+.SYNOPSIS
+  This is a helper function that runs a scriptblock and checks the PS variable $lastexitcode
+  to see if an error occcured. If an error is detected then an exception is thrown.
+  This function allows you to run command-line programs without having to
+  explicitly check the $lastexitcode variable.
+
+.EXAMPLE
+  exec { svn info $repository_trunk } "Error executing SVN. Please verify SVN command-line client is installed"
+#>
+function Exec
+{
+	[CmdletBinding()]
+	param(
+		[Parameter(Position=0,Mandatory=1)][scriptblock]$cmd,
+		[Parameter(Position=1,Mandatory=0)][string]$errorMessage = ($msgs.error_bad_command -f $cmd)
+	)
+	& $cmd
+	if ($lastexitcode -ne 0) {
+		throw ("Exec: " + $errorMessage)
+	}
+}
