  45  sgl setup
  46  =========
  47  - ability to upload and unzip/tar a packaged module
  48  - file permission handling ideas from FUDforum installer
  49  - more user-friendly error messages from Gallery2
  50  - if no DB detected, prompt to create, otherwise offer to create tables
  51  
  52  
  53  php ini
  54  =======
  55  - deal with register_globals and set session.use_trans_sid = 0
  56  - allow_url_fopen = Off
  57  - detect and deal with safe_mode
  58  - magic_quotes must be off
  59  - file_uploads ideally enabled
  60  
  61  module setup
  62  ============
  63  - choose modules and permissions must be created and set at install time
  64  - attempt to
  65      - uncompress
  66      - move to correct location
  67      - apply user perms
  68      - apply prefs
  69      - add module's db tables to Config
  70      - load module's schema + data
  71      - add 'section' or 'screen' navigation links
  72      - register module in registry
