Get rid of plumbing at the command line level. It is confusing to users, and command line arguments, exec calls and I/O streams are not efficient and reasonably typed mechanisms for the kind of operations done in plumbing. Instead using a good extensible portable scripting language (I consider Lua quite suitable in that regard, but it is conceivable that something with a native list type supporting easy sorts, merges and selections could be more efficient) and implementing plumbing in that or in C would have been preferable for creating the porcelain. That would keep plumbing out of the hair of users and make it easier to cobble together extensions and variations with non-trivial internal dataflow. Shell scripts have also proven to be a constant hassle with regard to portability and bugs (like underquoting). -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
