## this is a simple script to use the github API for release versions.
## this requires the egg has a variable for GITHUB_PACKAGE, VERSION and MATCH (match is to match the filename in some way)
## this supports using oauth/personal access tokens via GITHUB_USER and GITHUB_OAUTH_TOKEN (both are required.)
## if you are getting hit with GitHub API limit issues then you need to have the user and token set.
