The content of the msg text in the source code is non translatable due to ambiguity.

[xxx] means normally a variable will be inserted here
example: "[Time]" may NOT be translated but "[l]" (for load) should be translated.

<xxx> means normally XML and should not be translated:
example: "<variable id="jan">hello</variable>" may NOT be translated but "-p <file>" should be translated.

$xxx means normally a variable will be inserted here
example: "$id" may NOT be translated but "$100" dollar should be translated.

Now try to explain that to our translators, it is easier to change the source texts !
