+===== Bulk User Import =====
+
+Requires a CSV file of users with at least four columns.
+The columns must contain, in order: user-id, full name, email address and groups.
+The CSV fields should be separated by commas (,) and strings delimited by quotation marks ("").  Backslash (\) can be used for escaping.
+For an example of a suitable file, try the "Export Users" function above.  
+Duplicate user-ids will be ignored.
+
+A password will be generated and emailed to each successfully imported user.

+===== Импорт нескольких пользователей =====
+
+Потребуется список пользователей в файле формата CSV, состоящий из 4 столбцов. 
+Столбцы должны быть заполнены следующим образом: user-id, полное имя, эл. почта, группы.
+Поля CSV должны быть отделены запятой (,), а строки должны быть заключены в кавычки (""). Обратный слэш используется как прерывание.
+В качестве примера можете взять список пользователей, экспортированный через «Экспорт пользователей».
+Повторяющиеся идентификаторы user-id будут игнорироваться.
+
+Пароль доступа будет сгенерирован и отправлен по почте удачно импортированному пользователю.

+Vyžaduje CSV súbor používateľov s minimálne 4 stĺpcami.
+Stĺpce musia obsahovať postupne: ID používateľa, meno a priezvisko, emailová adresa a skupiny.
+CVS záznamy by mali byť oddelené čiarkou (,) a reťazce uzavreté úvodzovkami (""). Znak (\) sa používa v spojení so špeciálnymi znakmi.
+Príklad vhodného súboru je možné získať funkciou "Export používateľov".
+Duplicitné ID používateľov budú ignorované.
+
+Každému úspešne importovanému používateľovi bude vygenerované heslo a zaslaný email.
