apps/NxWidgets README File |
||||
========================== |
||||
|
||||
The NxWidgets and NxWM libraries don't physically reside in the apps/ source |
||||
tree. The source code actually resides at the top level NxWidgets/ |
||||
directory. This directory is just a kludge...it is here only support |
||||
configuration of NxWidgets and NxWM. |
||||
|
||||
The only files that reside in this directory are (1) this README.txt file |
||||
and (2) the Kconfig file to support NxWidgets configuration. This is a |
||||
duplicate of the NxWidgets file that you can file at NxWidgets/Kconfig. |
