It's time to start preparing for a version of redo that doesn't work unless we build it first (because it will rely on C modules, and eventually be rewritten in C altogether). To get rolling, remove the old-style symlinks to the main programs, and rename those programs from redo-*.py to redo/cmd_*.py. We'll also move all library functions into the redo/ dir, which is a more python-style naming convention. Previously, install.do was generating wrappers for installing in /usr/bin, which extend sys.path and then import+run the right file. This made "installed" redo work quite differently from running redo inside its source tree. Instead, let's always generate the wrappers in bin/, and not make anything executable except those wrappers. Since we're generating wrappers anyway, let's actually auto-detect the right version of python for the running system; distros can't seem to agree on what to call their python2 binaries (sigh). We'll fill in the right #! shebang lines. Since we're doing that, we can stop using /usr/bin/env, which will a) make things slightly faster, and b) let us use "python -S", which tells python not to load a bunch of extra crap we're not using, thus improving startup times. Annoyingly, we now have to build redo using minimal/do, then run the tests using bin/redo. To make this less annoying, we add a toplevel ./do script that knows the right steps, and a Makefile (whee!) for people who are used to typing 'make' and 'make test' and 'make clean'.

redo - a recursive build system
Smaller, easier, more powerful, and more reliable than make.
This is an implementation of Daniel J. Bernstein's redo build system. He never released his version, so other people have implemented different variants based on his published specification.
This version, sometimes called apenwarr/redo, is probably the most advanced one, including support for parallel builds, improved logging, and helpful debugging features.
To build and test redo, run ./do -j10 test. To install it, run
DESTDIR=/tmp/testinstall PREFIX=/usr/local ./do -j10 install.
