# In the third case, running 'python -m debugpy' will not work because the module is not installed
# in any environment. Running 'python <path_to_debugpy>' will work, just like the second case.
# But running 'debugpy' will not work because even though the entry point is defined,
# that path is not in sys.path, so 'import debugpy' will fail. So just like in the second case,
# we need to modify sys.path[0].
# in any environment. Running 'python <install_dir>/debugpy' will work, just like the second case.
# But running the entry point will not work because python doesn't know where to find the debugpy module.

# In this case, no changes to sys.path are required. You just have to do the following before calling
# the entry point:
# 1. Add <install_dir> to PYTHONPATH.
# On Windows, this is set PYTHONPATH=%PYTHONPATH%;<install_dir>
# 2. Add <install_dir>/bin to PATH. (OPTIONAL)
# On Windows, this is set PATH=%PATH%;<install_dir>\bin
# 3. Run the entry point from a command prompt
# On Windows, this is <install_dir>\bin\debugpy.exe, or just 'debugpy' if you did the previous step.
