#----------------------------------introduction---------------------------------#
'''the aim of this tool is to ergolist the asset path
and create a "uiAsset.as" file to map the bitmaps to
"Embed" class

how to use this bat tool:
1.place this script file in the asset directory,and make sure
that all the bitmap file was in the current path or subpath

2.if you wanna provide a bitmap's 9scaleGrid info,config the
relative info into a file(default named: 9.txt) under the same
directory path of the bitmap,and info goes like this:
["bg0","scaleGridTop=55,scaleGridLeft=55,scaleGridBottom=64,scaleGridRight=65"]
or:
["all_same","scaleGridTop=55,scaleGridLeft=55,scaleGridBottom=64,scaleGridRight=65"]

3.run the script,then check if a codefile is generated correctly.
