longDescription = ''
|
|
|
|
|
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.
