Get-Help expects examples to start with one or more lines of code, followed by a description of the example, for example:

function Get-Something {
    <#
    .SYNOPSIS
        Briefly describes the main action performed by Get-Something
    .DESCRIPTION
        A detailed description of the activities of Get-Something.
    .EXAMPLE
        $something = Get-Something
        $something | Do-Something

        Gets something from somewhere.
    #>

    param (
        # Describes the purpose of Parameter1.
        $Parameter1,

        # Describes the purpose of Parameter2.
        $Parameter2
    )
}

The help parser is quite simple when it comes to comment-based help. Only the very first line of an example is considered to be code. This can be demonstrated by exploring the object returned by Get-Help based on the preceding example:

PS> (Get-Help Get-Something -Examples).examples[0].example.code
$something = Get-Something

The rest of the code is part of the remark. It is only possible to overcome this parsing problem by writing help in MAML.
