+**Purpose**:
+Sometimes you just need a basic script that outputs a pretty directory and file tree.  This script offers files and folders to ignore, and outputs a fancy directory tree.

+```powershell
+function Export-Tree {
+    param (
+        [string]$Path = ".",
+        [string]$OutFile = "directory_tree.txt"
+    )
+
+    $global:TreeLines = @()
+    $global:IgnoreList = @(

+        "Dependencies",
+        "Server",
+        "Agent"
+    )
