Hello! Below is set of patches, that (1-20) implement new module (system foreign declarative), that simplifies writing bindings to foreign C functions and provides documentation to it. This module is extracted from abandoned guile-bash project.
Rest 5 patches (21-25) introduce module (ice-9 xattr), that provide Scheme interface to extended filesystem attributes, and is proof-of-usefulness of (system foreign declarative) module. There actually should also be patch 26, that write documentation for xattr module, but * I am not sure, in which file under docs/ref to put it in * I think, what is already done deserves review. If you wish, I could collapse these patches. Thanks for your review time. PS. Please, keep me in CC, I am not subscribed to list.
