## # better if Twisted would declare that it requires pywin32 if it is going to offer process

## # management. Then the specification and the evolution of Twisted's reliance on pywin32 can

|
## # be confined to the Twisted setup data, and Tahoe can remain blissfully ignorant about such

|
## # things as if a future version of Twisted requires a different version of pywin32, or if a
|
|
## # future version of Twisted implements process management without using pywin32 at all,
|
|
