+The source tree maps to the DNS namespace that we own. The purpose of this
+mapping is to keep things organized hierarchically in how they are deployed on
+the Internet. The main 'common' space is `com.simatime`, everything else should
+be related to the application.
 
-This isn't totally in place yet, but it's something to work toward.
+Development aspects should be localized to their sub-namespaces as much as
+possible. Only after sufficient iteration such that interfaces are solidified
+and functionality is well-established should some code be promoted up the
+namespace hierarchy.
 
-The main source directory is `lore`. Stuff in `aero` and `apex` should be small
-functions specific to the server/client.
+Boundaries and interfaces between namespaces should be small and
+well-defined. Likewise, the functionality and purpose of a particular namespace
+should be small and well-defined. Following the unix principle of "do one thing
+and do it well" is advised.
 
-The two special locations are `soar` and `bild`. The former is for images and
-other assets to be synced to digital ocean's object storage. The latter's
-contents are gitignore'd and can be deleted at any time because they will just
-be rebuilt later.
+Namespaces refer to conceptual boundaries. Implementations can be in any number
+of languages, indicated by the file extension. For example, we can have
+`com.example.api.hs` and `com.example.api.scm` in order to have an API client in
+both Haskell and Scheme. Building `com.example.api` should compile both pieces
+of code.

-To get a development shell, for example to work on ibb, you can do:
-
-    $ nix-shell -A pack.ibb
-    $ chip/make ibb

-The build system topology is defined in `./default.nix`, so follow the import
-paths there to see what's available for building and installing locally. For
-example, to build `ibb`: `nix-build -A pack.ibb`. Or, to build the main app
-server with all dependencies and configuration: `nix-build -A
-depo.nutin-madaj.system`. Omitting `.system` will also build a VM that you can
-run locally for testing.

+;; bild - a simple build tool
+;;
+;;; Commentary:
+;;
+;; Design constraints
+;;
+;; - only input is a namespace, no subcommands, no packages
+;; - no need to write specific build rules
+;;   - one rule for hs, one for rs, one for scm, and so on
+;; - no need to distinguish between exe and lib, just have a single output
+;; - never concerned with deployment/packaging - leave that to another tool (scp? tar?))
+;;
+;; Features
+;;
+;; - namespace maps to filesystem
+;;   - no need for `bild -l` for listing available targets. Use `ls` or `tree`
+;;   - you build namespaces, not files/modules/packages/etc
+;; - namespace maps to language modules
+;;   - build settings can be set in the file comments
+;; - pwd is always considered the the source directory, no `src` vs `doc` etc.
+;; - build methods automaticatly detected with file extensions
+;; - flags modify the way to interact with the build
+;;   - -s = jump into a shell and/or repl
+;;   - -p = turn on profiling
+;;   - -t = limit build by type
+;;   - -e = exclude some regex in the ns tree
+;;   - -o = optimize level
+;;
+;; Example Commands
+;;
+;;     bild [-rpt] <target..>
+;;
+;; The general scheme is to build the things described by the targets. A target
+;; is a namespace. You can list as many as you want, but you must list at least
+;; one. It could just be `.` for the current directory. Build outputs will go
+;; into the _bild directory in the root of the project.
+;;
+;;     bild biz.web
+;;
+;; Or `bild biz/web`. This shows building a file at ./biz/web.hs, this will
+;; translate to something like `ghc --make Biz.Web`.
+;;
+;;     bild -r <target>
+;;
+;; Starts a repl/shell for target.
+;;   - if target.hs, load ghci
+;;   - if target.scm, load scheme repl
+;;   - if target.clj, load a clojure repl
+;;   - if target.nix, load nix-shell
+;;   - and so on.
+;;
+;;     bild -p <target>
+;;
+;; build target with profiling (if available)
+;;
+;;     bild -t nix target
+;;
+;; only build target.nix, not target.hs and so on (in the case of multiple
+;; targets with the same name but different extension).
+;;
+;; Here is an example integration with GHC. Given the following command-line
+;; invocation to compile the namespace 'com.simatime.bild' which depends on
+;; 'com.simatime.lib':
+;;
+;;     ghc com/simatime/bild.hs -i com/simatime/lib.hs -o _bild/bild -v \
+;;         -main-is Com.Simatime.Bild.main
+;;
+;; The general template of which is:
+;;
+;;     ghc <source> -i <deps..> -o <target> -main-is <target>.main
+;;
+;; Some definitions:
+;;
+;; - <source> is some source file
+;; - <deps..> is the stack of dependencies
+;; - <target> is the target namespace, indicated by 'bild <target>'
+;;
+;; To fill out the build template, we can parse the file for known
+;; namespaces. The general recipe is:
+;;
+;; 1. Create a list of namespaces in my git repo. This can be cached, or I can
+;;    integrate with git somehow.
+;; 2. Read the <source> file corresponding to <target>
+;; 3. Look for 'import <namespace>', where <namespace> is a namespace in the
+;;    aforementioned cache.
+;; 4. If found, then save current build as a continuation and compile
+;;    <namespace>. Result gets put on the dependency stack
+;; 5. When finished, return to building <target>
+;;
+;; Once the build command template is filled out, we can create the nix expression.
+;;
+;; TODO
+;;
+;; Questions
+;;
+;; - how to import (third-party) dependencies?
+;;   1 just don't have them...? yeah right
+;;   2 the target.nix could be the build description for target.hs
+;;   3 just use a default.nix for the com.whatever
+;;   4 have a deps.nix file
+;;   5 list them in the file with other settings
+;; - how to handle multiple output formats?
+;;   - e.g. that ghcjs and ghc take the same input files...
+;;   - say you have a .md file, you want to bild it to pdf, html, and more. What do?
+;;   - i guess the nix file could return a set of drvs instead of a single drv
+;;   - the top of the file should
