Most OSes have SCSI pass-through interfaces that enable user space programs to send SCSI commands to a device and fetch the response. With SCSI to ATA Translation (SAT) many ATA disks now can process SCSI commands. Typically each utility in this package implements one SCSI command. See the draft standards at www.t10.org for SCSI command definitions plus SAT. ATA commands are defined in the draft standards at www.t13.org . For a mapping between supported SCSI and ATA commands and utility names in this package see the COVERAGE file.

The pkg_resources module provides an API for Python libraries to access their resource files, and for extensible applications and frameworks to automatically discover plugins. It also provides runtime support for using C extensions that are inside zipfile-format eggs, support for merging packages that have separately-distributed modules or subpackages, and APIs for managing Python's current "working set" of active packages.

This package contains the shared libraries needed by binaries that use autoopts for option processing. The package containing the header files and static libraries is libopts25-dev. The package containing the development tools is autogen.
