/**

Loads localized versions of template files. If the caller requests a file with the
|
|
name "index" and the suffix is ".tpl" and the requested locale is "de_DE, de, en-US",
|
|
then files are searched in the following order:
|

|
|
- index-de_DE.tpl
|
|
- index-de.tpl
|
|
- index-en_US.tpl
|
|
- index-en.tpl

|
<code><pre>
|
|
path=../templates
|
|
suffix=.tpl
|
|
encoding=UTF-8
|
|
</pre></code>
|
|
The path is relative to the directory of the config file. In case of windows, if the
|
|
settings are in the registry, the path is relative to the current working directory.
