.SYNOPSIS
    Загрузка изменений из Git в базу 1С

.DESCRIPTION
    Определяет изменённые файлы конфигурации по данным Git и выполняет
    частичную загрузку в информационную базу.

.PARAMETER V8Path
    Путь к каталогу bin платформы или к 1cv8.exe

.PARAMETER InfoBasePath
    Путь к файловой информационной базе

.PARAMETER InfoBaseServer
    Сервер 1С (для серверной базы)

.PARAMETER InfoBaseRef
    Имя базы на сервере

.PARAMETER UserName
    Имя пользователя 1С

.PARAMETER Password
    Пароль пользователя

.PARAMETER ConfigDir
    Каталог XML-выгрузки конфигурации (git-репозиторий)

.PARAMETER Source
    Источник изменений: All, Staged, Unstaged, Commit (по умолчанию All)

.PARAMETER CommitRange
    Диапазон коммитов (для Source=Commit), напр. HEAD~3..HEAD

.PARAMETER Extension
    Имя расширения для загрузки

.PARAMETER AllExtensions
    Загрузить все расширения

.PARAMETER Format
    Формат файлов: Hierarchical или Plain (по умолчанию Hierarchical)

.PARAMETER DryRun
    Только показать что будет загружено (без загрузки)

.EXAMPLE
    .\db-load-git.ps1 -InfoBasePath "C:\Bases\MyDB" -ConfigDir "C:\src" -Source All

.EXAMPLE
    .\db-load-git.ps1 -InfoBasePath "C:\Bases\MyDB" -ConfigDir "C:\src" -Source Commit -CommitRange "HEAD~3..HEAD"

.EXAMPLE
    .\db-load-git.ps1 -InfoBasePath "C:\Bases\MyDB" -ConfigDir "C:\src" -DryRun
