Bug#500773: dzhandle: minor issues with extensions management

[Jonas Meurer]

Package: zope-common
Version: 0.5.45
Severity: normal

Hello,

I just discovered that dzhandle supports global Extensions management,
which I appreciate. But I also discovered minor bugs in dzhandles
extensions management:

- The dzhandle help doesn't mention either of list-extensions,
  add-extension and remove-extension so far. Only the manpage mentions
  them.

- 'dzhandle list-extensions' gives the same header as list-products:
  'Listing products available for all version(s)'. This is confusing as
  it actually list extensions and not products.

- Both /usr/share/zope/Extensions and /usr/local/share/zope/Extensions
  aren't provided, while the two respective Products do exist. At least
  the Products folder in /usr/local/share/zope is created by the
  zope-common postinst script, thus the respective Extensions folder
  should be created the same way.

- Many Extensions are one single python script. Nevertheless dzhandle
  seems to support only folders as extensions. It would be great if *.py
  files in the global Extensions folder could be treaded as extensions
  as well.

greetings,
 jonas
