GoCheese is Python private package repository and caching proxy.

It serves two purposes:

* hosting of private locally uploaded packages
  (conforming to PEP-0503 (Simple Repository API))
* proxying and caching of missing packages from upstream PyPI

To use it, just configure your pip.conf:

    [install]
    index-url = http://gocheese.host:8080/simple/

You can upload packages to it with twine:

    twine upload
        --repository-url http://gocheese.host:8080/simple/ \
        --username spam \
        --password foo dist/tarball.tar.gz

Root directory has the following hierarchy:

    root
      +-- public-package
      |     +- public-package-0.1.tar.gz.sha256
      |     +- public-package-0.2.tar.gz
      |     +- public-package-0.2.tar.gz.sha256
      +-- private-package
      |     +- .private
      |     +- private-package-0.1.tar.gz
      |     +- private-package-0.1.tar.gz.sha256
      |...

Each directory is a package name. When you trie to list unexistent
directory contents (you are downloading package you have not seen
before), then GoCheese will download all its package versions with
checksums and write then in .sha256 files. So you know what versions are
available at the moment. When you asks for particular package, then its
tarball is really downloaded and verified against the checksum. For
example in the root directory above we have downloaded only
public-package-0.2. Private packages contain .private file, indicating
that it must not be asked in PyPI if required version is missing.

-refresh URL behaves the same way as -simple one, but is always
refreshes package versions from PyPI when listing it. You can use it to
forcefully update package version.

Initially it was created as a fork of https://github.com/c4s4/cheeseshop,
but nearly all the code was rewritten. It has huge differences:

* no TLS support
* no YAML configuration, just command-line arguments
* no package overwriting ability
* no MD5-hashed passwords
* atomic packages store on filesystem
* proxying and caching of missing packages
* SHA256-checksummed packages (both uploaded and proxied one)

GoCheese is free software: see the file COPYING for copying conditions.
