PyQt4 HardwareManager

#                            PyQt4 HardwareManager
# 声明：
#     本软件主要是由于朋友说想要一个产品缺陷记录软件，主要用于记录产品缺陷，
# 通过产品序列号进行插入、查询，本来想用VC++ 6.0做，但是每次打开开发环境就
# 奔溃了，所以只能换一个开发环境，于是尝试用PyQt4进行原型开发，在开发过程中
# 发现，这确实是一个很好的思路，该软件可以换一种思路用于其他环境下，但就
# 目前而已，这仅仅是一个原型。

五、cat autorun.bat
    start pythonw.exe main.pyw
    exit

六、cat readme.txt
    一、文件说明：
        1. managerFile目录主要是程序生成的信息文件，不要去动它；
        2. pyhon2.7目录包含了python2.7、pyqt4的安装文件；
        3. autorun.bat是windows的批处理文件，双击运行，会自动main.pyw文件;
        4. 所有的.pyw文件是python程序文件;
        5. hardwaremanager.ui文件是qt Designer生成的文件，通过pyuic4.bat将ui文件转成ui_hardwaremanager.pyw;
        6. logo.ico是程序的ico文件。
    二、程序运行说明：
        1. 可以通过双击main.pyw文件运行；
        2. 可以通过双击autorun.bat文件运行。
