* The Mythran Mud Economy Snippet Version 2 (used to be banking.c)
*
* Copyrights and rules for using the economy system:
*
* The Mythran Mud Economy system was written by The Maniac, it was
* loosly based on the rather simple 'Ack!'s banking system'
*
* If you use this code you must follow these rules.
* -Keep all the credits in the code.
* -Mail Maniac (v942346@si.hhs.nl) to say you use the code
* -Send a bug report, if you find 'it'
* -Credit me somewhere in your mud.
* -Follow the envy/merc/diku license
* -If you want to: send me some of your code
*
* All my snippets can be found on http://www.hhs.nl/~v942346/snippets.html
* Check it often because it's growing rapidly -- Maniac --

/* The Mythran mud economy system (bank and trading)
*
* based on:
* Simple banking system. by -- Stephen --
*
* The following changes and additions where
* made by the Maniac from Mythran Mud
* (v942346@si.hhs.nl)
*
* History:
* 18/05/96: Added the transfer option, enables chars to transfer
* money from their account to other players' accounts
* 18/05/96: Big bug detected, can deposit/withdraw/transfer
* negative amounts (nice way to steal is
* bank transfer -(lots of dogh)
* Fixed it (thought this was better... -= Maniac =-)
* 21/06/96: Fixed a bug in transfer (transfer to MOBS)
* Moved balance from ch->balance to ch->pcdata->balance
* 21/06/96: Started on the invest option, so players can invest
* money in shares, using buy, sell and check
* Finished version 1.0 releasing it monday 24/06/96
* 24/06/96: Mythran Mud Economy System V1.0 released by Maniac
*
*/
/*
BUG FIXES:
* 23/07/97: Make it less screwy in general by fixing it so that
* do_say actually executes, plus cleaned up some of
* the unnessecary \n\r's. --Jouster
