# @2016.2.17 初始pngquant版本
|

# @2016.3.8 增加对音频的处理
|

#
|
||
# 使用pngquant对图片素材进行压缩，压缩后gradle脚本copyResource会将../res目录copy到目的地
|
||
# 使用lame处理mp3
|
||
# 由于pngquant/lame是需要系统额外安装的，故不将此命令写入gradle脚本
|
||
# Sample: brew install ImageMagick lame
|
||
#
|
||
# 选项：
|
||
# -s src dir of images, default ../res
