List any modules that are imported from the given package. This can be used
|
|
to determine what needs to be refactored to allow a package to be broken out
|
|
into a separately installed package. The package argument to the script
|
|
should be formatted as shown in these examples:
|
|
|
|
* scripts/dependencies/from_package.py xmodule
|
|
* scripts/dependencies/from_package.py openedx/features/course_experience
|
|
* scripts/dependencies/from_package.py cms/djangoapps/verify_student
|
|
|
|
This script counts on scripts/dependencies/enumerate.sh having already
|
|
been run in order to generate a dependency data file to work from.
