Delete all items from SPList - SharePoint 2010 PowerShell

I found this script in the internet, but don't remember where. Therefore I just put it here as is(Of course with all respect points to the anonymous writer of the script) :

[System.Reflection.Assembly]::Load("Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c")

[System.Reflection.Assembly]::Load("Microsoft.SharePoint.Portal, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c")

[System.Reflection.Assembly]::Load("Microsoft.SharePoint.Publishing, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c")

[System.Reflection.Assembly]::Load("System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")

# "Enter the site URL here"

$SITEURL = "http://contoso"

$site = new-object Microsoft.SharePoint.SPSite ( $SITEURL )

$web = $site.OpenWeb()

"Web is : " + $web.Title

# Enter name of the List below

$oList = $web.Lists["MyList"];

"List is :" + $oList.Title + " with item count " + $oList.ItemCount

$collListItems = $oList.Items;

$count = $collListItems.Count - 1

for($intIndex = $count; $intIndex -gt -1; $intIndex--)

{

"Deleting : " + $intIndex

$collListItems.Delete($intIndex);

}
