Package: devscripts Version: 2.10.46 Severity: wishlist Tags: patch Howdy,
In tuning my packaging workflow, I wanted an automated tool for querying the Debian archive for the latest available version of the current package, and emitting the version string. Please find attached ‘dlatest’, a shell program that makes use of ‘parsechangelog’ and ‘rmadison’ to do this job. It has full option parsing and a standard help message, but currently no manpage. I hope this can be included in the ‘devscripts’ package. -- \ “I must have a prodigious quantity of mind; it takes me as much | `\ as a week sometimes to make it up.” —Mark Twain, _The Innocents | _o__) Abroad_ | Ben Finney <b...@benfinney.id.au>
