the mac/macfuse subdirectory needed to be added to the pythonpath in order to build a binary incorporating the mac fuse system. this change should make those modules accessible relative to the mac/ directory which is implicitly included in the .app build process.

This class alters / enhances `OptionParser` with *suboption handlers*.
|
|
|
|
That is, calling `sop.add_option('-x', subopt=foo)` installs a handler
|
|
which will be triggered if there is ``-x foo`` in the command line being
|
|
parsed (or, eg., ``-x foo,bar``).
|
|
|
|
Moreover, ``-x`` implicitly gets a handler which collects the unhandled
|
|
suboptions of ``-x`` into a `SubOptsHive` instance (accessible post festam
|
|
via the `x` attribute of the returned Values object). (The only exception
|
|
is when ``-x`` has *explicitly* been added with action ``store_hive``.
|
|
This opens up the possibility of customizing the ``-x`` handler at some
|
|
rate.)
|
|
|
|
Suboption handlers have all the nice features of normal option handlers,
|
|
eg. they are displayed in the automatically generated help message
|
|
(and can have their own help info).
