function Deploy-MsDeployPackage {
    <#
    .SYNOPSIS
    Deploys a msdeploy package.
 
    .DESCRIPTION
    Deploys a package created with cmdlet Build-WebPackage or Build-MsBuildPackage.
    If $TokensForConfigFiles is provided, it resolves all token placeholders '${Name}' in all .config files inside the msdeploy package.
    Then it runs msdeploy.exe for the package $PackagePath\$PackageName.zip.
 
    .PARAMETER PackageName
    Name of the package. It determines PackagePath if it's not provided.
 
    .PARAMETER PackageType
    Type of the package - Web or Dir (used e.g. for console application).
 
    .PARAMETER Node
    Server where the package will be deployed to.
 
    .PARAMETER Environment
    Name of the environment where the package will be deployed to. Used for applying XDT transformations by convention (*.<EnvOrNodeName>.config).
 
    .PARAMETER MsDeployDestinationString
    Destination string for msdeploy. Created with cmdlet New-MsDeployDestinationString.
 
    .PARAMETER MsDeployAddParameters
    Additional parameters that will be passed to msdeploy.exe command line.
 
    .PARAMETER PackagePath
    Path to the package containing the msdeploy package. If not provided, $PackagePath = $PackagesPath\$PackageName, where $PackagesPath is taken from global variable.
 
    .PARAMETER TokensForConfigFiles
    A hashtable containing tokens that will be used for replacing placeholders '${Name}' in all .config files inside the msdeploy package.
 
    .PARAMETER ValidateTokensExistence
    If true and a placeholder that not exists in $TokensForConfigFiles table is found, an exception will be thrown.
 
    .PARAMETER SkipDir
    List of directories to skip. Passed in '-skip:Directory' msdeploy parameter.
 
    .PARAMETER SkipFile
    List of files to skip. Passed in '-skip:File' msdeploy parameter.
 
    .PARAMETER UseChecksum
    Whether to use checksum for directory sync. Note checksum sometimes causes issues in msdeploy - see http://stackoverflow.com/questions/20240261/notimplementedexception-in-msdeploy-when-using-usechecksum.
 
    .PARAMETER Website
    IIS website where the package will be deployed to. Only used if PackageType = Web.
 
    .PARAMETER WebApplication
    IIS web application name under which the package will be deployed to. Only used if PackageType = Web.
 
    .PARAMETER PhysicalPath
    Physical path where the package will be copied to. Only used if PackageType = Dir.
    If PackageType = Web, physical path is taken from web application (IIS should be provisioned first).
 
    .PARAMETER FilesToIgnoreTokensExistence
    List of .config files which will not have token placeholders replaced.
    Useful especially if another application uses the same variable placeholder as PSCI (e.g. NLog).
 
    .PARAMETER TokenWildcard
    Wildcard to use to recognize config files where tokens should be replaced.
 
    .PARAMETER TokenRegex
    Regex used to find tokens in the file. Whole tokenRegex should match whole string to replace, first capture group should match name of the token.
 
    .PARAMETER TokenUpdateMode
    Mode of tokens update:
    ReplaceInConfigFiles - traverses all $TokenWildcard (.config) files and replaces $TokenRegex (${var})
    SetParam - passes tokens as -setParam to msdeploy command line.
