function Set-TiPSConfiguration
{
<#
    .SYNOPSIS
    Set the tiPS configuration.
 
    .DESCRIPTION
    Set the entire or partial tiPS configuration.
 
    .PARAMETER Configuration
    The tiPS configuration object to set.
    All configuration properties are updated to match the provided object.
    No other properties may be provided when this parameter is used.
 
    .PARAMETER AutomaticallyUpdateModule
    Whether to automatically update the tiPS module at session startup.
    The module update is performed in a background job, so it does not block the PowerShell session from starting.
    This also means that the new module version will not be used until the next time the module is imported, or
    the next time a PowerShell session is started.
    Old versions of the module are automatically deleted after a successful update.
    Valid values are Never, Daily, Weekly, Monthly, and Yearly. Default is Never.
 
    .PARAMETER AutomaticallyWritePowerShellTip
    Whether to automatically write a PowerShell tip at session startup.
    Valid values are Never, Daily, Weekly, Monthly, and Yearly. Default is Never.
 
    .INPUTS
    You can pipe a [tiPS.Configuration] object containing the tiPS configuration to set, or
    a PsCustomObject with AutomaticallyUpdateModule and/or AutomaticallyWritePowerShellTip properties.
 
    .OUTPUTS
    None. The function does not return any objects.
 
    .EXAMPLE
    Set-TiPSConfiguration -Configuration $config
 
    Set the tiPS configuration.
 
    .EXAMPLE
    Set-TiPSConfiguration -AutomaticallyUpdateModule Weekly
 
    Set the tiPS configuration to automatically update the tiPS module every 7 days.
 
    .EXAMPLE
    Set-TiPSConfiguration -AutomaticallyWritePowerShellTip Daily
 
    Set the tiPS configuration to automatically write a PowerShell tip every day.
 
    .EXAMPLE
    Set-TiPSConfiguration -AutomaticallyUpdateModule Never -AutomaticallyWritePowerShellTip Never
 
    Set the tiPS configuration to never automatically update the tiPS module or write a PowerShell tip.
