You can see how v invokes the C backend compiler with `v -show_c_cmd source.v` . You can see how V invokes the C backend compiler with `v -show_c_cmd file.v` .
You can produce a .c file, *without* compiling it further with `v -o file.c file.v` . You can produce a .c file, *without* compiling it further with `v -o file.c file.v` .
That is useful, if you want to integrate v as a transpiler into the build system (probably using a Makefile) of an existing large C code base, or if you just want to read the produced C code.

You can pass `-g`, which has the effect of -debug, and in addition will make the debugger information to have v line numbers, instead of C ones (NB: this will make the intermediate .c file harder to read).
