-- Check whether some CPM tool is available, i.e., either in the current -- path or in the CPM bin directory. If it is not available, -- skip the command with an error message how to install the tool from -- the package (specified in the second argument). Otherwise, continue with -- the last argument by passing the name of the CPM tool. |
