+
+*Утилита командной строки для манипулирования ini файлами с дублирующимися именами ключей.*
+
+Скомпилированная версия multini доступна на [странице релизов](https://github.com/GenZmeY/multini/releases).
+
+***
+
+# Описание
+Некоторые программы используют формат ini файлов допускающий повторяющиеся имена ключей.  
+Например игры основаные на [unreal engine](https://en.wikipedia.org/wiki/Unreal_Engine).  
+Это может выглядеть так (часть конфигурации Killing Floor 2):
+```
+[OnlineSubsystemSteamworks.KFWorkshopSteamworks]
+ServerSubscribedWorkshopItems=2267561023
+ServerSubscribedWorkshopItems=2085786712
+ServerSubscribedWorkshopItems=2222630586
+ServerSubscribedWorkshopItems=2146677560
+```
+Большинство реализаций поддерживают только одно свойство с заданным именем в секции. Если их несколько, будет обрабатываться только первый (или последний) ключ, чего в данном случае недостаточно. multini решает эту проблему.
+
+**примечание:**  
+- multini чувствителен к регистру;  
+- кавычки вокруг значения не обрабатываются (multini считает их частью значения);  
+- многострочные значения не поддерживаются.  
+(но все это может измениться в будущем)  
+
+# Сборка и установка (вручную)
+1. Установите [golang](https://golang.org), [git](https://git-scm.com/), [make](https://www.gnu.org/software/make/);
+2. Клонируйте этот репозиторий: `git clone https://github.com/GenZmeY/multini`
+3. Перейдите в каталог с исходниками: `cd multini`
+4. Выполните сборку: `make`
+5. Выполните установку: `make install`
+
+# Использование
+```
+Использование: multini [ПАРАМЕТРЫ]... ДЕЙСТВИЕ ini_file [секция] [ключ] [значение]
+Действия:
+  -g, --get          Получить значения для заданной комбинации параметров.
+  -s, --set          Установить значения для заданной комбинации параметров.
+  -a, --add          Добавить значения для заданной комбинации параметров.
+  -d, --del          Удалить указанную комбинацию параметров.
+  -c, --chk          Показать ошибки парсинга указанного файла.
+
+Параметры:
+  -e, --existing     Для --set и --del завершить программу с ошибкой, если элемент остутствует.
+  -r, --reverse      Для --add добавлять элемент в начало секции
+  -i, --inplace      Перезаписывать исходный файл.
+                     Это не атомарно, но требует меньше разрешений
+                     чем способ по умолчанию с заменой файла.
+  -o, --output ФАЙЛ  Записать результат в ФАЙЛ. '-' означает стандартный вывод
+  -u, --unix         Использовать LF в конце строки
+  -w, --windows      Использовать CRLF в конце строки
+  -q, --quiet        Подавить весь вывод
+  -h, --help         Отобразить страницу помощи
+      --version      Отобразить версию
+```
+
+# Примеры
+**вывести глобальное значение вне секции:**  
+`multini --get ini_file '' key`
+
+**вывести секцию:**  
+`multini --get ini_file section`
+
+**вывести список секций:**  
+`multini --get ini_file`
+
+**вывести значение:**  
+`multini --get ini_file section key`  
+- если ключей несколько, отобразится список всех значений этих ключей
+
+**создать/обновить ключ (в единственном экземпляре):**  
+`multini --set ini_file section key value`  
+- если ключа нет, он будет добавлен  
+- если ключ существует, значение будет обновлено  
+- если ключ существует и имеет несколько значений, будет установлен ключ с указанным значением, остальные значения будут удалены
+
+**добавить ключ с указанным значением:**  
+`multini --add ini_file section key value`  
+- если ключа нет, он будет добавлен
+- если ключ существует и не имеет указанного значения, будет добавлено новое значение
+- если указанное значение повторяет существующее, никаких изменений не будет
+
+**удалить все ключи с указанным именем:**  
+`multini --del ini_file section key`
+
+**удалить ключ с указанным именем и значением:**  
+`multini --del ini_file section key value`
+
+**удалить секцию:**  
+`multini --del ini_file section`
+
+**короткие версии параметров можно комбинировать:**  
+`multini -gq ini_file section key value`  
+- проверить наличие ключа с заданным значением, используя код возврата

+
+*Command line utility for manipulating ini files with duplicate key names.*
+
+A compiled version of multini is available on the [release page](https://github.com/GenZmeY/multini/releases).
+
+***
+
+# Description
+Some programs use ini file format with duplicate key names.  
+For example, these are games based on the [unreal engine](https://en.wikipedia.org/wiki/Unreal_Engine).  
+It might look like this (part of the Killing Floor 2 config):  
+```
+[OnlineSubsystemSteamworks.KFWorkshopSteamworks]
+ServerSubscribedWorkshopItems=2267561023
+ServerSubscribedWorkshopItems=2085786712
+ServerSubscribedWorkshopItems=2222630586
+ServerSubscribedWorkshopItems=2146677560
+```
+Most implementations only support having one property with a given name in a section. If there are several of them, only the first (or last) key will be processed, which is not enough in this case. multini solves this problem.
+
+**note:**  
+- multini is case sensitive;
+- quotes around the value are not processed (they are part of the value for multini);  
+- multi-line values are not supported.  
+(but this may change in the future)  
+
+# Build & Install (Manual)
+1. Install [golang](https://golang.org), [git](https://git-scm.com/), [make](https://www.gnu.org/software/make/);
+2. Clone this repo: `git clone https://github.com/GenZmeY/multini`
+3. Go to the source directory: `cd multini`
+4. Build: `make`
+5. Install: `make install`
+
+# Usage
+```
+Usage: multini [OPTION]... ACTION ini_file [section] [key] [value]
+Actions:
+  -g, --get          Get values for a given combination of parameters.
+  -s, --set          Set values for a given combination of parameters.
+  -a, --add          Add values for a given combination of parameters.
+  -d, --del          Delete the given combination of parameters.
+  -c, --chk          Display parsing errors for the specified file.
+
+Options:
+  -e, --existing     For --set and --del, fail if item is missing.
+  -r, --reverse      For --add, adds an item to the top of the section
+  -i, --inplace      Lock and write files in place.
+                     This is not atomic but has less restrictions
+                     than the default replacement method.
+  -o, --output FILE  Write output to FILE instead. '-' means stdout
+  -u, --unix         Use LF as end of line
+  -w, --windows      Use CRLF as end of line
+  -q, --quiet        Suppress all normal output
+  -h, --help         Write this help to stdout
+      --version      Write version to stdout
+```
+
+# Examples
+**output a global value not in a section:**  
+`multini --get ini_file '' key`
+
+**output section:**  
+`multini --get ini_file section`
+
+**output list of existing sections:**  
+`multini --get ini_file`
+
+**output value:**  
+`multini --get ini_file section key`  
+- if there are several keys, a list of all values of this keys will be displayed
+
+**create/update a single key:**  
+`multini --set ini_file section key value`  
+- if there is no key, it will be added  
+- if the key exists, the value will be updated  
+- if the key exists and has several values, the key with the specified value will be set, the rest of the values will be deleted
+
+**add a key with specified value:**  
+`multini --add ini_file section key value`  
+- if there is no key, it will be added  
+- if the key exists and does not have the specified value, the new value will be added  
+- if the specified value repeats the existing one, no changes will be made
+
+**delete all keys with specified name:**  
+`multini --del ini_file section key`
+
+**delete a key with specified name and value:**  
+`multini --del ini_file section key value`
+
