The others start with a capital letter. It would be better if "show this help message and exit" started with a capital letter. But, it comes from the library, so I do not know how to change it. I changed our code to make it consistent, but starting them with a capital letter is a preferred style, I can do as you suggest. Currently, the help looks like follows: ---------------->8----------------------- masahiro@oscar:~/ref/linux$ ./scripts/gen_compile_commands.py -h usage: gen_compile_commands.py [-h] [-d DIRECTORY] [-o OUTPUT] [--log_level LOG_LEVEL] Creates a compile_commands.json database from kernel .cmd files optional arguments: -h, --help show this help message and exit -d DIRECTORY, --directory DIRECTORY Path to the kernel source directory to search (defaults to the working directory) -o OUTPUT, --output OUTPUT The location to write compile_commands.json (defaults to compile_commands.json in the search directory) --log_level LOG_LEVEL The level of log messages to produce (one of DEBUG, INFO, WARNING, ERROR, CRITICAL; defaults to WARNING) ---------------->8----------------------- Thanks.

I think the help message of the -d option is somewhat misleading. Path to the kernel source directory to search (defaults to the working directory) The part "kernel source directory" is the source of the confusion. Some people misunderstand as if this script did not support separate output directories. Actually, this script also works for out-of-tree builds. You can use the -d option to point to the object output directory, not to the source directory. It should match to the O= option used in the previous kernel build, and then appears in the "directory" field of compile_commands.json. Reword the help message.
