NAME

only_action -- A build check method that only looks at the command.

USAGE

   build_check only_action

DESCRIPTION

The only_action method will only cause a rebuild if the command string changes. This method is intended to be used for commands that create an output file based on the names of their inputs, rather than the contents, like &echo $(inputs) -o $(output) or &ln -fr $(input) $(output) .
