function PSCIEntityFrameworkMigratePackage {

    <#
    .SYNOPSIS
    Deploys one or more Entity Framework migrate packages (using migrate.exe).
 
    .DESCRIPTION
    This function can be invoked both locally (preferred - but SQL Server port will need to be open) and remotely (-RunRemotely - without restrictions but with -RequiredPackages to copy migrate package).
    It uses following tokens:
    - **EntityFrameworkMigratePackages** - hashtable (or array of hashtables) with following keys:
      - **PackageName** - (required) name of Entity Framework package to deploy (the same as in [[Build-EntityFrameworkMigratePackage]])
      - **MigrateAssembly** - (requied) name of the migrations assembly (passed to migrate.exe)
      - **ConnectionString** - (required) connection string that will be used to connect to the destination database (note it will override connection string specified in PublishProfile)
      - **StartupConfigurationFile** - optional startup configuration file (passed to migrate.exe)
      - **PackagePath** - path to the migrate package (If not provided, $PackagePath = $PackagesPath\$PackageName, where $PackagesPath is taken from global variable)
      - **DropDatabase** - if $true, existing database will be dropped before running migrate.exe
       
    See also [[Build-EntityFrameworkMigratePackage]] and [[Deploy-EntityFrameworkMigratePackage]].
 
    .PARAMETER Tokens
    (automatic parameter) Tokens hashtable - see description for details.
 
    .EXAMPLE
    ```
    Import-Module "$PSScriptRoot\..\PSCI\PSCI.psd1" -Force
 
    Build-EntityFrameworkMigratePackage -PackageName 'MyMigration' -MigrationsDir 'Binaries\DataServices' -MigrationsFileWildcard 'MyDataModel.dll' -EntityFrameworkDir 'DataServices\packages\EntityFramework.6.1.3'
 
    # clear any old Environment definitions - required only for -NoConfigFiles deployments
    $Global:Environments = @{}
 
    Environment Local {
        ServerConnection DatabaseServer -Nodes localhost
        ServerRole Database -Steps 'PSCISSDTDacpac' -ServerConnection DatabaseServer
 
        Tokens Database @{
            EntityFrameworkMigratePackages = @{
                PackageName = 'MyDatabase';
                ConnectionString = { $Tokens.Database.ConnectionString }
                MigrateAssembly = 'MyDataModel.dll'
                DropDatabase = $true
            }
        }
 
        Tokens Database @{
            ConnectionString = "Server=localhost\SQLEXPRESS;Database=PSCITest;Integrated Security=SSPI"
        }
    }
 
    try {
        Start-Deployment -Environment Local -NoConfigFiles
    } catch {
        Write-ErrorRecord
    }
 
    ```
    Builds Entity Framework package and deploys it to localhost.
