web.

DocBook is intended for the authoring of books and articles. As such, it
provides tags specifically designed to describe books and articles. For
instance, the <book> and <article> DocBook tags are used to create books and
articles. Within these documents, the <chapter>, <sect1>, and <para> tags are
used. DocBook SGML files are stored in text files with a sgml or gml suffix.

When processed, a single DocBook SGML file can output html, pdf, ps, txt and
other formats for both online and printed publication. The processing is
governed by stylesheets that can automatically generate a table of contents,
page numbering, chapter & section numbering, and other features.

DocBook is also designed for authoring unix manpages using <refentry>.
-----------------------------------------------------------------------------

1.2. Brief Overview

Here are brief descriptions of the packages we will work with in the next
sections:

OpenJade. OpenJade is an Standard Generalized Markup Language (SGML) and
Document Style Semantics and Specification Language (DSSSL) processor. It
processes DocBook sgml source files into html, tex, rtf, txt and others.
Openjade is the essential engine for converting a DocBook file into other
formats. The tex out format is used mostly as an intermediate format to
obtain dvi, pdf, and ps via TeX macros and dvi converters.

DocBook SGML DTD. The Document Type Definition (DTD) files are SGML files
that define the DocBook language. Its defines the valid tag set and rules of
their use. OpenJade requires access to the DTD files for every document type
that it parses.

ISO8879 ENTITY SGML. Entities define how to represent special characters that
have either no keyboard key or have special meaning in SGML. Examples
familiar from HTML include "&amp;"='&', "&gt;"='>', and "&lt;"='<'.

DocBook DSSSL. Document Style Semantics and Specification Language (DSSSL)
files (dsl suffix) for a particular DTD, in this case DocBook, specify how to
convert DocBook into html, rtf, tex etc.

SgmlTools-lite. Sgmltools is a frontend wrapper for running openjade and the
TeX macros jadetex and pdfjadetex, macros included with openjade. Converting
a DocBook file to ps or pdf is a two or three-step process. OpenJade outputs
a tex file which is the input of jadetex, to produce a dvi, and pdfjadetex,
to produce a pdf. A ps file is obtained by passing the dvi file through
dvips. The sgmltools script provides a single command to perform these tasks.

HTMLdoc. HTMLdoc is a free program for converting html files into a pdf or ps
file.

SGMLSpm and docbook2X. Together, these two are used to generate manpages.
SGMLSpm is a perl5 module library for processing parsed output from onsgmls,
a program included with OpenJade. SGMLSpm includes an application called
sgmlspl to use the SGMLSpm library. Sgmlspl requires "spec files", which are
available from various other sources on the Internet, for each type of
document transformation to be performed. DocBook2X is a package that provides
the spec files for transforming DocBook files into manpages.
-----------------------------------------------------------------------------

2. Download the Packages

In this section, we will locate and download the software on the Internet.
-----------------------------------------------------------------------------

2.1. OpenJade

OpenJade is an actively maintained open-source software project based on the
Jade package by [http://www.jclark.com/] James Clark. Download the lastest
stable release (1.3?) at:

[http://openjade.sourceforge.net/] http://openjade.sourceforge.net/

OpenJade also includes the OpenSP package and the TeX macros, jadetex and
pdfjadetex for converting files to dvi and pdf. The following program are
provided by this package:

��*�openjade

��*�onsgmls

��*�osgmlnorm

��*�ospam

��*�ospent

��*�osx


To use the jadetex and pdfjadetex for making dvi, ps, and pdf, you must have
a working TeX (tex) installation. If you do not have TeX, check with your
Linux distribution for a binary package that can be downloaded and installed.
Otherwise, you can download the teTeX distribution of TeX from:

[http://www.tug.org/tetex/] http://www.tug.org/tetex/
-----------------------------------------------------------------------------

2.2. DocBook SGML DTD

The DocBook DTD for SGML and XML are maintained by a technical committee at
[http://www.oasis-open.org/] Oasis-Open.ORG. Download the current version
(and any old versions you might need) of DocBook SGML at:

[http://www.oasis-open.org/docbook/sgml/index.html] http://www.oasis-open.org
/docbook/sgml/index.html
-----------------------------------------------------------------------------

2.3. ISO8879 ENTITY SGML

The entities define representations for special or untypeable symbols or
characters, including mathematical symbols, and the entities that you may be
familiar with from HTML. These entity files need to be installed for a proper
configuration.

