Right now, we're scraping section numbers out of the full text. This has the shortcoming of not working on ranges (only the first number in the range is picked up). SECTION.CSV, on the FTP site, lists all of them. It's real simple—here are the first few lines of the file right now:

"Bill_Id","Code Section"
HB1,"§ 2.2-3701,§ 2.2-3705.4,§ 22.1-287,§ 22.1-287.1,§ 23.1-405"," Administration of Government; Consumer Protection; Education; Freedom of Information; Institutions of Higher Education; Other Educational and Cultural Institutions"
HB2,"§ 22.1-298.1"," Armed Forces; Commissions, Boards, and Institutions Generally; Education; Teachers"
HB3,"§ 23.1-905.1"," Higher Education; Institutions of Higher Education; Other Educational and Cultural Institutions"
