function Write-Log
{
<#
.SYNOPSIS
    Dispatches log information

.DESCRIPTION
    Write log information to the console so that it can be picked up by the deployment system
    The information written to the (host) display uses the following format:

    yyyy-MM-dd HH:mm:ss [Labels[]]<ScriptName>: <Message>

    Where:
    * yyyy-MM-dd HH:mm:ss is the sortable date/time where the log entry occurred
    * [Labels[]] represents one or more of the following colored labels:
        [ERROR]
        [FAILURE]
        [WARNING]
        [INFO]
        [DEBUG]
        [VERBOSE]
        [WHATIF]
        Note that each label could be combined with another label except for the [ERROR] and [FAILURE]
        which are exclusive and the [INFO] label which only set if none of the other labels applies
        (See also the -Warning and -Failure parameter)
    * <ScriptName> represents the script that called this Write-Log cmdlet
    * <Message> is a string representation of the -Object parameter
        Note that if the -Object contains an [ErrorRecord] type, the error label is set and the error
        record is output in a single line:

        at <LineNumber> char:<Offset> <Error Statement> <Error Message>

        Where:
        * <LineNumber> represents the line where the error occurred
        * <Offset> represents the offset in the line where the error occurred
        * <Error Statement> represents the statement that caused the error
        * <error message> represents the description of the error

.PARAMETER Object
    Writes the object as a string to the host from a script or command.
    If the object is of an [ErrorRecord] type, the [ERROR] label will be added and the error
    name and position are written to the host from a script or command unless the $ErrorPreference
    is set to SilentlyContinue.

.PARAMETER Warning
    Writes warning messages to the host from a script or command unless the $WarningPreference
    is set to SilentlyContinue.

.PARAMETER Failure
    Writes failure messages to the host from a script or command unless the $ErrorPreference
    is set to SilentlyContinue.

    Note that the common parameters -Debug and -Verbose have a simular behavor as the -Warning
    and -Failure Parameter and will not be shown if the corresponding $<name>preference variable
    is set to 'SilentlyContinue'.

.PARAMETER Path
    The path to a log file. If set, all the output is also sent to a log file for all the following
    log commands. Use an empty path to stop file logging for the current session: `-Path ''`

    Note that environment variables (as e.g. '%Temp%\My.Log') are expanded.

.PARAMETER Tee
    Logs (displays) the output and also sends it down the pipeline.

.PARAMETER WriteActivity
    By default, the current activity (message) is only exposed (using the Write-Progress cmdlet)
    when it is invoked from the deployment system. This switch (-WriteActivity or -WriteActivity:$False)
    will overrule the default behavior.

.PARAMETER WriteEvent
    When set, this cmdlet will also write the message to the Windows Application EventLog.
    Where:
    * If the [EventSource] parameter is ommited, the Source will be "Automation"
    * The Category represents the concerned labels:
        Info = 0
        Verbose = 1
        Debug = 2
        WhatIf = 4
        Warning = 8
        Failure = 16
        Error = 32
    * The Message is a string representation of the object
    * If [EventId] parameter is ommited, the EventID will be a 32bit hashcode based on the message
    * EventType is "Error" in case of an error or when the -Failure parameter is set,
        otherwise "Warning" if the -Warning parameter is set and "Information" by default.

    Note 1: logging Windows Events, requires elevated rights if the event source does not yet exist.
    Note 2: This parameter is not required if the [EventSource] - or [EventId] parameter is supplied.

.PARAMETER EventSource
    When defined, this cmdlet will also write the message to the given EventSource in the
    Windows Application EventLog. For details see the [WriteEvent] parameter.

.PARAMETER EventId
    When defined, this cmdlet will also write the message Windows Application EventLog using the
    specified EventId. For details see the [WriteEvent] parameter.

.PARAMETER Type
    This parameter will show if the log information is from type INFO, WARNING or Error.
    * Warning: this parameter is depleted, use the corresponding switch as e.g. `-Warning`.

.PARAMETER Message
    This parameter contains the message that wil be shown.
    * Warning: this parameter is depleted, use the `-Object` parameter instead.

.PARAMETER FilePath
    This parameter contains the log file path.
    * Warning: this parameter is depleted, use the `-Path` parameter instead.

.EXAMPLE
    # Log a message

    Displays the following entry and updates the progress activity in the deployment system:

        Write-Log 'Deploying VM'
        2022-08-10 11:56:12 [INFO] MyScript: Deploying VM

.EXAMPLE
    # Log and save a warning

    Displays `File not found` with a `[WARNING]` as shown below, updates the progress activity
    in the deployment system. Besides, it writes the warning to the file: c:\temp\log.txt and
    create and add an entry to the EventLog.

        Write-Log -Warning 'File not found' -Path c:\temp\log.txt -WriteEvent
        2022-08-10 12:03:51 [WARNING] MyScript: File not found

.EXAMPLE
    # Log and capture a message

    Displays `my message` as shown below and capture the message in the `$Log` variable.

        $Log = Write-Log 'My message' -Tee
        2022-08-10 12:03:51 [INFO] MyScript: File not found
