-Filenames of templates are restricted to the regular expression <tt>^[a-z0-9_.]+$</tt> and are case-insensitive.
+Base names of templates are restricted to the regular expression <tt>^[a-z0-9_]+$</tt> and are case-insensitive. They may have an extension (legal values: "od[ts]t", "xtt") and a variant ID (at the moment numeric, but may match "^[a-z0-9_]+$").<p>
+
+Below "file name" refers to the complete concatenation of base name, extension, and variant:
+<i>basename</i><b>.</b><i>extension</i>[<b>,</b><i>variant</i>]
<h3>List of Templates</h3>
<pre>
<TList>
- <Template name="filename" hash="md5-hash"/>
+ <Template name="filename" hash="md5-hash">Description text</Template>
...
</TList>
</pre>
<h3>Setting a Template</h3>
-The <tt>settemplate</tt> transaction creates a new template file. The request contains the file name terminated with a newline ("\n") and then the binary content of the template - it is important that there are no additional characters between the newline and the template content. The response contains the new hash of the template or error details.
\ No newline at end of file
+The <tt>settemplate</tt> transaction creates a new template file. The request contains the file name terminated with a newline ("\n") and then the binary content of the template - it is important that there are no additional characters between the newline and the template content. The response contains the new hash of the template or error details. The description is initially set to NULL and can be changed later with <tt>settemplatedescription</tt>.<p>
+
+The <tt>settemplatedescription</tt> transaction sets a new description for a template. The first line of the request contains the filename, the remainder the description.
+
+<h3>Deleting a Template</h3>
+
+The <tt>deletetemplate</tt> transaction deletes a template from the database. The request contains the file name (full name). The response is empty. The transaction does not return any errors.
