<title>Example of code citations and user input</title>
<para>When showing user input, you want a nice sceen-looking layout, a prompt, monospace text, and a way to differentiate input from output. Here's an example:
<para>Docbook also allows for formatting and display of common languages, allowing for whitespace
and line returns just as they are written. Here's a sample snippet of C code with line numbering enabled:<programlisting linenumbering="numbered"><![CDATA[#include<stdio.h>
<para>Maven/docbkx failures generally fall into one of two categories, validation errors or build failures. Correcting the document begins with understanding which type of failure has occurred and understanding where to look in your document source.</para>

<title>Project structure errors</title>
<para>Because the OpenPOWER Foundation documentation projects are not self-contained in the
GitHub repositories, forgetting to clone the <literal>Docs-Master</literal> project in addition
to the document project or cloning it in the wrong location is a common problem. Failures of this kind
produce the following error:</para>

<title>Build failures</title>
<para>Build errors are easily identified as well. Below is an example:

<note><para>Projects may contain multiple documents. While specific documents can be built by executing a
<literal>mvn clean generate-sources</literal> in the specific document directory, executing this command in
the base project directory will build all projects identified in the <literal><module></literal> list in the
top-level <literal>pom.xml</literal> file, known as the "workgroup-pom".</para></note>
<para>To successfully build OpenPOWER Foundation documents, common document files must be in place in addition to the specific
document files. These common files are obtained by cloning the OpenPOWER Foundation public project <literal>Docs-Master</literal>.</para>
<para>To clone the master template document framework use the clone git command:<screen><prompt>$ </prompt><userinput>git clone https://github.com/OpenPOWERFoundation/Docs-Master.git</userinput>

<title>Cloning the base document framework</title>
<para>All new projects need to begin by cloning the appropriate documentation template. The template document project resides at <link xlink:href="https://github.com/open-power/openpower-foundation-docbkx-framework.git">https://github.com/open-power/openpower-foundation-docbkx-framework.git</link>. This template should be used for both private and public OpenPOWER Foundation documents.</para>
<para>To clone the existing template document framework use the clone git command:<screen><prompt>$</prompt><userinput>git clone https://github.com/open-power/openpower-foundation-docbkx-framework.git</userinput>
Cloning into 'openpower-foundation-docbkx-framework'...
<para>This command clones the head of the git tree into your current working directory. If successful, the contents of the current directory should now include a new <literal>openpower-foundation-docbkx-framework</literal> directory.</para>
</section>
<prompt>$ </prompt></screen> The results should look roughly something like above with actual numbers of objects, files, etc. varying

<title>Copying the template directory into a new project directory</title>
<para>To create a new document directory, follow these steps:</para>
<title>Finding a document framework</title>
<para>If this is your first document, in a brand new project (git tree), you have the fewest number of steps
to perform because your project should have been primed with a single project based on <literal>Docs-Template</literal>.
You can verify this by inspecting
the files in your project directory. A new project will contain a <literal>template</literal> directory, a <literal>pom.xml
</literal> file, a <literal>LICENSE</literal> file, and a <literal>README.md</literal> file. If this is the case, you simply
need to perform the following three steps:</para>
<orderedlist>
<listitem>
<para>Navigate down to the <literal>doc</literal> sub-directory. On Linux and Mac OS command lines, this can be achieved using the <literal>cd</literal> command:
<para>This directory should contain at least two directories, one named <literal>doc</literal> and another <literal>template</literal>, as well as a <literal>pom.xml</literal> file.</para>
<listitem>
<para>Navigate down to your project directory, called <literal>my_project</literal> for this example. This can be achieved
<para>This directory should contain the <literal>template</literal> folder used to prime the project.</para>
</listitem>
<listitem>
<para>To create a new project directory, simply create a new directory and copy the contents of the <literal>template</literal> directory. If creating a new project named <literal>my_proj</literal> via a command line in Linux or Mac OS, the command sequence would look like this:
<para>Once copied, the Docs-Template directory and all its contents should be removed from your project so that it does accidentally get
included in your project. The command <userinput>rm -rf Docs-Template</userinput></para>
</listitem>
<listitem>
<para>Finally, add the new project to the workgroup POM.xml file. Using your editor, add the following lines
between the <modules> and the </modules> tags near the top of the file:<programlisting><![CDATA[<module>my_doc</module>
]]></programlisting></para>
</listitem>
</orderedlist>
</section>
<section>
<note><para>Before committing the project back to git, you will need to add the new directory to the git repository. This can
be performed using the <literal>git add my_doc/</literal> command on the whole directory.</para></note>
<warning><para></para></warning>
<para>You are now ready to begin making updates to your new document. The next section will provided detailed steps of where to
get started.</para>
</section>
<section xml:id="section_modifying_project">
<title>Modifying core project files</title>
<para>The first step to customizing a new project is to modify two core project files--<literal>pom.xml</literal> and <literal>bk_main.xml</literal>. Within these two files are XML comment tags that begin "<literal><!-- TODO:</literal>" to identify places which need customization. The surrounding comments will provide guidance on what needs to change and how it may be changed. Simply work through each item, making updates as requested.</para>
<note><para>Be sure to remember two key values you used in the <literal>pom.xml</literal> file, <literal><webhelpDirname></literal> and <literal><pdfFilenameBase></literal>, as these will be used to locate your generated document.</para></note>
<para>When complete, be sure to build your new document using standard maven commands like this:<screen><prompt>$</prompt><userinput>cd openpower-foundation-docbkx-framework/doc/template</userinput>
<para>If all goes well, the new generated pdf should be available in <literal>target/docbkx/webhelp/<webhelpDirname>/<pdfFilenameBase>.pdf</literal>.</para>
<prompt>$ </prompt></screen></para>
<para>If all goes well, the new generated pdf should be available in
<para>For assistance correcting commmon build failures, see <xref linkend="section_template_debug"/>.</para>
<note><para>The permutations of Maven invocations may be combined into one operation where the parameters are specified in the order
in which one wishes to execute them. Thus, the command <literal>mvn clean generate-sources</literal> would accomplish the
same thing as the above sequence of commands.</para></note>

<section>
<title>Adding new content</title>
<para>The starting point for book content is the <literal>bk_main.xml</literal> file (or whatever to which it was renamed in the previous step). Removal and additions of the main chapter files files will be controlled by entries near the end of that file which appear as follows:<programlisting><![CDATA[ <!-- The ch_preface.xml file is required by all documents -->
<xi:include href="../common/ch_preface.xml"/>
