# make 编译并下载
# make VERBOSE=1 显示编译详细过程
# make clean 清除编译临时文件
#
# 注意： Linux 下编译方式：
#     1. 从 http://pkgman.jieliapp.com/doc/all 处找到下载链接
#     2. 下载后，解压到 /opt/jieli 目录下，保证
#       /opt/jieli/common/bin/clang 存在（注意目录层次）
#     3. 确认 ulimit -n 的结果足够大（建议大于8096），否则链接可能会因为打开文件太多而失败
#       可以通过 ulimit -n 8096 来设置一个较大的值
