Important Note!!
|
||||
================
|
||||
|
||||
The purpose of this folder is to contain files that are auto-generated by the Projucer,
|
||||
and ALL files in this folder will be mercilessly DELETED and completely re-written whenever
|
||||
the Projucer saves your project.
|
||||
|
||||
Therefore, it's a bad idea to make any manual changes to the files in here, or to
|
||||
put any of your own files in here if you don't want to lose them. (Of course you may choose
|
||||
to add the folder's contents to your version-control system so that you can re-merge your own
|
||||
modifications after the Projucer has saved its changes).

Important Note!!
|
||||
================
|
||||
|
||||
The purpose of this folder is to contain files that are auto-generated by the Projucer,
|
||||
and ALL files in this folder will be mercilessly DELETED and completely re-written whenever
|
||||
the Projucer saves your project.
|
||||
|
||||
Therefore, it's a bad idea to make any manual changes to the files in here, or to
|
||||
put any of your own files in here if you don't want to lose them. (Of course you may choose
|
||||
to add the folder's contents to your version-control system so that you can re-merge your own
|
||||
modifications after the Projucer has saved its changes).
