I just wrote some commandlet as part of the Revision Framework to dumb the contents of a package called RevisionListObjectsCommandlet.
G:\Development\Revision\System>rfcc listobjects FreeClinic
Package FreeClinic
Package Brick
Texture FC_Atrium_A
Texture FC_AtriumWall
Texture FC_Wall_05
Palette Palette1
Palette Palette3
Package Concrete
Texture FC_PlainCeiln
Texture FC_Wall_01
Texture FC_Wall_02
Texture FC_Wall_03
Palette Palette25
Palette Palette29
Package Metal
Texture FC_Sign_01
Palette Palette2
Package Paper
Texture FC_EyeTest
Texture FC_poster_A
Texture FC_Services
Palette Palette11
Package Textile
Texture FC_BedTop_A
Palette Palette41
Package Tiles
Texture FC_MainFloor
Palette Palette39
In the right column the Object name is displayed while in the first column the Class of the Object is displayed. The indention is to display in which relation the Objects are, e.g. The Texture FC_Atrium_A has the outer object Brick (called group in this case), which in turn has the package FreeClinic as outer, which is the actual texture package. As a minor note: Groups are actually of class Package.
Things get even more interessting when looking at Packages with unreal scripts inside:
Class RevisionRootWindow
Function ApplyRootWindowSettings
FloatProperty InhardcodedHeight
FloatProperty InhardcodedWidth
FloatProperty InhMargin0
FloatProperty InhMargin1
IntProperty InhMultiplier
FloatProperty InvMargin0
FloatProperty InvMargin1
IntProperty InvMultiplier
ByteProperty InwinHAlign
ByteProperty InwinVAlign
FloatProperty Inx
FloatProperty Iny
BoolProperty bMenuMainSinglePlayerOnly
Function ClampMousePosition
Function ConditionalBindMultiplayerKeys
StrProperty Alias
IntProperty i
StrProperty keyBuySkills
StrProperty keyKillDetail
StrProperty KeyName
StrProperty keyScores
StrProperty keyTalk
StrProperty keyTeamTalk
IntProperty ForcedMaxScale
FloatProperty HorizontalDivisor
Function InitWindow
Function ModifyNewChild
ObjectProperty NewKidOnTheBlock
ObjectProperty NewParent
Function MutateClientScriptClass
ClassProperty InClass
ClassProperty ReturnValue
Function MutateNewChild
ClassProperty DesignatedClass
ObjectProperty NewParent
Function ResizeRoot
ObjectProperty Canvas
IntProperty hMult
IntProperty vMult
TextBuffer ScriptText
FloatProperty VerticalDivisor
It also has commandline switches to change the output, e.g. Björn wants to list all Pawn Classes used inside a map which are displayed by PathName and not just their name, so he would run sth. like:
G:\Development\Revision\System>rfcc listobjects -cp -co 00_Training pawn
