+                  Obtaining and installing a Midipix distribution
+                   Last update: Sun, 24 Apr 2016 09:42:40 +0000
+
+A Midipix distribution consists of the following:
+a) the native Midipix toolchain, consisting of perk, gcc, its dependencies,
+   and binutils,
+b) musl, a lightweight, fast, simple, and free libc[1] used by Midipix,
+c) the Midipix runtime components that bridge the gap between the libc and the
+   executive subsystems of all Windows NT-derived Windows OS starting with and
+   including Windows XP, and
+d) a steadily increasing number of 3rd party open source packages, as expected in
+   any modern POSIX-compliant *nix environment, including GNU coreutils, shells,
+   libraries such as ncurses, libressl, as well as Perl and Python.
+
+Compressed Midipix distribution tarballs and, separately, source tarballs are,
+at present, produced every four (4) hours UTC after each successful build and
+subsequently signed. This process is fully automated by a portable Bourne shell
+script; all of the above mentioned components are cross-compiled.
+
+Thus, the most hassle-free way to get started with Midipix is to simply download
+the most recent distribution tarball and follow the instructions below. It is,
+however, recommended to anyone intending to use Midipix as a development platform
+to familiarise themselves with the build process. Other reasons to prefer building
+a Midipix distribution yourself include integrating new 3rd party software or local
+runtime component patches. At present, a full build from scratch takes about 30
+(thirty) minutes to finish on an 8-core host with eight simultaneous make jobs,
+minus the generation of the tarballs. The build script can be obtained from the
+following GitHub repository: <https://github.com/lalbornoz/midipix_build>.
+
+If you obtained a Midipix distribution tarball, extract it into a directory and
+drive of your choice, henceforth referred to as target directory; the drive can
+be a network drive. Do _not_ use anything but a true UNIX environment tar(1), as
+e.g. WinRAR or WinZip handle extracting hard links incorrectly.
+If you built Midipix yourself, the target directory is equivalent to the ${PREFIX}
+configured in build.vars, which defaults to ${HOME}/midipix.
+
+At present, providing an interactive Midipix environment still requires the Cygwin
+terminal emulator Mintty and a shell; this does not include pseudoterminals, which
+are entirely handled by Midipix. Both can be installed via the 64-bit Cygwin setup
+program at <https://www.cygwin.com/setup-x86_64.exe>.
+
+Once installed, launching a Midipix shell is accomplished by the `midipix.sh' shell
+script provided in the target directory from within a Cygwin shell prompt in Mintty
+and the target directory. This may either simply be done manually each time, or
+automated by a shortcut. As shortcuts cannot be distributed, it can be created by
+either:
+a) Opening (executing) the VBScript script in the target directory from within the
+   latter cscript.exe, providing the fully qualified pathname to Mintty, if it differs
+   from the default value of C:\cygwin64\bin\mintty.exe or
+b) manually creating a shortcut to Mintty with `Start in:' set to the target directory
+   and the following command line:
+   [ ... ]\mintty.exe -i /Cygwin-Terminal.ico -e sh midipix.sh, or

+                   Last update: Tue, 26 Apr 2016 10:16:16 +0000
+
+The following build status codes are defined:
+C -- Complete build w/ at least the default configuration,
+B -- Broken, e.g. doesn't work at all or only minimally,
+I -- Integrated (e.g. linked against) with other packages,
+E -- Extensively tested and confirmed to work by multiple sources, possibly via a testsuite,
+P -- Patches needed to build that haven't been committed upstream yet, and
+U -- Update to latest stable version or HEAD pending.

+
+midipix alpha release: the final stretch
+========================================
+
+my.own.tasks@midipix.org
+------------------------
+
+* ofd tables: additional bucket allocation as needed.
+* `ls -R //c`: check for the cause of individual failures.
+  (might be related to the above ofd bucket allocation).
+* integrate clone and the initial ldso implementation.
+* integrate the signal queue, check signal implementation for
+  semantic completion, especially in the context of multi-threaded
+  applications.
+* implement /dev/random and /dev/urandom, as well as other virtual
+  folders needed by core applications.
+* implement the scheduler functions.
+* implement (possibly as stubs) missing system calls, fix existing
+  system calls as needed by the core applications.
+* toolchain: provided the few interfaces missing for C++ support.
+* porting of mintty.
+
+
+porting and other release-related tasks
+---------------------------------------
+
+* testing of ncurses.
+* testing of bash and dash when built with ncurses.
+* testing of all of the coreutils, seeing which ones fail due to
+  a missing virtual file or folder, which ones fail due to a missing
+  system call (crash), and which ones fail due to an incomplete or
+  incorrect system call.
+* porting of gdb.
