NAME

       debcheckout - checkout the development repository of a Debian package

SYNOPSIS

       debcheckout [OPTIONS] PACKAGE [DESTDIR]
       debcheckout [OPTIONS] REPOSITORY_URL [DESTDIR]
       debcheckout --help

DESCRIPTION

       debcheckout retrieves the information about the Version Control System used to maintain a given Debian package (the PACKAGE argument), and
       then checks out the latest (potentially unreleased) version of the package from its repository.	By default the repository is checked out
       to the PACKAGE directory; this can be overridden by providing the DESTDIR argument.

       The information about where the repository is available is expected to be found in Vcs-* fields available in the source package record. For
       example, the vim package exposes such information with a field like Vcs-Hg:http://hg.debian.org/hg/pkg-vim/vim, you can see it by grepping
       through apt-cache showsrc vim.

       If more than one source package record containing Vcs-* fields is available, debcheckout will select the record with the highest version
       number.	Alternatively, a particular version may be selected from those available by specifying the package name as PACKAGE=VERSION.

       If you already know the URL of a given repository you can invoke debcheckout directly on it, but you will probably need to pass the
       appropriate -t flag. That is, some heuristics are in use to guess the repository type from the URL; if they fail, you might want to
       override the guessed type using -t.

       The currently supported version control systems are: Arch (arch), Bazaar (bzr), CVS (cvs), Darcs (darcs), Git (git), Mercurial (hg) and
       Subversion (svn).

OPTIONS

       GENERAL OPTIONS

       -a, --auth
	   Work in authenticated mode; this means that for known repositories (mainly those hosted on http://alioth.debian.org) URL rewriting is
	   attempted before checking out, to ensure that the repository can be committed to. For example, for Subversion repositories hosted on
	   alioth this means that svn+ssh://svn.debian.org/... will be used instead of svn://svn.debian.org/....

       -d, --details
	   Only print a list of detailed information about the package repository, without checking it out; the output format is a list of fields,
	   each field being a pair of TAB-separated field name and field value. The actual fields depend on the repository type. This action might
	   require a network connection to the remote repository.

	   Also see -p. This option and -p are mutually exclusive.

       -h, --help
	   Print a detailed help message and exit.

       -p, --print
	   Only print a summary about package repository information, without checking it out; the output format is TAB-separated with two fields:
	   repository type, repository URL. This action works offline, it only uses "static" information as known by APT's cache.

	   Also see -d. This option and -d are mutually exclusive.

       -P package, --package package
	   When checking out a repository URL, instead of trying to guess the package name from the URL, use this package name.

       -t TYPE, --type TYPE
	   Override the repository type (which defaults to some heuristics based on the URL or, in case of heuristic failure, the fallback "svn");
	   should be one of the currently supported repository types.

       -u USERNAME, --user USERNAME
	   Specify the login name to be used in authenticated mode (see -a). This option implies -a: you don't need to specify both.

       -f, --file
	   Specify that the named file should be extracted from the repository and placed in the destination directory. May be used more than once
	   to extract mutliple files.

       --source=never|auto|download-only|always
	   Some packages only place the debian directory in version control.  debcheckout can retrieve the remaining parts of the source using
	   apt-get source and move the files into the checkout.

	   never
	       Only use the repository.

	   auto (default)
	       If the repository only contains the debian directory, retrieve the source package, unpack it, and also place the .orig.tar.gz file
	       into the current directory. Else, do nothing.

	   download-only
	       Always retrieve the .orig.tar.gz file, but do not unpack it.

	   always
	       Always retrieve the .orig.tar.gz file, and if the repository only contains the debian directory, unpack it.

       VCS-SPECIFIC OPTIONS

       GIT-SPECIFIC OPTIONS

       --git-track BRANCHES
	   Specify a list of remote branches which will be set up for tracking (as in gitbranch--track, see git-branch(1)) after the remote Git
	   repository has been cloned. The list should be given as a space-separated list of branch names.

	   As a shorthand, the string "*" can be given to require tracking of all remote branches.

CONFIGURATION VARIABLES

       The two configuration files /etc/devscripts.conf and ~/.devscripts are sourced by a shell in that order to set configuration variables.
       Command line options can be used to override configuration file settings. Environment variable settings are ignored for this purpose. The
       currently recognised variables are:

       DEBCHECKOUT_AUTH_URLS
	   This variable should be a space separated list of Perl regular expressions and replacement texts, which must come in pairs: REGEXP TEXT
	   REGEXP TEXT ... and so on. Each pair denotes a substitution which is applied to repository URLs if other built-in means of building
	   URLs for authenticated mode (see -a) have failed.

	   References to matching substrings in the replacement texts are allowed as usual in Perl by the means of $1, $2, ... and so on.

	   This setting can be used to enable authenticated mode for most repositories out there.  Note that the Debian repositories on
	   alioth.debian.org ($vcs.debian.org) are implicitly defined.

	   Here is a sample snippet suitable for the configuration files:

	    DEBCHECKOUT_AUTH_URLS='
	     ^w+://(svn.example.com)/(.*)	svn+ssh://$1/srv/svn/$2
	     ^w+://(git.example.com)/(.*)	git+ssh://$1/home/git/$2
	    '

	   Note that whitespace is not allowed in either regexps or replacement texts. Also, given that configuration files are sourced by a
	   shell, you probably want to use single quotes around the value of this variable.

       DEBCHECKOUT_SOURCE
	   This variable determines under what scenarios the associated orig.tar.gz for a package will be downloaded.  See the --source option for
	   a description of the values.