��*�Resources at [http://www.oasis-open.org/] OASIS:

   ��+�[http://www.oasis-open.org/cover/topics.html#entities] http://
       www.oasis-open.org/cover/topics.html#entities

   ��+�[http://www.oasis-open.org/cover/ISOEnts.zip] http://
       www.oasis-open.org/cover/ISOEnts.zip

   ��+�[http://www.oasis-open.org/cover/isoENT-tar.gz] http://
       www.oasis-open.org/cover/isoENT-tar.gz



ISOEnts.zip can simply be unzipped into the directory where the DocBook DTD
is unzipped without requiring anything else but the files in isoENT-tar.gz
are also needed. Again, the files in isoENT-tar.gz are to be unzipped into
the DocBook DTD directory (see next section on installing for details), but
the filenames end with ".ent" suffix. These will need to be renamed to a
".gml" ending. You can do this manually, or you can download and use the file
below, made by this author, which contains the files of both ISOEnts.zip and
isoENT-tar.gz:

[http://www.comptechnews.com/~reaster/iso8879-entities.tar.gz] http://
www.comptechnews.com/~reaster/iso8879-entities.tar.gz
-----------------------------------------------------------------------------

2.4. DocBook DSSSL

The Document Style Semantics and Specification Language (DSSSL) files for the
DocBook DTD (SGML/XML) is provided by [http://www.nwalsh.com/] Norm Walsh.
These files, called the [http://nwalsh.com/docbook/dsssl/] Modular DocBook
Stylesheets, tell openjade what to do when converting your DocBook SGML file
into other formats. A dsl file specifies things such as the mappings from one
DTD's tags to another DTD's tags and other programmatic conversions,
programmed in a language called the [http://www.nwalsh.com/] Core Expression
Language which is derived from [http://www.gnu.org/manual/elisp-manual-20-2.5
/html_chapter/elisp_2.html#SEC5] Scheme. The DocBook DSSSL package and
documentation can be downloaded from Norm Walsh:

[http://nwalsh.com/docbook/dsssl/] http://nwalsh.com/docbook/dsssl/

The [http://www.linuxdoc.org/] Linux Documentation Project has a stylesheet
customization file that turns on some nice style features. It can be
downloaded at:

[http://www.linuxdoc.org/authors/tools/ldp.dsl] http://www.linuxdoc.org/
authors/tools/ldp.dsl
-----------------------------------------------------------------------------

2.5. Sgmltools-lite

Sgmltools is a frontend for openjade, jadetex, pdfjadex, dvips, and other
programs. It provides a single command for generating all the formats
possible with these tools. The lastest release, v1.3 as of writing, can be
downloaded at:

[http://www.sgmltools.org/] http://www.sgmltools.org/

[http://sourceforge.net/projects/sgmltools-lite/] http://sourceforge.net/
projects/sgmltools-lite/

This package is optional, but does make things easier sometimes.
-----------------------------------------------------------------------------

2.6. HTMLdoc

Htmldoc is a free program for converting websites into Portable Document
Format (pdf) or Postscript (ps). For pdf, it creates a tree of bookmarks that
make navigation easy. Both htmldoc and pdfjadetex output pdf files, but in
slightly different formats. Try both and see which turns out best for a
particular docbook file. See quick links below for download site.
-----------------------------------------------------------------------------

2.7. DocBook2X

DocBook2X requires perl5 and the SGMLS.pm perl module, available at CPAN.
SGMLS.pm provides libraries and a program called sgmlspl which translates
DocBook files into other formats by using specification files. The
specification files are perl files that provide the logic for the translation
to a particular format.

-----------------------------------------------------------------------------

3. Install the Packages

3.1. Install OpenJade

3.1.1. openjade

Here is what to do, but remember to read the files that come with OpenJade to
see if there are any things you want to do special for your platform:
               cd /usr/local
               tar -xvzf ~/openjade-1.3.tar.gz
               cd openjade-1.3
               ./configure --prefix=/usr/local/openjade-1.3
               make
               make install

               # Once installed, the objects etc. can be deleted.
               make clean

The installation puts libraries in /usr/local/openjade-1.3/lib, so you might
like to add it to /etc/ld.so.conf and run ldconfig. Add /usr/local/
openjade-1.3/bin to your $PATH.
-----------------------------------------------------------------------------

3.1.2. jadetex & pdfjadetex

As mentioned, jadetex and pdfjadetex are TeX macros that are packaged with
OpenJade. They can be found in /usr/local/openjade-3.1/dsssl. A handy guide
to installing these macros was prepared by Frank Atanassow Christoph and can
be found at:

