// soong_glob is the command line tool that checks if the list of files matching a glob has
|
|
// changed, and only updates the output file list if it has changed. It is used to optimize
|
|
// out build.ninja regenerations when non-matching files are added. See
|
|
// android/soong/common/glob.go for a longer description.
