ELPA deployment library

This library provides elpa-deploy: a complement to the function package-upload-file from package-x.el, which automatizes the deployment of simple and multi-file packages. This function automatizes the upload of a library to an ELPA directory so that no other action is needed. Particularly useful for rapid ELPA deployment aiding testing and releases. The procedures automatically taken care of consist of updating the version field of a package source using the current time-stamp, generating its tar archive if multi-file, and uploading the results to a specified ELPA directory, while deleting any previous version of the same package already deployed.
