       dose-ceve - parse package metadata


       dose-ceve [-h] [-v] [-c pkgspec] [-r pkgspec] [--depth=n] [-T format] [-G graph type] [-o
       filename] input-spec


       Dose-ceve is a generalized metadata parser. It reads package specifications, extracts
       package metadata from them, performs some manipulations, and outputs the package metadata
       in one of several formats.


       -h  This option displays the help message. Can also be specified as --help.

       -v  Be verbose. This option can be repeated for more verbosity.

       -c pkgspec
           The match of an atomic dependency (a package name p possibly together with a version
           constraint c) is the set of all packages in the repository with name p, and a version
           that satisfies the constraint c.  The dependency cone of a package p is the set of all
           matches of all atomic dependencies of p, together with their respective dependency
           cones.  The package specification pkgspec is a list of packages (separated by a
           semicolon), where each package is specified as follows: (name,version).

           This option extracts the union of the dependency cones of all packages selected by
           pkgspec. This option can also be specified as --cone=pkgspec.

       -r pkgspec
           Using the same syntax as in -c, this option use the reverse dependency relation to
           make the transitive closure. This option can also be specified as --rcone=pkgspec.

       --depth n
           In combination with the -c or -r options, this specifies the maximum depth for the
           transitive closure.

       -T format
           Specifies the output format to use. Possible values are dot for a graph output in
           Dot/GraphViz format, cnf for an output in CNF format, dimacs for an output in the
           DIMACS format for CNF formulae, and cudf for a pretty-print output in an RFC 822-like

       -t input-spec
           Select the input type.

       --request installation-request
           Specifies an installation request of the form "install: vpkglist" or "remove:
           vpkglist" or "upgrade: vpkglist" where vpkglist is a list of (real) packages possibly
           associated with a constraint. Ex.: bash (< 2.0), exim (= 3.1-debian1). This option can
           be repeated to specify install, remove and upgrade actions.


       --request "install: bash (< 2.0), exim (= 3.1-debian1)" --request "upgrade: apt-cudf"
       -G graph type
           Specifies the graph type format to compute. This option must be used together with the
           option -T dot|gml|grml. Possible values are:

       .   syn for the syntactic graph where disjunctions nodes and conflicts are explicitly
           added to the graph.

       .   pkg for the package graph where all dependencies are threated uniformely and conflicts
           are not added to the graph.

       .   strong the strong dependency graph. A package p strong depends on q iff p cannot be
           installed if q is not installed.

       .   conj the conjunctive graph where only conjunctive dependencies are considered.

       -o filename
           Instead of stdout, send output to the file filename.

           This is a URL specifying both the input format and the file to get the input from.
           Possible schemes are:

       .   cudf for cudf files

       .   deb for Debian package files (possibly compressed with gzip(1) or bzip2(1), depending
           on compile-time options for dose3)

       .   debstdin for Debian package files read from standard input

       .   edsp for apt-get External Dependency Solver Protocol

       .   eclipse for Eclipse (p2) package files

       .   hdlist for RPM hdlists

       .   synth for urpmi synthesis hdlists

           Some examples of URLs:

       .   deb://Packages.gz (the Debian file packages.gz in the current directory)

       .   cudf:///home/examples/cudf/test.cudf (the CUDF file /home/examples/cudf/test.cudf)

       Multi-arch annotations are handled by dose-ceve. Packages whose's architecture is neither
       the native architecture nor in the list of foreign architectures (see below) are ignored.

               Specify the native architecture. The default behavior is to deduce the native
               architecture from the first package stanza in the input that has an architecture
               different from all.

       --deb-foreign-archs=name [,name] ...
               Specify a comma-separated list of foreign architectures. The default is an empty
               list of foreign architectures.

               By default all essential package are considered as a dependency of all packages in
               the universe. This option allows the user to ignore essential packages.
