//: You guessed right: the '000' prefix means you should start reading here.
//:
//: This project is setup to load all files with a numeric prefix. Just create
//: a new file and start hacking.
//:
//: The first few files (00*) are independent of what this program does, an
//: experimental skeleton that will hopefully make it both easier for others to
//: understand and more malleable, easier to rewrite and remould into radically
//: different shapes without breaking in subtle corner cases. The premise is
//: that understandability and rewrite-friendliness are related in a virtuous
//: cycle. Doing one well makes it easier to do the other.
//:
//: Lower down, this file contains a legal, bare-bones C++ program. It doesn't
//: do anything yet; subsequent files will contain :(...) directives to insert
//: lines into it. For example:
//:   :(after "more events")
//: This directive means: insert the following lines after a line in the
//: program containing the words "more events".
//:
//: A simple tool is included to 'tangle' all the files together in sequence
//: according to their directives into a single source file containing all the
//: code for the project, and then feed the source file to the compiler.
//: (It'll drop these comments starting with a '//:' prefix that only make
//: sense before tangling.)
//:
//: Directives free up the programmer to order code for others to read rather
//: than as forced by the computer or compiler. Each individual feature can be
//: organized in a self-contained 'layer' that adds code to many different data
//: structures and functions all over the program. The right decomposition into
//: layers will let each layer make sense in isolation.
//:
//:   "If I look at any small part of it, I can see what is going on -- I don't
//:   need to refer to other parts to understand what something is doing.
//:
//:   If I look at any large part in overview, I can see what is going on -- I
//:   don't need to know all the details to get it.
//:
//:   Every level of detail is as locally coherent and as well thought-out as
//:   any other level."

//:
//: Directives are powerful; they permit inserting or modifying any point in
//: the program. Using them tastefully requires mapping out specific lines as
//: waypoints for future layers to hook into. Often such waypoints will be in
//: comments, capitalized to hint that other layers rely on their presence.
//:
//: A single waypoint might have many different code fragments hooking into
//: it from all over the codebase. Use 'before' directives to insert
//: code at a location in order, top to bottom, and 'after' directives to
//: insert code in reverse order. By convention waypoints intended for insertion
//: before begin with 'End'. Notice below how the layers line up above the "End
//: Foo" waypoint.

//:   File 001          File 002                File 003
//:   ============      ===================     ===================
//:   // Foo
//:   ------------
//:              <----  :(before "End Foo")
//:                     ....
//:                     ...
//:   ------------

//:
//: Here's part of a layer in color: http://i.imgur.com/0eONnyX.png. Directives
//: are shaded dark.
//:
//: Layers do more than just shuffle code around. Their guarantee is that it
//: should be possible to stop loading after any file/layer, build and run the
//: program, and pass all tests for loaded features. (Relevant is
//: http://youtube.com/watch?v=c8N72t7aScY, a scene from "2001: A Space
//: Odyssey".) Use the included script called 'test_all_layers' to check the
//: guarantee if you make any changes.
//:
//: This 'subsetting guarantee' ensures that this directory contains a
//: cleaned-up narrative of the evolution of this codebase. Organizing
//: autobiographically allows a newcomer to rapidly orient himself, reading the
//: first few files to understand a simple gestalt of a program's core purpose
//: and features, and later gradually working his way through other features as
//: the need arises.
//:
//: Programmers shouldn't need to understand everything about a program to hack
//: on it. But they shouldn't be prevented from a thorough understanding of
//: each aspect either. The goal of layers is to reward curiosity.
