Since the tool is exposed more prominently now, we should clear up what it is and note that it is to be considered unstable, i.e. we may change it if the necessity arises. (In practice it is probably going to be fairly stable though, as compiler interfaces tend to be quite stable.) Should we add a version?

|
|
expand-response-params is a tool that allows for obtaining a full list of all
|
|
arguments passed in a given compiler command line including those passed via
|
|
so-called response files. The nixpkgs wrapper scripts for bintools and C
|
|
compilers use it for processing compiler flags. As it is developed in
|
|
conjunction with the nixpkgs wrapper scripts, it should be considered as
|
|
unstable and subject to change.
