WTG File Format Questions

War3map.wtg: The triggers definition file

Header:
CHAR[4]: file ID (WTG!)
LONG: wtg file format version = 4 
LONG: number "a" of triggers categories 
"a" times a category definition structure*
LONG: number "b" ???
LONG: number "c" of variables
"c" times a variable definition structure**
LONG: number "d" of triggers
"d" times a trigger definition structure***

*Category Definition Structure:
LONG: category index
STRING: category name

**Variable Definition Structure:
STRING: variable name
STRING: variable type
LONG: number "e" ???
LONG: array status: 0=not an array, 1=array
LONG: initialisation status: 0=not initialized, 1=initialized
STRING: initial value (STRING)

***Triggers Definiton Structure:
STRING: trigger name
STRING: trigger description
LONG: enable state: 0=disabled, 1=enabled
LONG: custom text trigger state: 0=not a custom text trigger, 1=custom text trigger (use data in the WCT)
LONG: initial state: 0=initially on, 1=not initially on
LONG: ???
LONG: index of the category the trigger beLONG:s to
LONG: number "i" of event-condition-action (ECA) function
"i" times an ECA function definition structure*(4) (if it's a custom text trigger i should be 0 so we don't have 

this section)

*(4)ECA function definition structure
LONG: function type: 0=event, 1=condition, 2=action
STRING: function name
LONG: enable state: 0=function disabled, 1=function enabled
"x" times a parameter structure*(5). x depends of the function and is hardcoded.

*(5)Parameters Structure:
LONG: 0=preset, 1=variable, 2=function
STRING: parameter value
LONG: ???
LONG: ???
