9 # Check whether the Vala compiler exists in $PATH. If it is found, the
10 # variable VALAC is set pointing to its absolute path. Otherwise, it is
11 # simply set to 'valac'.
12 # Optionally a minimum release number of the compiler can be requested.
13 # If the ACTION-IF-FOUND parameter is given, it will be run if a proper
14 # Vala compiler is found.
15 # Similarly, if the ACTION-IF-FOUND is given, it will be run if no proper
16 # Vala compiler is found. It defaults to simply print a warning about the
17 # situation, but otherwise proceeding with the configuration.
