I don't understand this. Cabal doesn't have any distro-specific code. > And besides, this ability has nothing to do with cabal's configuration > management capabilities, simply its metadata format. I don't understand this either. You imply you like Cabal's metadata, which says "I depend on network version 1", right? But you don't like Cabal's configuration management?

OK, so here's an encap package for DBI: http://encap.org/search/encapinfo.fcgi?collection=cites&archive=DBI-1.21-encap-sparc-solaris8.tar.gz ftp://ftp.encap.org/pub/encap/pkgs/cites/DBI-1.21-encap-sparc-solaris8.tar.gz This tarball contains an encapinfo file that says encap 2.1 # libencap-2.2.1 platform sparc-solaris8 date Mon Mar 11 19:38:02 CST 2002 contact "Mark D. Roth" <[EMAIL PROTECTED]> prereq pkgspec >= perl-5.6.1 So this is not a package manager for autoconf-style packages, it is a package manager for encap packages. Mark has had to download DBI, an autoconf-style package, examine its source code, determine that perl >= 5.6.1 is necessary in order to use it, and construct this encap package of DBI. The point of Cabal's design is that we don't want to have to have a Mark going round making encapinfo files; they come with the package. In a sense, writing a Cabal package is like writing an encap package directly, rather than first writing an autoconf-style package and then encapifying it.
