 {{{
 <zooko> dstufft: we have a packaging mystery.  [20:04]
 <dstufft> what's up  [20:05]
 <dstufft> oh
 <dstufft> setuptools 8 implements PEP 440
 <dstufft> PEP 440 makes the meaning of , change from "a bunch of arbitrary
           confusing crap that PJE invented in the past" to "AND"  [20:06]
 <zooko> Oh boy.
 <dstufft> and a single version cannot be equal to 2.1.0 AND 2.3.0 and also

           greater than or equal to 2.4.1  [20:07]

 <dstufft> well it makes the specifiers follow a consistent and easy to
 follow
