+Name: LibGroupTalents-1.0
+Revision: $Rev: 55 $
+Author: Zek
+Documentation: http://wowace.com/wiki/LibGroupTalents-1.0
+SVN: svn://svn.wowace.com/wow/libgrouptalents-1-0/mainline/trunk
+Description: Talent Library abstraction layer to provide easy interface to the lower level system
+Dependancies: LibStub, CallbackHandler-1.0, LibTalentQuery-1.0
+License: GPL v3
+
+Purpose:
+	LibGroupTalents-1.0 is intended to do the following basic functions usually handled at the mod level.
+
+	- Maintain a raid wide table of talents, automatically updated on roster changes, notifying you on talent receipts.
+	- Provide easy access to talent queries (spec weight, spec name, specific talent presence)
+	- Monitor talent changes in players, and notify of changes (respec, talent swap, update after out of sight, level up)
+	- Monitor player roles, and notify of changes (melee, tank, healer, caster)
+	- Communicate directly with itself to other users to update talents via addon channel when possible
+
+Notes:
+	The LibTalentQuery-1.0 dependancy must be included before LibGroupTalents-1.0 in any lib.xml or mod side TOC declarations.
+
+Functions:
+	UnitHasTalent(unit, talentName[, group])-- Returns: Points spent in talent or nil
+	GUIDHasTalent(guid, talentName[, group])-- As UnitHasTalent
+	GetUnitTalentSpec(unitid[, group])		-- Returns: Dominant Tree, spent1, spent2, spent3
+	GetGUIDTalentSpec(guid[, group])		-- As GetUnitTalentSpec
+	GetUnitTalents(unit, refresh)			-- Returns: Raw talent information in form of table of 3 strings of points spent. The refresh arg will force a re-query of the unit's talents
+	GetGUIDTalents(guid, refresh)			-- As GetUnitTalents
+	GetUnitRole(unit)						-- Returns one of: "melee", "caster", "healer", "tank"
+	GetGUIDRole(guid)						-- As GetUnitRole
+	RefreshTalentsByUnit(unit)				-- Force a refresh of talents for the specific unit
+	RefreshTalentsByGUID(guid)				-- Force a refresh of talents for the specific player GUID
+	GetTreeNames(class)						-- Returns: The three talent tree names for that class (Note: These return values are only valid after a player of that class has been inspected)
+	GetTreeIcons(class)						-- Returns: The three talent tree icons for that class (Note: As above)
+	GetTalentCount()						-- Returns: Talent info got, Talent info missing
+	GetTalentMissingNames()					-- Returns: Comma delimited list of player names we're missing talents for
+	GetClassTalentInfo(class, talentName)	-- Returns: Max Rank, Icon, Tab, Tier, Column, Tree Index
+	GetUnitStorageString(unit)				-- Returns: An encoded data string containing talent information for the player which can be stored by mods to set in later sessions using SetStorageString()
+	GetGUIDStorageString(guid)				-- As GetUnitStorageString
+	SetStorageString(talentString)			-- Returns: true on success (applicable). Any second return value indicates the data was invalid and should not be kept
+	GetUnitGlyphs(unit[, group])			-- Returns: Up to 6 spell IDs for the currently assigned Glyphs (Note: For the moment, we can only see the glyphs of players running LibGroupTalents-1.0)
+	GetGUIDGlyphs(guid[, group])			-- As GetUnitGlyphs
+	UnitHasGlyph(unit, glyph [, group])		-- Returns: true if the player has the glyph associated with spellID or spellName (Note: For the moment, we can only see the glyphs of players running LibGroupTalents-1.0)
+	GUIDHasGlyph(unit, glyph [, group])		-- As UnitHasGlyph
+	PurgeAndRescanTalents()					-- Wipe current roster of all talents and rescan from start
+
+Convenience Functions (Similar to Blizzard API functions, but callable with a unit ID):
+	GetActiveTalentGroup(unit)				-- Returns: Active talent group for unit
+	GetNumTalentGroups(unit)				-- Returns: Number of talent groups for unit
+	GetNumTalentTabs(unit)					-- Returns: Number of talent tabs. Here's a clue; it's going to be 3...
+	GetTalentTabInfo(unit, tab[, group])	-- Returns: Tree Name, Tree Icon, Points Spent, Tree Background
+	GetNumTalents(unit, tab)				-- Returns: Number of talents for specified tree
+	GetTalentInfo(unit, tab, index[, group])-- Returns: Talent Name, Icon, Tier, Column, Points Spent, Max Rank (Note that preview return values are not given unless called with "player")
+	GetUnspentTalentPoints(unit[, group])	-- Returns: Number of un-spent talent points for the unit
+
+Events:
+	LibGroupTalents_Update(guid, unit, newSpec, n1, n2, n3 [, oldSpec, o1, o2, o3])	-- Received updated talents. If it's a respec, or old set is know, it passes the old info also (this is not sent if new talent scan is same as previous)
+	LibGroupTalents_UpdateComplete(guid1, guid2[, ...])	-- Sent when there are no more pending talent reads due (passes all GUIDs that were updated since last time this event was fired)
+	LibGroupTalents_Add(guid, unit, name, realm)	-- Unit added to talent roster (Talents not necessarily available yet, but this is the mod's chance to feed talents using SetStorageString)
+	LibGroupTalents_Remove(guid, name, realm)										-- Unit removed from talent roster (This is your last chance to store talents if required using GetUnitStorageString)
+	LibGroupTalents_RoleChange(guid, unit, newrole, oldrole)		-- Roles are: "melee", "caster", "healer", "tank"
+	LibGroupTalents_GlyphUpdate(guid, unit)			-- Fired when a player's glyphs change (Note: For the moment, we can only see the glyphs of players running LibGroupTalents-1.0)
