这应该是有帮助的。维基百科通常对计算机相关的问题很有帮助。

维基百科有一些信息，虽然它不是最好的处理方式：

我知道的lusers是如此无能为力，如果他们被扼杀在线索

麝香并放在角质线索的中间，在线索舞会上

晚上线索欢乐时光，他们仍然无法得到线索。

Wikipedia has some information, although it''s not the greatest treatment:

"The lusers I know are so clueless, that if they were dipped in clue
musk and dropped in the middle of pack of horny clues, on clue prom
night during clue happy hour, they still couldn''t get a clue."
--Michael Girdwood, in the monastery

它并不总是作为一个单独的程序实现。在许多编译器中，它现在是主编译器的一部分。因此，如果您使用GCC，那么-E将使用GCC。 flag只运行

预处理器。

Its not always implemented as a seprate program. In many compilers its now
part of the main compiler. So if you use GCC then the "-E" flag only run the
pre-processor.
