5 Writing Recipes in Rules
**************************

The recipe of a rule consists of one or more shell command lines to be
executed, one at a time, in the order they appear.  Typically, the
result of executing these commands is that the target of the rule is

always interpreted by `/bin/sh' unless the makefile specifies
otherwise.  *Note Recipe Execution: Execution.
