+ help
+ run-parts is a utility designed to run all the scripts in a directory.
+
+ It is useful to set up a directory like cron.daily, where you need to
+ execute all the scripts in that directory.
+
+ In this implementation of run-parts some features (such as report
+ mode) are not implemented.
+
+ Unless you know that run-parts is used in some of your scripts
+ you can safely say N here.

+ help
+ Support long options for the run-parts applet.

+config FEATURE_RUN_PARTS_FANCY
+ bool "Support additional arguments"
+ default y
+ depends on RUN_PARTS
+ help
+ Support additional options:
+ -l --list print the names of the all matching files (not
+ limited to executables), but don't actually run them.
+
+config START_STOP_DAEMON
+ bool "start-stop-daemon"

+ -n,--name PROCESS_NAME Look for processes by matching PROCESS_NAME
+ with comm field in /proc/$PID/stat.
+ Only basename is compared:
+ "ntpd" == "./ntpd" == "/path/to/ntpd".
+[TODO: can PROCESS_NAME be a full pathname? Should we require full match then
+with /proc/$PID/exe or argv[0] (comm can't be matched, it never contains path)]
+ -x,--exec EXECUTABLE Look for processes that were started with this
+ command in /proc/$PID/exe and /proc/$PID/cmdline
+ (/proc/$PID/cmdline is a bbox extension)
+ Unlike -n, we match against the full path:
+ "ntpd" != "./ntpd" != "/path/to/ntpd"
+ -p,--pidfile PID_FILE Look for processes with PID from this file
+
+Options which are valid for --start only:
+ -x,--exec EXECUTABLE Program to run (1st arg of execvp). Mandatory.
+ -a,--startas NAME argv[0] (defaults to EXECUTABLE)
+ -b,--background Put process into background
+ -N,--nicelevel N Add N to process' nice level
+ -c,--chuid USER[:[GRP]] Change to specified user [and group]
+ -m,--make-pidfile Write PID to the pidfile
+ (both -m and -p must be given!)
+
+Options which are valid for --stop only:
+ -s,--signal SIG Signal to send (default:TERM)
+ -t,--test Exit with status 0 if process is found
