Yet another ... 里的yet怎么理解？

http://en.wikipedia.org/wiki/Yet_another
Among programmers, yet another is an idiomatic qualifier in the name of a computer program, organisation, or event that is confessedly unoriginal.[1]
Stephen C. Johnson is credited with establishing the naming convention in the late 1970s when he named his compiler-compiler yacc (Yet Another Compiler-Compiler), since he felt there were already numerous compiler-compilers in circulation at the time.
Yet就理解成「已经有很多了」吧......

yet
[jet]
conj.
可是；然而
He worked hard, yet he failed.
他工作努力，可是他失败了。
[jet]
adv.
还，尚，仍
He has not come yet.
他还没有来。
She is yet a child.
她还是个孩子。
He was poor, yet happy.
他很穷，可是很快乐。
The driver's not yet conscious after the accident.
驾驶员在出事后,还没有苏醒过来。
The doctors have not yet decided how the woman died.
医生们尚未确定这位妇女的死因。

理解成“已然”比较好吧

又一个xxx

就是“卧槽怎么还有”的意思

yet = 又

yet 里的y怎么理解？e怎么理解？t怎么理解？

还没有

我觉得是语气词多一点

仅仅，语气

问了下“二师兄”的理解：

[6:11:22 PM CDT] Me: Hi 二师兄, I got a English question. :) There are a bunch of tools, such as yaml, which starts with “yet another”. What exactly does "yet" means in those situations? Does the author trying to be humble? (yet means not yet, almost) Or somthing else?
[6:11:54 PM CDT] 二师兄: yet as in another one
[6:11:59 PM CDT] 二师兄: being ironic
[6:12:35 PM CDT] 二师兄: as in there are already a lot of (x)aml stuff, and this is 'yet' another one
[6:13:26 PM CDT] 二师兄: because, a lot of people ask, why is there a need for yet another {whatever} isn't {whatever existing tool(s)} enough?
[6:14:03 PM CDT] 二师兄: like why do we need to invent yet another drupal management tool when there are already package managers we can use.

貌似“又”，“已经很多”是正解。谢谢楼上各位。
