"""
Write JavaScript code to be pasted into a Google Sheet to draw a calendar.

0. Update the data. Search for "Editable content" below.
1. Run this program.  It prints JavaScript code. Copy it.
2. Open a Google Sheet, either the existing Support Windows spreadsheet
    (https://docs.google.com/spreadsheets/d/1wtpoypH1XOPc_G6h9AUNXJ6XiNKD6dlkMP3lubdpE9I)
    or a new spreadsheet.
3. Select the "Support Windows" sheet or create a new sheet if it doesn't exist already.
4. Open the script editor (Extensions - Apps Script).
5. If there's any code there, delete it.
6. Paste the JavaScript code this program wrote.
7. Save the code.  The function picker at the top should select makeBarCalendar.
8. Click the Run tool on the toolbar.
9. Your sheet should now be populated with a beautiful calendar.
