NAME

       dose-ceve - parse package metadata

SYNOPSIS

       dose-ceve [-h] [-v] [-e pkgspec] [-c pkgspec] [-r pkgspec] [--depth=n] [-t format] [-o filename] input-spec

DESCRIPTION

       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.

OPTIONS

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

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

       -e pkgspec
	   (Option Not Implemented Yet) Extract the transitive closure of packages connected (by conflict or dependency) to any of the packages
	   that satisfy pkgspec. Such a package specification is a list of packages (separated by a semicolon), where each package is specified as
	   follows: (name,version). This option can also be specified as --extract=pkgspec.

       -c pkgspec
	   Similar to the -c option, but only uses the dependency relation to make the transitive closure. This option can also be specified as
	   --cone=pkgspec.

       -r pkgspec
	   Similar to the -e and -c options, but uses the reverse dependency relation to make the transitive closure. This option can also be
	   specified as --rcone=pkgspec.

       --depth=n
	   In combination with the -e, -c or -r options, this specifies the maximum depth for the transitive closure.  =item -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 format. This option
	   can also be specified as --outtype=format.

       -o filename
	   Instead of stdout, send output to the file filename. This option can also be specified as --outfile=filename.  =item input-spec

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

	   cudf for cudf files =item *

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

	   debstdin for Debian package files read from standard input =item *

	   eclipse for Eclipse (p2) package files =item *

	   pgsql for PostgreSQL databasess =item *

	   sqlite for sqlite databases

       *   hdlist for RPM hdlists =item *

	   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)

       *   psql://user@db.mancoosi.org:723/packages (the database packages on host db.mancoosi.org on port 723, accessed as user user)
