For most stuff, you can simply cd into /usr/src/usr.bin/programname, or /usr/src/lib/libname, and run "make obj && make depend && make && make install". If you rebuild a library, though, it's up to you to make sure that you also rebuild any statically-linked programs using that library. There may also be issues where buiding one program may require another program to be updated (the texinfo stuff, for example, or a new copy of sed or make). The reason there's a "make world" is to ensure that all these dependencies are taken care of. -- Dan Nelson dnelson@allantgroup.com
