main.cgi:

  • Removed commented legacy initialization code
  • Tweaked all SQL except for one section that needs serious redesigning to tighten any further. Adjusted processing on data returned via fetchrow_array() to make sure it's correct.
  • Property svn:executable set to *
  • Property svn:keywords set to Date Rev Author
