-
-midipix is a development environment that lets you create programs
-for Windows using the standard C and POSIX APIs. No compromises made,
-no shortcuts taken.
-
-If you are interested in cross-platform programming that reclaims
-the notion of write once, compile everywhere; if you believe that the
-'standard' in the C Standard Library should not be a null signifier;
-and if you like cooking your code without #ifdef hell and low-level
-minutiae, then this page is for you.
-
-midipix makes cross-platform programming better, simpler and faster,
-specifically by bringing a modern, conforming C Runtime Library to the
-Windows platform. While the idea itself is not new, the approach taken
-in midipix to code portability is radically different from that found
-in other projects.

-## 2. Building a midipix distribution
-
-A Midipix distribution consists of the following:
-* the native Midipix toolchain, consisting of perk, gcc, its dependencies,
- and binutils,
-* musl, a lightweight, fast, simple, and free libc&lbrack;[1](https://www.musl-libc.org/faq.html)&rbrack; used by Midipix,
-* 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
-* 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.
-
-Install the build-time dependencies listed in section [2.1](#21-build-time-dependencies),
-clone this repository, and run the following command line:
-
-```shell
-./build.sh -a nt64 -b release -D zipdist -P -v
-```
-
-By default, the build will take place within ``${HOME}/midipix/nt64/release``
-and package archive files and/or Git repositores will be downloaded into
-``${HOME}/midipix/dlcache``. Consult sections [3.1](#31-fault-tolerant--highly-optimised-3d-laser-show-equipped-usage-screen), [4](#4-build-variables), and [4.1](#42-package-variables)
-for the list of available build variables and how to override them.
-Parallelisation is enabled by the above command line for both packages that can
-be built independently of each other and ``make(1)`` via ``-j``, limited to the
-amount of logical processors on the build host divided by two (2).

+## 1. What is midipix, and how is it different?
+
+midipix is a development environment that lets you create programs
+for Windows using the standard C and POSIX APIs. No compromises made,
+no shortcuts taken.
+
+If you are interested in cross-platform programming that reclaims
+the notion of write once, compile everywhere; if you believe that the
+'standard' in the C Standard Library should not be a null signifier;
+and if you like cooking your code without #ifdef hell and low-level
+minutiae, then this page is for you.
+
+midipix makes cross-platform programming better, simpler and faster,
+specifically by bringing a modern, conforming C Runtime Library to the
+Windows platform. While the idea itself is not new, the approach taken
+in midipix to code portability is radically different from that found
+in other projects.

+## 2. Building a midipix distribution
+
+A Midipix distribution consists of the following:
+* the native Midipix toolchain, consisting of perk, gcc, its dependencies,
+ and binutils,
+* musl, a lightweight, fast, simple, and free libc&lbrack;[1](https://www.musl-libc.org/faq.html)&rbrack; used by Midipix,
+* 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
+* 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.
+
+Install the build-time dependencies listed in section [2.1](#21-build-time-dependencies),
+clone this repository, and run the following command line:
+
+```shell
+./build.sh -a nt64 -b release -D zipdist -P -v
+```
+
+By default, the build will take place within ``${HOME}/midipix/nt64/release``
+and package archive files and/or Git repositores will be downloaded into
+``${HOME}/midipix/dlcache``. Consult sections [3.1](#31-fault-tolerant--highly-optimised-3d-laser-show-equipped-usage-screen), [4](#4-build-variables), and [4.1](#42-package-variables)
+for the list of available build variables and how to override them.
+Parallelisation is enabled by the above command line for both packages that can
+be built independently of each other and ``make(1)`` via ``-j``, limited to the
+amount of logical processors on the build host divided by two (2).

+If a package build shell environment is desired for a package that has either not been
+built at all or built successfully, ``pkgshell.sh`` will attempt to rebuild the package
+at build steps up until, by default, ``build``, and then forcibly abort the build and
+write ``${BUILD_WORKDIR}/${PKG_NAME}.dump`` as above prior to entering the shell.
+

+## 4.1. Build steps
+
+Package builds are divided up into consecutively executed build steps until
+completion or aborted on failure unless relaxed mode is enabled by passing
+``-R``.
+
+Each build step corresponds to a function in the corresponding ``subr/pkg_*.subr``
+script and may be overriden entirely by a function named ``pkg_<package name>_<build step>()``
+or composed in terms of prior and/or subsequent execution by a function named
+``pkg_<package name>_<build step>_pre()`` and/or ``pkg_<package name>_<build step>_post()``,
+respectively, in the package's ``vars`` file. If a function named ``pkg_<package name>_all()``
+exists, it will override all build steps.
+
+Build step status is tracked on a per-package basis by state files beneath
+``${BUILD_WORKDIR}`` following the format ``.<package name>.<build step>``;
+package build completion corresponds to the pseudo-build step ``finish``.

+The following variables are package-specific and receive their value from either
+top-level defaults defined in ``midipix.env``, build group-specific defaults
+from the build group the package pertains to and defined in its corresponding
+file beneath ``groups/``, or package-specific overrides defined either in the

+Additionally, overrides may be specified on a per-build basis on the command-
+line after the last argument, with each variable prefixed w/ ``PKG_``, e.g.:
+``./build.sh [ ... ] PKG_ZSH_CC="/usr/bin/clang"``.
