+# Intro
+
+The fundamental problem:
+
+```bash
+git submodule update --init soundscape
+cargo build --release
+install -pm755 target/release/tap /usr/local/bin/
+```
+
+You can't type this after every test.
+
+***
+
+## First Solution
+
+```bash
+#!/bin/sh
+git submodule update --init soundscape
+cargo build --release
+install -pm755 target/release/tap /usr/local/bin/
+```
+
+At this point, every test takes 10 minutes.
+
+## Second Solution
+
+```bash
+#!/bin/sh
+[ -f soundscape/.git ] || git submodule update --init soundscape
+[ -f target/release/tap ] || cargo build --release
+[ -f target/release/tap ] || \
+    install -pm755 target/release/tap /usr/local/bin/
+```

+- input, process, output.
+- automatic idempotence
+
+```bash
+INSTALL_DIR = /usr/local/bin
+
+soundscape/.git:
+    git submodule update --init soundscape
+
+/usr/local/bin/tap: target/release/tap
+	install -pm755 target/release/tap $(INSTALL_DIR)
+
+target/release/tap: src soundscape/.git
+	cargo build --release
+```
+
+***
+
+# Basic
+
+- *Gotcha*: directories
+- This, that, and these
+
+***
+
+## Repetition, Repetition, Repetition
+
+```make
+.PHONY: output
+output: release/index.html
+
+release/: backups.zip
+	mkdir $@
+
+release/index.html: index.html release/
+	cp  $< $@
+
+index.html: backups.zip
+	unzip $<
+```
+
+***
+
+# Variables
+
+- From your shell.
+- New variables.
+- Filenames as variables.
+- *Gotcha*: no shell variables, only make!
+
+## Equality
+
+- Variables with '=', never ':='.
+- *Gotcha*: one shell per line.
+- Variables as shell output.
+
+
+***
+
+
+# Phonies, and the Problems with Lies
+
+- clean (common)
+- check (excellent)
+
+***
+
+
+## Non-Compiling Checks
+
+- `make` -n
+- *Gotcha*: shell output variables.
+

+
+
+# The Fourth Sigil: `%`
+
+- Standard rules, e.g. ImageMagick, copying, et c.
+- *Gotcha*: intermediaries are deleted.
+
+***
+
+# Bling: make2graph
+
+- *Gotcha*: completely outdated.
+
+***
+
+# Inclusivity
+
+- `include dir/Makefile`
+- *Gotcha*: directory has not changed
+- `$(MAKEFILE_LIST)`
+
+
+# Special Commands
+
+- dir
+- `DIR = test -d $(dir $@) || mkdir $(dir $@)`
+- patsubst
+- Wildcards (or not?)

+# Maintanance
