+/*
+			----===[[[[ Virtools Language Pack File ]]]]===----
+
+   Rules:
+   First line must contain the string 'Language:' followed by the language name.
+   The file may be seen as sections, each section name is enclosed in brackets ([,])
+   Sections can have sub-sections, with names enclosed in brackets (<,>)
+   For every section or sub-section, you can have as many entries as you want,
+   which can be:	- strings (optionaly enclosed in quotes)
+			- numbers
+   Separators for entries are ',',';' or LF (line feed)
+   Entries belong to the last section or sub-section specified, until
+   a new section is reached. The first entry of the section has an index of 0,
+   the next one, an index of 1, and so on.
+   Comments can be added using the standard ANSI C++ scheme.
+   Also, dont remove %s,%d and %f tags, those will be replaced at runtime by strings or numbers.
+   A string can take multiple lines, adding \ at the end of the line means that the entry
+   continues on the next line.
+
+   NOTE FOR TRANSLATORS: DO NOT CHANGE ENTRIES ORDER IN THIS FILE!!!
