// *** Code sequence for startup ***
// IMPORTANT: These items are in a carefully constructed order. DO NOT REARRANGE
// without checking with experienced devs! Various subtle things WILL break.
//
// A Get the current CPU time so we know how long all of this takes
// B Remove output buffering so we are in control of text sent to user
// C Remove registered globals (SECURITY for all following code)
// D Setup PHP error handling (now we can see php errors ;))
// E Setup other PHP essentials
// F Grab e107_config to get directory paths
// G Retrieve Query from URI (i.e. what are the request parameters?!)
// H Initialize debug handling (NOTE: A-G cannot use debug tools!)
// I: Sanity check to ensure e107_config is ok
// J: MYSQL setup (NOTE: A-I cannot use database!)
// K: Compatibility mode
// L: Retrieve core prefs
// M: Subdomain and language selection
// N: Other misc setups (NOTE: Put most 'random' things here that don't require user session or theme
// O: Start user session
// P: Load theme
// Q: Other setups
