Converts [PSObjects] into a format suitable for storing in a file, so you can dot-source hashtables.

export-hashtable.ps1

function Export-HashTable {
    param(
        [Parameter(Mandatory, ValueFromPipeline)]
        [Alias('InputObject')]
        [PSObject]$HashTable,
        [String]$Path,
        [String]$Name
    )
    process {
        $divWidth = ($HashTable.Keys.Length | Measure-Object -Maximum).Maximum + 8

        $hashString = ("$(if($Name){"`$$Name = "})@" + ($HashTable | ConvertTo-JSON) -replace '":','"=' -replace '",
','"
').Split("`n") | %{if($_ -match '^(\W+"\w+")=') {
            $_ -replace '^(\W+"\w+")=',"$($Matches[1] + (' '*($divWidth - $Matches[0].Length)))="}
            else {$_}
        }
    }
    end {
        if ($Path) {
            Out-File -FilePath $path -InputObject $hashString -Encoding utf8
        }
        else {
            return $hashString
        }
    }
}

Yes, I'm more than a little aware how insane/awful lines 11-13 are.
