    .DESCRIPTION
        Bootstrap script for PSDepend.
 
    .PARAMETER DependencyFile
        Specifies the configuration file for the this script. The default value is
        'RequiredModules.psd1' relative to this script's path.
 
    .PARAMETER PSDependTarget
        Path for PSDepend to be bootstrapped and save other dependencies.
        Can also be CurrentUser or AllUsers if you wish to install the modules in
        such scope. The default value is 'output/RequiredModules' relative to
        this script's path.
 
    .PARAMETER Proxy
        Specifies the URI to use for Proxy when attempting to bootstrap
        PackageProvider and PowerShellGet.
 
    .PARAMETER ProxyCredential
        Specifies the credential to contact the Proxy when provided.
 
    .PARAMETER Scope
        Specifies the scope to bootstrap the PackageProvider and PSGet if not available.
        THe default value is 'CurrentUser'.
 
    .PARAMETER Gallery
        Specifies the gallery to use when bootstrapping PackageProvider, PSGet and
        when calling PSDepend (can be overridden in Dependency files). The default
        value is 'PSGallery'.
 
    .PARAMETER GalleryCredential
        Specifies the credentials to use with the Gallery specified above.
 
    .PARAMETER AllowOldPowerShellGetModule
        Allow you to use a locally installed version of PowerShellGet older than
        1.6.0 (not recommended). Default it will install the latest PowerShellGet
        if an older version than 2.0 is detected.
 
    .PARAMETER MinimumPSDependVersion
        Allow you to specify a minimum version fo PSDepend, if you're after specific
        features.
 
    .PARAMETER AllowPrerelease
        Not yet written.
 
    .PARAMETER WithYAML
        Not yet written.
 
    .NOTES
        Load defaults for parameters values from Resolve-Dependency.psd1 if not
        provided as parameter.
