But it shouldn't print a warning(!). If an application wants to replace a
file, then stuff shouldn't appear on stdout as a result.

While it may be problem to distribute them to other sites, that is not up
to the library. If I want compression, then I should get compression. A
library module should not determine application-level policy.
The warning that __init__ prints shouldn't be there.
Really: there should not be a single "print" in the library (well,
printdir() is fine... that's what it is supposed to do; printing in the
test code would be fine). In normal, or even exceptional(!), operation
there should never be a print.

I definitely agree with JimA here. For example, maybe we want bzip
compression in there. Sure, non-portable, but that's my problem :-)
