The Source Ruckus Packager (SRP) is a lightweight, yet fully-featured package manager. The target audience for this packager is not the big-time distribution developers, but a single user rolling his or her own at home (or in a small office). This utility is part of the Source Ruckus project.
dput-webdav is a "dput" upload method plugin with extended WebDAV support. It was written specifically with Artifactory and Bintray in mind. It tries to be compatible with the "http" plugin, but offers additional features: login credentials can include the password, "incoming" can be a full URL (optionally containing dynamic package metadata, and supporting HTTPS), and distributions can be mapped to repository names.
ivepkg is a package manager with a focus on homebuilt distributions like Linux From Scratch. Therefore, ivepkg has no repository or network abilities, but is specialized on installing tarballs to a system. Its key features are an easy-to-use database (sqlite3) and a sha1 checksum of every installed file. These make it possible to know which files have been altered (for example, by a malicious attack).
