* Adding new users AUTOMATED. * Update docs for the new, more simplified installation processes. * Remove dependency on any particular paths, etc. Copy "bin" into a place along your path and everything should "just work". * Add support for Mercurial (not tested). * blackbox_addadmin now adds keys to the keyring for you. * Unified #! lines to "#!/usr/bin/env bash" so it works better on FreeBSD. * BUGFIX: (BugId#1) blackbox_update_all_files.sh expects hg, fails for git. * BUGFIX: (BugId#2) blackbox_postdeploy.sh assumes certain directory layout. * BUGFIX: Temporary files aren't deleted. * NEW FILE: bin/blackbox_initialize: Automates enabling BB for a repo (creates directories, files, and updates .gitignore). * NEW FILE: bin/blackbox_removeadmin: Automates removing an admit. * NEW FILE: tools/confidence_test.sh: A battery of tests to verify operations. * NEW FILE: bin/Makefile: Automate package creation. * NEW FILE: bin/_stack_lib.sh: A library of shell routines from StackExchange.
