.SH NAME
.PP
\f[B]deb2docker\f[R] - Build a Docker image with given Debian packages
.SH SYNOPSIS
.PP
\f[B]deb2docker\f[R] [-hB][-c CMD][-f FROM][-n NAME][-o DIR][-p
PRE_SCRIPT][-s POST_SCRIPT] \f[I]packages\f[R]
.SH DESCRIPTION
.PP
\f[B]deb2docker\f[R] is a simple script which takes as input a list of
Debian packages and generates automatically a Docker container including
these packages.
A set of \f[I]freedesktop.org\f[R] desktop launchers are also generated
based on the .desktop and icon files found in the packages.
In addition, a desktop launcher is created to start the container in a
Terminal.
.PP
This tool is suited for deploying applications as containers, as well as
for testing Debian packages in a sandbox.
