|
|
|
+Sometime after v1.9.3, micropython-lib's directory structure was cleaned up and
|
|
|
+enhanced with manifest files.
|
|
|
+
|
|
|
+Though cleaner, it means it cannot be directly copied into the target.
|
|
|
+This script is during build process to perform that conversion.
|
|
|
+
|
|
|
+It makes use of manifestfile.py, which is normally located in micropython's
|
|
|
+tool directory.
|
|
|
+
|
|
|
+It also depends on the micropython-lib that is cloned in lib/micropython-lib
|
|
|
+during build.
