1usage: valgrind [options] prog-and-args
2
3  tool-selection option, with default in [ ]:
4    --tool=<name>             use the Valgrind tool named <name> [memcheck]
5
6  basic user options for all Valgrind tools, with defaults in [ ]:
7    -h --help                 show this message
8    --help-debug              show this message, plus debugging options
9    --version                 show version
10    -q --quiet                run silently; only print error msgs
11    -v --verbose              be more verbose -- show misc extra info
12    --trace-children=no|yes   Valgrind-ise child processes (follow execve)? [no]
13    --trace-children-skip=patt1,patt2,...    specifies a list of executables

15    --trace-children-skip-by-arg=patt1,patt2,...   same as --trace-children-skip=
16                              but check the argv[] entries for children, rather
17                              than the exe name, to make a follow/no-follow decision
