A caching helper for Henrietta which fetches eggs from various sources.
This egg installs a small program called henrietta-cache which reads a file containing egg-to-URI mappings. These URIs are expected to resolve to a so-called "release-info" file, which provides further instructions on how to fetch actual releases of the egg.
These releases are downloaded into a caching directory, which can then be served by henrietta for use by chicken-install.
Henrietta-cache can be invoked as follows:
henrietta-cache [-h] [-c|-cache-dir CACHEDIR] [-e|-egg-list EGGLIST]
The CACHEDIR points at the directory in which to place the cached files. It defaults to "cache". It will automatically create a subdirectory for each egg in the list and create a subdirectory called "tags" underneath those, in which it creates one directory for each release. This structure is used because it is expected by henrietta, and may change in the future.
The EGGLIST points to a file containing the list of eggs to fetch. It may be either a filename or an HTTP(S) URI.
