Welder User Manual
Since Plesk is a web application, a single instance may simultaneously target an 
international, multi-language audience owing to the possibility of localization. 
Localization means a process of adapting software for a particular country or region, 
which is, generally speaking, translating Plesk user's environment to a language 
spoken in the country or region. 
A subset of Plesk user's environment adjusted to a particular language and culture is 
called locale. The Locale Components (on page 8) section answers what substitutes a 
Plesk locale. 
On the implementation level, a particular locale is represented by the corresponding 
language pack (LP). Language pack is an installable file containing all the resource 
files and processing instructions necessary for installing a particular locale to an 
existing Plesk instance. In other words, LP is a packed set of files containing all the 
language-related data that define the appearance of a particular user environment 
component. The Language Pack Content (on page 9) section focuses on what files are 
included to an LP, how the files must be structured, and shows how these files are 
related to locale components. 
Plesk locale and language pack names follow the RFC 1766 standard in the format 
"<languagecode2>-<country/regioncode2>", where <languagecode2> is a lower-case 
two-letter code derived from ISO 639-1 and <country/regioncode2> is an upper-case 
two-letter code derived from ISO 3166. For example, U.S. English locale is named "en-
US". To see a list of locale names supported by Plesk, refer to the Appendix Locale 
Codes (on page 20). 
Note: Plesk supports an arbitrary number of locales (depends on the purchased Plesk 
license). A particular locale can be represented by only one LP, that is, you cannot 
install to a Plesk, for example, two different en-US language packs. 
By default, Plesk is shipped with only U.S. English language pack. Parallels also 
releases LP's for eight additional languages, which are: 
  German (de-DE) 
  French (fr-FR) 
  Spanish (es-ES) 
  Italian (it-IT) 
  Russian (ru-RU) 
  Japanese (ja-JP) 
  Simplified Chinese (zh-CN) 
  Traditional Chinese (zh-TW)
