统计源代码行数的shell脚本

写了一个脚本，可以按模块统计源代码的行数，呵呵。

输出结果：

~ $ ./line-count [module]        [lines] [%]FRED             4744   17.67%dataset          8591   32.00%core             9025   33.61%image             803    2.99%tape             1339    4.99%license            16    0.06%jni              1621    6.04%util              264    0.98%test              446    1.66%total           26849

脚本如下：
