DESCRIPTION

       chdist is a rewrite of what used to be known as 'MultiDistroTools' (or mdt). Its use is to create 'APT trees' for several distributions,

       -d, --data-dir DIR
	   Choose data directory (default: $HOME/.chdist/).

       -a, --arch ARCH
	   Choose architecture (default: `dpkg --print-architecture`).

       --version
	   Display version information.

COMMANDS

       create DIST [URL RELEASE SECTIONS]
	   Prepare a new tree named DIST

       apt-get DIST <update|source|...>

       apt-rdepends DIST [...]

       src2bin DIST SRCPKG
	   List binary packages for SRCPKG in DIST

       bin2src DIST BINPKG
	   List source package for BINPKG in DIST

       compare-packages DIST1 DIST2 [DIST3, ...]
       compare-bin-packages DIST1 DIST2 [DIST3, ...]
	   List versions of packages in several DISTributions

       compare-versions DIST1 DIST2
       compare-bin-versions DIST1 DIST2
	   Same as compare-packages/compare-bin-packages, but also runs dpkg --compare-versions and display where the package is newer.

       compare-src-bin-packages DIST
	   Compare sources and binaries for DIST

       compare-src-bin-versions DIST
	   Same as compare-src-bin-packages, but also run dpkg --compare-versions and display where the package is newer
