| // The toolexec program is a helper program for cmd/cover tests. |
| // It is used so that the go tool will call the newly built version |
| // of the cover program, rather than the installed one. |
| // |
| // The tests arrange to run the go tool with the argument |
| // -toolexec="/path/to/toolexec /path/to/testcover" |
| // The go tool will invoke this program (compiled into /path/to/toolexec) |
| // with the arguments shown above followed by the command to run. |
| // This program will check whether it is expected to run the cover |
| // program, and if so replace it with /path/to/testcover. |
