+.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)
+    }
+}
