# sudo aptitude show binfmt-support
Package: binfmt-support
State: installed
Automatically installed: yes
Version: 1.2.18
Priority: optional
Section: admin
Maintainer: Colin Watson <cjwatson@debian.org>
Uncompressed Size: 168k
Depends: perl, lsb-base (>= 3.0-6)
Description: Support for extra binary formats
 The binfmt_misc kernel module, contained in versions 2.1.43 and later of the Linux kernel, allows system administrators to register
 interpreters for various binary formats based on a magic number or their file extension, and cause the appropriate interpreter to be
 invoked whenever a matching file is executed. Think of it as a more flexible version of the #! executable interpreter mechanism.

 This package provides an 'update-binfmts' script with which package maintainers can register interpreters to be used with this module
 without having to worry about writing their own init.d scripts, and which sysadmins can use for a slightly higher-level interface to this
 module.
