This task does absolutely nothing more than output the DDL for a database to a file.
该任务惟一要做的就是将一个数据库的DDL输出到文件中。
The .o files are placed in /tmp; specifically, SCons builds a directory tree in /tmp/username in which it stores output files so as to avoid altering the build tree more than absolutely necessary.
o 文件都放在 /tmp 中;具体来说,SCons 会在 /tmp/username 中创建一个目录树,并将输出文件放到这个目录中,从而避免在非绝对必要的情况下修改构建树。
If you're not absolutely sure you know what you're doing, avoid such a shortcut and use a proper XML output toolkit (such as 4suite's MarkupWriter).
如果不完全肯定自己在做什么,应避免这种捷径而使用适当的XML输出工具(如4suite的MarkupWriter)。
