* The auxiliary file src/etc/pkg/modpath.iss contains a
library routine compiled, by Inno Setup, into the Windows
installer binary. This file is licensed under the LGPL,
version 3, but, in our legal interpretation, this does not
affect the aggregate "collected work" license of the Rust
distribution (MIT/ASL2) nor any other components of it. We
believe that the terms governing distribution of the
binary Windows installer built from modpath.iss are
therefore LGPL, but not the terms governing distribution
of any of the files installed by such an installer (such
as the Rust compiler or runtime libraries themselves).
* The src/rt/miniz.c file, carrying an implementation of
RFC1950/RFC1951 DEFLATE, by Rich Geldreich
<richgel99@gmail.com>. All uses of this file are
permitted by the embedded "unlicense" notice
(effectively: public domain with warranty disclaimer).
* LLVM. Code for this package is found in src/llvm.

* Additional copyright may be retained by contributors other
than Mozilla, the Rust Project Developers, or the parties
enumerated in this file. Such copyright can be determined
on a case-by-case basis by examining the author of each
portion of a file in the revision-control commit records
of the project, or by consulting representative comments
claiming copyright ownership for a file.
For example, the text:
"Copyright (c) 2011 Google Inc."
appears in some files, and these files thereby denote
that their author and copyright-holder is Google Inc.
In all such cases, the absence of explicit licensing text
indicates that the contributor chose to license their work
for distribution under identical terms to those Mozilla
has chosen for the collective work, enumerated at the top
of this file. The only difference is the retention of
copyright itself, held by the contributor.