[ftp://ftp.dante.de/tex-archive/macros/jadetex/install.pdf] ftp://
ftp.dante.de/tex-archive/macros/jadetex/install.pdf

[http://www.comptechnews.com/~reaster/installjadetex.pdf] http://
www.comptechnews.com/~reaster/installjadetex.pdf

The following, is based on the instructions in install.pdf:
-----------------------------------------------------------------------------

3.1.2.1. Create hugelatex (if needed)

The jadetex and pdfjadetex tex macros require more memory than a regular run
of tex. The default tex memory limit configuration is often too limited. The
tex configuration file, texmf.cnf, can be edited and variables which limit
tex's memory use can be increased. But rather than just editing the texmf.cnf
file to allow tex in all instances to have more memory, a custom tex context
can be created, called hugelatex. If hugelatex is already configured on your
system, you can skip this subsection (which hugelatex).

Verify that a working TeX is installed and find its directory:
               bash$ which tex
               /usr/share/texmf/bin/tex
               bash$ kpsewhich -expand-var='$TEXMFMAIN'
               /usr/share/texmf
               bash$


Using which should find the location of the tex program. If its not found,
then you might need to install teTeX then return here. kpsewhich is a utility
that comes with teTeX and finds the main tex directory if all goes well.

Now that the texmf directory is known, installation can begin:
               cd /usr/share/texmf
               cd tex/latex
               cp -r config config-temp
               cd config-temp
               tex -ini -progname=hugelatex latex.ini
               mv latex.fmt hugelatex.fmt
               mv hugelatex.fmt /usr/share/texmf/web2c
               cd ..
               rm -r config-temp
               cd /usr/share/texmf/bin
               ln -s tex hugelatex
               cd /usr/share/texmf/web2c

The web2c directory contains the texmf.cnf configuration file. Make a backup
of this file: cp texmf.cnf texmf.cnf.orig. Edit the file using whatever
editor you like, and add the following lines at the end:
               % hugelatex settings
               extra_mem_top.hugelatex = 8000000
               extra_mem_bot.hugelatex = 8000000
               hash_extra.hugelatex = 15000
               pool_size.hugelatex = 5000000
               string_vacancies.hugelatex = 45000
               max_strings.hugelatex = 55000
               pool_free.hugelatex = 47500
               nest_size.hugelatex = 500
               param_size.hugelatex = 1500
               save_size.hugelatex = 5000
               stack_size.hugelatex = 15000

               % jadetex
               extra_mem_top.jadetex = 8000000
               extra_mem_bot.jadetex = 8000000
               hash_extra.jadetex = 20000
               pool_size.jadetex = 5000000
               string_vacancies.jadetex = 45000
               max_strings.jadetex = 55000
               pool_free.jadetex = 47500
               nest_size.jadetex = 500
               param_size.jadetex = 1500
               save_size.jadetex = 5000
               stack_size.jadetex = 15000

               % pdfjadetex
               extra_mem_top.pdfjadetex = 8000000
               extra_mem_bot.pdfjadetex = 8000000
               hash_extra.pdfjadetex = 20000
               pool_size.pdfjadetex = 5000000
               string_vacancies.pdfjadetex = 45000
               max_strings.pdfjadetex = 55000
               pool_free.pdfjadetex = 47500
               nest_size.pdfjadetex = 500
               param_size.pdfjadetex = 1500
               save_size.pdfjadetex = 5000
               stack_size.pdfjadetex = 15000

Here, we've gone ahead and added entries for jadetex and pdfjadetex, which
we'll be setting up below. You can play with these memory settings any way
you like if you experience trouble with them.

After setting up hugelatex, like above, it may not work until the texhash
program is called:
               root# texhash
               texhash: Updating /usr/share/texmf/ls-R...
               texhash: Updating /var/cache/fonts/ls-R...
               texhash: Done.
               root#

-----------------------------------------------------------------------------

3.1.2.2. jadetex & pdfjadetex

Setting up jadetex and pdfjadetex is similar to hugelatex.
               cd /usr/local/openjade-1.3/dsssl
               make -f Makefile.jadetex install
               # make creates and installs the .fmt
               # files to /usr/share/texmf/web2c

               # Now create symlinks ...
               cd /usr/share/texmf/bin
               ln -s tex jadetex
               ln -s tex pdfjadetex

               # Finally, run texhash.
               root# texhash

This Makefile uses hugelatex, so hugelatex must have been setup already. When
tex is run as hugelatex, jadetex, or pdfjadetex, it gets its program name
(context) from argv[0] in the environment. Then, it scans texmf.cnf, and uses
any context-specific settings it finds. The format (.fmt) files in /usr/share
/texmf/web2c are also loaded based on the context.

