This adds a warning to the top of each “boot” package that reads: Note: this package is used for bootstrapping fetchurl, and thus cannot use fetchpatch! All mutable patches (generated by GitHub or cgit) that are needed here should be included directly in Nixpkgs as files. This makes it clear to maintainer that they may need to treat this package a little differently than others. Importantly, we can’t use fetchpatch here due to using <nix/fetchurl.nix>. To avoid having stale hashes, we need to include patches that are subject to changing overtime (for instance, gitweb’s patches contain a version number at the bottom).

longDescription = ''
|
|
The libffi library provides a portable, high level programming
|
|
interface to various calling conventions. This allows a
|
|
programmer to call any function specified by a call interface
|
|
description at run-time.
|
|
|
|
FFI stands for Foreign Function Interface. A foreign function
|
|
interface is the popular name for the interface that allows code
|
|
written in one language to call code written in another
|
|
language. The libffi library really only provides the lowest,
|
|
machine dependent layer of a fully featured foreign function
|
|
interface. A layer must exist above libffi that handles type
|
|
conversions for values passed between the two languages.
