The config option max_chapter should be parsed as an integer.

在.project.ini中设置max_chapter为1500

[book]
max-chapter=1500

运行"txt2mobi test"时报如下错误：

$ txt2mobi test

文件字符集: GBK

    ct = len(self.chapters) / config.max_chapter
TypeError: unsupported operand type(s) for /: 'int' and 'str'

发现下面的code中get应该改成getint: https://github.com/ipconfiger/txt2mobi/blob/master/txt2mobi/utilities.py

    @property
    def max_chapter(self):
        try:
            return self.cf.get('book', 'max-chapter')
        except:
            return 1500
