使用Python编写，可以设置源码目录，排除目录，收集文件类型，输出目标文件，是否允许空白，编码等。

使用示例：

python zhuzuoquan.py -s D:\pythoncode\projectname \
-e debug,release \
-t .h,.cpp \
-en gb18030 \
-o result.txt

zhuzuoquan.py 代码

#!/usr/bin/python
# -*- coding: utf-8 -*-

    description='著作权代码收集工具', usage='''

    ''')
parser.add_argument('-s', help='源文件目录', required=True)
parser.add_argument('-e', help='排除目录，多个用半角逗号分割', )
parser.add_argument('-t', help='扩展名，多个用半角逗号分割', required=True)
parser.add_argument('-o', help='输出文件')
parser.add_argument('-el', help='允许空白行')
parser.add_argument('-en', help='编码', default='utf-8')
