.SH NAME
backportpackage \- helper to test package backports
.SH SYNOPSIS
.TP
.B backportpackage \fR[\fIadditional options\fR]
\-\-upload <\fIupload target\fR>
.br
<\fIsource package name or .dsc URL/file\fR>
.PP
.B backportpackage \-h
.SH OPTIONS
.TP
.B \-d \fIDEST\fR, \-\-destination=\fIDEST\fR
Backport the package to the specified Ubuntu release. If this option
is unspecified, then \fBbackportpackage\fR defaults to the release on
which it is currently running.
.TP
.B \-s \fISOURCE\fR, \-\-source=\fISOURCE\fR
Backport the package from the specified Ubuntu release. If neither
this option nor \fB\-\-version\fR are specified, then
\fBbackportpackage\fR defaults to the current Ubuntu development
release.
.TP
.B \-S \fISUFFIX\fR, \-\-suffix=\fISUFFIX\fR
Add the specified suffix to the version number when
backporting. \fBbackportpackage\fR will always append
~\fIDESTINATION\fR1 to the original version number, and if
\fISUFFIX\fR is specified, it is appended to that, to get version
numbers of the form
\fIORIGINAL_VERSION\fR~\fIDESTINATION\fR1\fISUFFIX\fR. If the
backported package is being uploaded to a PPA, then \fISUFFIX\fR
defaults to \fB~ppa1\fR, otherwise the default is blank.
.TP
.B \-b, \-\-build
Build the package with the specified builder before uploading. Note
for \fBpbuilder\fR(8) users: This assumes the common configuration,
where the \fBDIST\fR environment is read by \fBpbuilderrc\fR(5) to
select the correct base image.
.TP
.B \-B \fIBUILDER\fR, \fB\-\-builder\fR=\fIBUILDER
Use the specified builder to build the package. Supported are
\fBpbuilder\fR(8), \fBpbuilder-dist\fR(1), and \fBsbuild\fR(1). This overrides
\fBUBUNTUTOOLS_BUILDER\fR. The default is \fBpbuilder\fR(8).
.TP
.B \-U, \-\-update
Update the build environment before attempting to build.
.TP
.B \-u \fIUPLOAD\fR, \-\-upload=\fIUPLOAD\fR
Upload to \fIUPLOAD\fR with \fBdput\fR(1) (after confirmation).
.TP
.B \-y, \-\-yes
Do not prompt before uploading to a PPA. For everyone's safety, this
option is ignored if \fIUPLOAD\fR is \fBubuntu\fR.
.TP
.B \-v \fIVERSION\fR, \-\-version=\fIVERSION\fR
If the \fB\-\-source\fR option is specified, then
\fBbackportpackage\fR verifies that the current version of \fIsource
package\fR in \fISOURCE\fR is the same as \fIVERSION\fR. Otherwise,
\fBbackportpackage\fR finds version \fIVERSION\fR of \fIsource
package\fR, regardless of the release in which it was published (or if
that version is still current). This option is ignored if a .dsc URL
or path is passed in instead of a source package name.
.TP
.B \-w \fIWORKDIR\fR, \-\-workdir=\fIWORKDIR\fR
If \fIWORKDIR\fR is specified, then all files are downloaded,
unpacked, built into, and otherwise manipulated in
\fIWORKDIR\fR. Otherwise, a temporary directory is created, which is
deleted before \fIbackportpackage\fR exits.
.TP
.B \-l \fIINSTANCE\fR, \-\-launchpad=\fIINSTANCE\fR
Use the specified instance of Launchpad (e.g. "staging"), instead of
the default of "production".
.TP
.B \-\-no\-conf\fR, \fB\-\-noconf
Do not read any configuration files.
This can only be used as the first option given on the command\-line.
.SH DESCRIPTION
\fBbackportpackage\fR fetches a package from one Ubuntu release or
from a specified .dsc path or URL and creates a no-change backport of
that package to a previous release, optionally doing a test build of
the package and/or uploading the resulting backport for testing.
.PP
Unless a working directory is specified, the backported package is
fetched and built in a temporary directory in \fB/tmp\fR, which is
removed once the script finishes running.
.PP
\fBbackportpackage\fR is only recommended for testing backports in a
PPA, not uploading backports to the Ubuntu archive.