Jadetex takes a tex file generated from openjade, and outputs a dvi.
pdfjadetex takes a tex file generated from openjade, and outputs a pdf. The
dvips program takes the dvi and outputs a postscript ps file.
-----------------------------------------------------------------------------

3.2. DocBook SGML DTD

3.2.1. Unpack the DocBook SGML DTD

The DocBook DTD is just some sgml text files, so there is nothing to compile.
Just unzip them somewhere:
               # DocBook DTD V4.1 in
               # /usr/local/share/sgml/docbook/4.1

               cd /usr/local/share
               mkdir sgml; cd sgml
               mkdir docbook; cd docbook
               mkdir 4.1; cd 4.1
               unzip -a ~/docbk41.zip

If you install doctools-1.2 from the XFree86 distribution, it will put some
older versions of DocBook DTD, like 2.4.1/ and 3.0/ in subdirectories of
docbook.

There are some differences between the different versions of the DocBook DTD.
The xxissues.txt files document those issues. Tags have been added, removed,
and renamed between the versions.

If you need to use DocBook DTD V3.1, it is available from the same place
where V4.1 is downloaded. V3.1 is used a lot, so its a good idea to get it
and install it in a 3.1/ subdirectory.
-----------------------------------------------------------------------------

3.2.2. Unpack the ISO8879 Entities

For each DocBook DTD version unpacked, go into its directory and unpack the
iso8879-entities.tar.gz file:
               cd /usr/local/share/sgml/docbook/4.1
               tar -xvzf ~/iso8879-entities.tar.gz

In each DocBook directory, there should be a docbook.cat file or a catalog
file, or both. If both are present, they are likely to be identical. If only
docbook.cat is present, go ahead and make a symlink:
               # If needed ...
               cd /usr/local/share/sgml/docbook/4.1
               ln -s docbook.cat catalog

-----------------------------------------------------------------------------

3.3. DocBook DSSSL

Installation of the DocBook DSSSL, which works for all versions of DocBook,
is just a matter of unzipping it somwhere.
               cd /usr/local/share/sgml
               mkdir dsssl; cd dsssl
               unzip -a ~/db160.zip

               # If you downloaded the ldp.dsl stylesheet
               # customization, copy it to ...
               cd docbook
               cp ~/ldp.dsl html
               cp ~/ldp.dsl print
               # Copy into both directories.

That's all there is to installing the DSSSL, except for the setup of the
$SGML_CATALOG_PATH discussed later. Don't forget to straighten out the file
modes and owner/group of these unpacked files - often they are scrambled and
inappropriate.
-----------------------------------------------------------------------------

3.4. sgmltools-lite

If you like it, you can install the sgmltools-lite, but it is optional. Its
installation is the standard:
               cd /usr/src
               tar -xvzf ~/sgmltools-lite-3.0.2.tar.gz
               cd sgmltools-lite-3.0.2
               ./configure
               make install

This installs the sgmltools python script to /usr/local/bin. Note that it
uses python, so if you don't have it, then this package is useless.

One tweak that has to be done to make the sgmltools script work, is you have
have to edit it and set the path to openjade: vi `which sgmltools`. Consult
its docs to learn more about it.
-----------------------------------------------------------------------------

3.5. htmldoc

3.5.1. binary

Preferrably you downloaded a binary distribution of htmldoc for your
platform. The installation is straightforward: just unpack it and run the
setup. Read the docs in the package for more info.
-----------------------------------------------------------------------------

3.5.2. source

If you downloaded the source, you will also need the Fast Light Tool Kit or
else it will not link:

[http://www.fltk.org/] http://www.fltk.org/

Installation is autoconf style. Just run the configure script, make, make
install. If all goes well, it will install in /usr/bin.
-----------------------------------------------------------------------------

3.5.3. ldp_print

The htmldoc program has a few glitches when generating output from html files
from openjade. For instance, bullet items are not rendered properly and
shaded areas are not always shaded.

To fix this problem, a perl script ([http://www.linuxdoc.org/authors/tools/
ldp_print.tar.gz] ldp_print) is available from [http://www.linuxdoc.org/]
LinuxDoc.org. The script processes a nochunks html file from openjade and
then runs htmldoc on it to produce correctly rendered pdf and ps.


