dh-make指定包含低线_的构建目录

　　之前使用dh-make，都是使用-的格式。因为构建后的安装文件统一改用低线_，所以吾想构建目录也换成低线。然后报错了：

For dh_make to find the package name and version, the current directory
needs to be in the format of -.  Alternatively use the
_-p flag using the format _ to override it.
The directory name you have specified is invalid!

Your current directory is:
/home/tsit/Linux-Builder-5.0/cn.ts-it.office_5.0.0.500
Perhaps you could try going to directory where the sources are?

 　　一开始没注意，后来仔细研究了一下，意思就是使用_要特别指定。于是吾就：

BUILD_ACTION_DIR=cn.ts-it.office_5.0.0.6

dh_make \
    -p ${BUILD_ACTION_DIR} \
    --createorig -s -y

 　　顺利完成。
