2 # any module from Tahoe-LAFS or its dependencies, and do not import any

7 # The semantics for requirement specs changed incompatibly in setuptools 8,
8 # which now follows PEP 440. The requirements used in this file must be valid
9 # under both the old and new semantics. That can be achieved by limiting
10 # requirement specs to one of the following forms:
12 # * >= X, <= Y where X < Y
13 # * >= X, != Y, != Z, ... where X < Y < Z...
15 # (In addition, check_requirement in allmydata/__init__.py only supports
16 # >=, <= and != operators.)
19 # We require newer versions of setuptools to build, but can handle
20 # older versions to run.
