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