`<TMPL_IF variable>text</TMPL_IF>`.
* To use one block of text if a variable is set and a second if it's not,
use `<TMPL_IF variable>text<TMPL_ELSE>other text</TMPL_IF>`
* Each template file included in the wiki's source will also generate a regular
wiki page. In many cases you might want to prevent some of your template
being interpreted for the regular page. Use the [[if]] directive with the
`included()` test to guard the template code.
Here's a sample template:
<span class="infobox">
Name: \[[<TMPL_VAR raw_name>]]<br />
Age: <TMPL_VAR age><br />
<TMPL_IF color>
Favorite color: <TMPL_VAR color><br />
<TMPL_ELSE>
No favorite color.<br />
</TMPL_IF>
<TMPL_IF notes>
<hr />
<TMPL_VAR notes>
</TMPL_IF>
</span>
\[[!if test="included()" then="""
<span class="infobox">
Name: \[[<TMPL_VAR raw_name>]]<br />
Age: <TMPL_VAR age><br />
<TMPL_IF color>
Favorite color: <TMPL_VAR color><br />
<TMPL_ELSE>
No favorite color.<br />
</TMPL_IF>
<TMPL_IF notes>
<hr />
<TMPL_VAR notes>
</TMPL_IF>
</span>
""" else="""
This is a template page.
"""]]
The filled out template will be formatted the same as the rest of the page
that contains it, so you can include WikiLinks and all other forms of wiki