   Tip: Get it!

               tar -xvzf ldp_print.tar.gz
               cd ldp_print
               cp fix_print_html.lib /usr/lib/perl5/site_perl

               # Copy the lib somewhere where perl looks
               cp ldp_print /usr/local/bin

Take a look at the script in case there are lines in it you need to change
for your system. Perhaps someday htmldoc's bugs will be fixed and this script
will not be needed anymore.
-----------------------------------------------------------------------------

3.6. DocBook2X and SGMLS.pm (sgmlspl)

3.6.1. sgmlspl

Before the spec files from DocBook2X are of any use, the SGMLS.pm module for
perl5 has to be installed, assuming that perl5 is installed. The installation
of this module is not as automated as most perl module installs. It uses a
Makefile that has to be edited first before running make.
               cd /usr/src
               tar -xvzf ~/SGMLSpm-1.03ii.tar.gz
               cd SGMLSpm

               # Edit Makfile
               vi Makefile
               # In the user options of the Makefile
               # set everything correct for
               # your system.
               # Example:
               #       PERL = /usr/bin/perl

3.6.2. docbook2X (docbook2man-spec.pl)

DocBook2X contains no program to compile or install, though it has some
scripts you might want to look at, so all there is to do is unpack it
somwhere.
               cd /usr/local/share/sgml
               tar -xvzf ~/docbook2X-0.6.0.tar.gz
               cd docbook2X

In the unpacked directory is the docbook2man-spec.pl and a patch file for it
that corrects a few things. Applying the patch is optional but recommended.
               patch docbook2man-spec.pl docbook2man-spec.pl.patch

Later, in Using DocBook, you will see how to use sgmlspl and
docbook2man-spec.pl to generate a manpage from a refentry docbook document.
-----------------------------------------------------------------------------

3.7. $SGML_CATALOG_FILES

The $SGML_CATALOG_FILES environment variable is used by openjade (and other
SGML software) to locate DTDs and DSL (stylesheets). SGML software cannot
function without finding these files, which have been unpacked to various
directories. Given the setup as done so far, here is how $SGML_CATALOG_FILES
can be set in /etc/profile:

4. Using DocBook

Now that everything is installed, it's time to test it out and see how to use
openjade and the other tools.

The warnings about DTDDECL can be ignored. They might be a little annoying,
but these warnings are normal when using jade. Other warnings and errors
should be looked at and often indicate syntax errors that you should fix.

Two htm files are generated, one for each <SECT1>. The filenames are not very
descriptive. Section one appears on the same page as the article information.
These are the results of using the default stylesheet that comes with the
Modular DocBook Stylesheets, docbook.dsl.

Stylesheets can be customized to improve on these defaults. If you downloaded
the [http://www.linuxdoc.org/] Linux Documentation Project's ldp.dsl file and
installed it as shown in Section 3.3, then you already have a customized
style available.
-----------------------------------------------------------------------------

4.1.2. ldp.dsl

Figure 3. Generating HTML output using ldp.dsl
bash$ openjade -t sgml -d $SGML_SHARE/dsssl/docbook/html/ldp.dsl#html test.sgml
bash$ ls -l
total 16
-rw-r--r--   1 reaster  users        2006 Dec 31 18:00 index.html
-rw-r--r--   1 reaster  users        1077 Dec 31 16:25 test.sgml
-rw-r--r--   1 reaster  users        1677 Dec 31 18:00 test1.html
-rw-r--r--   1 reaster  users        1598 Dec 31 18:00 test2.html
bash$


Using ldp.dsl, the output looks better:

��*�An index file has been created that contains the article information.

��*�A table of contents has been automatically generated.

��*�Each <SECT1> is in its own file.

��*�Filenames are derived from ID attributes of the <SECT1> elements.

��*�The file extension has changed to html.

��*�The <SCREEN> elements are shaded.


Note how the ldp.dsl file is written in the command line: it has "#html"
appended. Ldp.dsl contains two <STYLE-SPECIFICATION> elements, one with ID=
"html" and another with ID="print". This selects the html style from within
ldp.dsl. The DocBook DSSSL contains support for converting DocBook files into
html and print formats. In Section 3.3, we copied ldp.dsl into both the print
and html directories. When generating html output, the html style should be
selected like above. When generating other types of files, such as rtf and
tex, they fall under the print style and so the print style should be
selected from ldp.dsl. The alternative is to comment out or delete the print
or html style in the copy of ldp.dsl in the respective directory. If a dsl
file has more than one style-spec in it and none is selected like in the
example above, then the first style encountered in the file is selected. For
ldp.dsl, the print style-spec is first in the file, so it gets selected by
default. So in the example above, without appending "#html" when specifying
ldp.dsl as the dsssl stylesheet, the "print" style-spec would be selected and
used when generating the html output. It will work, but is intended for when
selecting the "print/ldp.dsl" and the formatting will be different.

