+ = NAME
+ aaron - Transaction Scheduling and exception handling machine
+ = SYNOPSIS
+ aaron [ ((*options*)) ]
+ == INTRODUCTION
+ ((*aaron*)) is an event scheduling and exception handling machine. ((*aaron*)) has a complex rules engine that makes it ideal for both monitoring of service, but also for scheduling the execution of events (ie: cron jobs).

+ =PHASE ONE CONFIG
+ The phase one config file is a simple configuration file that is required by
+ ((*aaron*)) to tell the program where configuration files and modules are, as
+ well as the names of the module directories (stats, event, response, etc.).
+ All information set by phase one configuration directives can be overridden
+ later by subsequent configuration directives.
+ ==PHASE ONE CONFIG FILE FORMAT
+ The phase one config has a simple format.  All lines beginning with a (({#})) are ignored.  All lines with spaces are ignored. All information in this file is stored in key/value pairs separated by (({=})) signs.
+ ==PHASE ONE CONFIG VARIABLES
+ --- module_path
+     Required. The path to the base modules directory.
+ --- action_mod_dir
+     Optional. Name of the directory within the ((*modules*)) directory that has ((*action*)) modules.  Defaults to (({action})).
+ --- response_mod_dir
+     Optional.  Name of the directory within the ((*modules*)) directory that has ((*response*)) modules.  Defaults to (({response})).
+ --- transaction_mod_dir
+     Optional.  Name of the directory within the ((*modules*)) directory that has ((*transaction*)) modules.  Defaults to (({transaction})).
