+ Record "stamp" dependency. It reads @code{stdin} and stores its hash
+ in the dependency database. It is not used anyhow, it is dummy. Read
+ about @ref{Stamping, stamping} in the FAQ. It is left only for
+ compatibility with some other implementations.
+@item redo-targets, redo-ood
+ Show all known targets, possibly limited by specified directories.
+ @command{redo-ood} shows only the out-of-date ones.
+@item redo-sources
+ Recursively show all source files the given targets depend on.
+@item redo-affects
+ It is not in other distributions, but it is some kind of opposite of
+ @command{redo-sources} -- shows the targets that will be affected by
+ specified files change.