To learn more about how the stylesheet customization files are made, read the
[http://nwalsh.com/docbook/dsssl/doc/] documentation for the Modular DocBook
Stylesheets. Customization mainly involves setting boolean option parameters
to toggle style features on and off. Completely new style logic can be
programmed using DSSSL's [http://www.mulberrytech.com/dsssl/dsssldoc/
tutorials/core-exp/core-exp.html] Core Programming Language, as mentioned in
Section 2.4.

The openjade option "-t output_type" specifies the output type. The "-d
dsssl_spec" option is the path to the dsssl stylesheet to use. In the example
above, the output type specified is sgml, which is for SGML to SGML
transformations. HTML, defined by the [http://www.w3.org/TR/html4/sgml/
dtd.html] HTML Document Type Definition (DTD), is an SGML document type just
as DocBook is, so "sgml" is the correct output_type option. The other two
output types commonly used are "rtf" and "tex". The tex output_type will be
used later as an intermediate format for the generation of pdf and ps
formats. The dsssl_spec must specify a dsl file, not a directory.

Usage is just like for most projects:


Figure 10. Invoking make to run Makefile
               -- generate html (default)
               make
               -- generate just pdf
               make pdf
               -- generate all files
               make all
               -- delete all generated files
               make clean
               -- create tgz distribution
               -- with no generated files
               make dist
               -- create tgz distribution
               -- containing all generated files
               make distall


Notice the commented compile rules for pdf and ps which provide alternative
means of generating those files.

4.6. Generating a manpage

During the section on installing everything, we installed the perl5 module
SGMLSpm. Then we installed docbook2X which provides the spec.pl files for
transforming DocBook RefEntry documents into nroff (manpage) format with
sgmlspl.

An example Docbook RefEntry document, for the foo command, is given below.

NAME
      foo - Does nothing useful.

SYNOPSIS
      foo [ -f bar ]  [ -dn ]  [ file... ]

DESCRIPTION
      foo does nothing useful.

OPTIONS
      -f bar Takes  bar as its run control file. If this were a
             real program, there might be more to say here about
             what bar is and how it will be used.

      -dn    Do  something,  where  integer n specifies how many
             times.

      file...
             Processes the files in the  order  listed,  sending
             all output to stdout.

USAGE
      foo -f foo.conf -d2 foodata.foo

CAVEATS
      Other  programs  named foo may exist and actually do some-
      thing!

BUGS
      None. Program does nothing.

AUTHOR
      Foo E Bar (Original author)

[snip - several extra blank lines that man would not show]
foo 1.0                     2001-01-01                          1
bash$ groff -mandoc -Tascii foo.1 | less
bash$ less foo.1


The manpage, foo.1, is generated as a Section 1 page. The groff command is
used to give a quick look at its formatted appearance.

To install this manpage, it belongs in any man/man1 directory, where the
directory man/ is added to $MANPATH in the environment. The standard location
is /usr/local/man/man1. The standard sections in the manpages system are 1
though 9. Each is for holding specific catagories of documentation.


Table 1. Manpage Sections
+-------+----------------------------------------+
|Section|                Purpose                 |
+-------+----------------------------------------+
| man1  |             User programs              |
+-------+----------------------------------------+
| man2  |              System calls              |
+-------+----------------------------------------+
| man3  |   Library functions and subroutines    |
+-------+----------------------------------------+
| man4  |                Devices                 |
+-------+----------------------------------------+
| man5  |              File formats              |
+-------+----------------------------------------+
| man6  |                 Games                  |
+-------+----------------------------------------+
| man7  |             Miscellaneous              |
+-------+----------------------------------------+
| man8  |         System administration          |
+-------+----------------------------------------+
| man9  |Kernel internal variables and functions |
+-------+----------------------------------------+


   Tip: The source file for a manpage, like foo-ref.sgml, can be processed
   into all the other formats just like any other DocBook file. So using the
   same commands discussed earlier to generate html and print output types,
   a manpage can be made into html and rtf, tex, pdf, dvi, and ps. This can
   really save a lot of conversion work!

Have fun!
