| """Command line tools. |
| |
| This module contains implementations for several performance related command |
| line tools. |
| |
| Each submodule is a largely independent tool, which should expose a Main() |
| function to be called by a thin executable script made available in the parent |
| directory. |
| |
| For example, the code of `tools/perf/my_fancy_tool` should mostly be: |
| |
| #!/usr/bin/env vpython |
| import sys |
| from command_line_tools import my_fancy_tool |
| |
| if __name__ == '__main__': |
| sys.exit(my_fancy_tool.Main()) |
| |
| Reusable code that could be shared by many of these tools should be placed |
| under `tools/perf/core`. |
