+In this file you can define, which mercs should be available on M.E.R.C website.
+This works for USE_PROFILE_DATA_FROM_XML = TRUE (using MercProfiles.xml) and FALSE (using BinaryData\Prof*.dat).
+If you want to hide any merc from M.E.R.C website, just delete the entry.
+
+	uiIndex:				0 - 254
+	Name:					Optional Name of the merc
+	MercBioID:				ID from the file "BinaryData\Mercbios.edt" file. Set this to -1 and no bios will be shown for the merc.
+							INFO: See list with entries below.
+	Drunk:					If you set this to 1, then the merc should also have a drunken profile defined in MercProfiles.xml/Prof*.dat
+							There also has to be an entry here in this file right underneath (with uiIndex + 1) the "normal" profile.
+							INFO: In vanilla JA2, Larry has a "normal" and a "drunken" profile.
+	AlternateIndex:			If <Drunk> is set to 0, you can always set this to -1. This indicates that there is no additional drunken profile for ther merc.
+							If <Drunk> is set to 1, then also an additional "drunken" profile has to exist.
+							In both profiles (normal, drunken) set the <AlternateIndex>, which points to the <uiIndex> of the alternating profile.
+	StartMercsAvailable:	Set to 1 and the merc is available at the beginning. Set to 0 and merc will be available after X (<usDay>) days.
+	NewMercsAvailable:		Accessible mercenary in the next day. Just set this to 0 for all mercs. This will only be set internal ingame.
+	ProfilId:			 	uiIndex from MercProfiles.xml/Prof*.dat.
+	usMoneyPaid:			The amount of money you have to pay Speck for this merc to show up on the website. If set to 0 then cost is taken from MercProfiles.xml/Prof*.dat.
+	usDay:					When <StartMercsAvailable> is set to 0, you can set the days, when the merc should be available in M.E.R.C.
+							For example, if you set <usDay> to 3, the merc will be available on Day 3 + 1 day offset on the website. 
+							Also the total amount of money you paid Speck has to be greater than <usMoneyPaid> for the merc to show up.
+   
+ 
+ The following list shows the records defined in "BinaryData\Mercbios.edt". Use this for the <MercBioID> tag.
