+This directory is dedicated for user-supplied scripts/executables.
+vifm modifies its PATH environment variable to let user run those
+scripts without specifying full path.  All subdirectories are added
+as well.  File in a subdirectory overrules file with the same name
+in parent directories.  Restart might be needed to recognize files
+in newly created or renamed subdirectories.
