1 Introduction

[WARNING: This project is still half-baked, but I intend to bake it
fully. I recommend waiting.]

ZAWS is a library for writing interfaces to Amazon Web Services
(AWS). It provides code to do common tasks related to creating &
authenticating requests and processing responses.

The source code is hosted at https://github.com/xach/zaws/

For full documentation, see doc/index.html.

5 Definitions

Definitions are sorted by export status, category, package, and then by lexicographic order.

5.1 Exported definitions

5.1.1 Special variables

Special Variable: *credentials*

The credentials used for authenticating AWS requests. Built-in credentials can be a list, a pathname, or a string designating a pathname. For a list, the first two elements are used as the access key and secret key, and the third element, if present, is the session token. For a pathname, the first two lines of the file are the access key and secret key, and the third line, if present, is the session token.
