Booleano is an interpreter of Boolean expressions; a library to define and run filters available as text (e.g. in a natural language) or in Python code. In order to handle text-based filters, Booleano ships with a fully-featured parser whose grammar is adaptive: Its properties can be overridden using simple configuration directives. On the other hand, the library exposes a Pythonic API for filters written in pure Python. These filters are particularly useful to build reusable conditions from objects provided by a third party library.
Vbackup is a modular backup utility that can be used to perform full or incremental system backups. It consists of a set of scripts that can be used to create backups using tar and xfsdump. It can also make backups of PostgreSQL, MySQL, and LDAP databases, keep a copy of the boot record, the partition table, or the LVM configuration, encrypt archives using x509 certificates, and back up the Debian package list and the RPM database. It can store the backups in a local or remote directory using either NFS or SCP. It is modular, and can be extended to perform other functions as well.
