This is magicfilter 2.3 It's somewhat different from magicfilter 1.2: * the printer definition file format has changed; it is now a simple m4 macro file that passes define()'s in to magicfilter. * the code uses libmagic (either the one in recent versions of file(1) or a homemade clone of it in the copy of file that's included in the sources) to do pattern matching instead of hand-identifying file types. * system() is no longer used to execute filters and pipes; they are now directly execvp'ed to cut down on the number of processes magicfilter launches. This means that environment variables are no longer substituted, except for the special case of single arguments named $FILE, which, if they are arguments to fpipe and ffilters, will be replaced with the name of the scratchfile created for the pipe. If this is a major problem, pester me and I'll think about putting system() back in. * all new processes are children of magicfilter, instead of some being punted off into their own little groups. * reject doesn't do mail notifications yet. Building magicfilter magicfilter 2.3 doesn't use gnu autoconf any more, because gnu autoconf requires gnu m4 and I don't have that on Mastodon. Instead, I've written my own little replacement called configure.sh, which works somewhat the same as the gnu configure script: I configure magicfilter via: CC="cc -baout -m386" CFLAGS="-O2" ./configure.sh --prefix=/usr ./configure.sh --help gives a listing of the options it currently accepts; most are similar to the gnu autoconf ones, except --path, which gives configure a path so it will look for programs in places other than the default /bin:/usr/bin:/usr/local/bin path. Copyrights libfile is made from the file(1) program, and carries the same BSD-style copyright. magicfilter itself ended up being completely rewritten, and now carries a BSD-style copyright. The manual pages were written by hpa, and thus carry the same copyright -- the GNU GPL -- as magicfilter 1.2 does. The filters were written by hpa, et alii, then trimmed fairly drastically for magicfilter 2. They are public domain. -david parsons (orc@pell.chi.il.us)
