"""This file defines the path to the Python files within this package.

There are two cases:
|
||
|
|
|
||
|
|
(1) This is a source tree being run interactively by a developer, in
|
||
|
|
which case the Python files are found in package/src/*/*.py. This
|
||
|
|
case also breaks down into two sub-cases: (1a) we are using the
|
||
|
|
ctattach tools, in which case we should look for the files in the
|
||
|
|
actual source directory according to the ctattach variables, or
|
||
|
|
(1b) we are not using the ctattach tools, in which case the files
|
||
|
|
are right where we expect them to be.
|
||
|
|
|
||
|
|
(2) This is an installed tree being run by an end-user, in which case
|
||
|
|
the Python files are found in package/*/*.py. In this case, this
|
||
|
|
file doesn't really need to be installed; an empty __init__.py
|
||
|
|
file to define the package would serve just as well. But the file
|
||
|
|
is crafted so that it will do no harm if it is installed.
