Generating a list of Biml Scripts and Descriptions

Our team has created several dozen Biml Scripts over the last few months... enough that it is tough to know exactly what we have. We use the following C# to enumerate the scripts (stored in a common location and included in all of our projects) and generate a Confluence wiki table. You'll have to modify this to adjust the output / path but it might be helpful to someone.

This assumes scripts have a Description annotation in the format <#@ annotation annotationtype="Description" tag="Summary" text="" #>

using System;
using System.Windows.Forms;
using System.IO;
using System.Text.RegularExpressions;
using System.Text;

class Script
{
  /// <summary>
  /// This script will write a Text file containing all the Biml Script Locations/Names/Descriptions.
  /// 
  /// The Description is pulled from an annotation in the format
  /// <#@ annotation annotationtype="Description" tag="Summary" text="<Description>" #>
  /// </summary>
  /// <param name="args">The args.</param>
  [STAThread]
  static public void Main(string[] args)
  {
    // Location to dump the output.
    var outputPath = @"C:\Temp\BimlScriptDocumentation.txt";

    // Set up the location where the Biml Scripts live.
    var edw3Trunk = Environment.GetEnvironmentVariable("BFG_BI_EDW3_TRUNK", EnvironmentVariableTarget.Machine);
    var bimlScriptPath = Path.Combine(edw3Trunk, "Framework", "BimlScripts");
    StringBuilder output = new StringBuilder();

    // Output the table header
    output.AppendFormat("||{0}||{1}||{2}||\r\n", "Path", "Script", "Description");

    // Loop over all the Biml files
    foreach(var file in Directory.GetFiles(bimlScriptPath, "*.biml", SearchOption.AllDirectories))
    {
      string relativePath = Path.GetDirectoryName(file).Remove(0, bimlScriptPath.Length+1);
      string scriptName = Path.GetFileNameWithoutExtension(file);
      string scriptContents = File.ReadAllText(file);
      string scriptDocumentation = " "; // Important!  Required for the table to format correctly.

      // Get the first "Description" annotation in the file (if one exists).
      string annotationRegex = "<\\#@(?:\\s+)annotation(?:\\s+)annotationtype=\"Description\"(?:\\s+)tag=\"Summary\"(?:\\s+)text=\"(.*?)\"(?:\\s+)\\#>";
      RegexOptions options = ((RegexOptions.IgnorePatternWhitespace | RegexOptions.Multiline) | RegexOptions.IgnoreCase);
      Regex reg = new Regex(annotationRegex, options);

      var groupCollection = reg.Match(scriptContents).Groups;

      if (groupCollection.Count >= 2)
      {
        scriptDocumentation = groupCollection[1].Value.ToString();
      }

      // Output the table row
      output.AppendFormat("|{0}|{1}|{2}|\r\n", relativePath, scriptName, scriptDocumentation);
    }

    // Write the output to a file; it's hard to get from the console.
    if (File.Exists(outputPath))
    {
      File.Delete(outputPath);
    }

    File.WriteAllText(outputPath, output.ToString());
  }
