There is a good example in the GT::Template::Tutorial, which shows the great possibilities of the new, improved LSQL v3.0 template system.
<%set Title = 'Login'%>
<%include header.htm%>
and then in your header.htm:
<html>
<head>
<title><%Title%></title>
</head>
This would allow you to have different titles, but still include the same header template on each page.
GT::Template also supports including a file based on the value of a variable by specifying the variable name (starting with a $) for the filename:
<%include $var%>
This allows for more powerful include abilities. For example, if you wanted to have a single outer template which includes another, variable template you could use an outer template (for the purposes of this example, assume this template is named 'outer.html') something like:
<html>
<head><title><%title%></title></head>
<body>
<div style="border: 5px solid black">
<%include $inner_template%>
</div>
</body>
</html>
Then, inside other templates, you would do:
abc.html:
=========
<%set inner_template = 'abc_content.html'%>
<%set title = 'ABC'%>
<%include layout.html%>
xyz.html:
=========
<%set inner_template = 'xyz_content.html'%>
<%set title = 'XYZ'%>
<%include layout.html%>
Now both abc.html and xyz.html would show up with the same page layout defined in layout.html, with a content section coming from their respective *_content.html templates.
It provides almost all features I listed earlier.
Directories - possible with <%include dir/file.html%>, so grouping is greatly possible
Inheritance - already possible since a long time
Variable files - possible to create variable files, where the tags are defined
using <%set tag='sometime'%> then this is included using <%include file.var%>,
then the <%include file.html%> is used, to display a file with changed variables
Skeleton-like template structure - possible using the technology mentioned in above GT::Template::Tutorial, using variable files.
3 important things are still missing from the GT template system:
There would be nice, if GT would provide a template set, which is based on a skeleton-like template set, and provide several color themes of it (using inheritance) to show the possibilities of the GT template system.

Another useful example is in including a common header or footer to all pages. If, for example, you have a header.htm that you wish to be included, but it needs a variable title, you could combine the include with a set, such as: <%set Title = 'Login'%>
<%include header.htm%>
and then in your header.htm:
<html>
<head>
<title><%Title%></title>
</head>
This would allow you to have different titles, but still include the same header template on each page.

3 important things are still missing from the GT template system:
- Site level - missing
- <%include $foo if%> - missing to include based on existance checking of currently used $foo variable
- Multi-line set command - missing?
There would be nice, if GT would provide a template set, which is based on a skeleton-like template set, and provide several color themes of it (using inheritance) to show the possibilities of the GT template system.
