+config BR2_PACKAGE_MLOCATE
+	bool "mlocate"
+	help
+	  mlocate is a locate/updatedb implementation. The 'm' stands for
+	  'merging': updatedb reuses the existing database to avoid
+	  rereading most of the file system, which makes updatedb
+	  faster and does not trash the system caches as much.
+
+	  The mlocate utility is intended to be completely compatible to
+	  slocate (Security Enhanced version of the GNU locate). 
+	  It also attempts to be compatible to GNU locate, when it does 
+	  not conflict with slocate compatibility.
