+# Compiling
+
+This script seems to handle most cases I care about:
+
+- a freshly cloned copy of the repository,
+- a repository where compilation has already happened,
+- a repository where I want to change the `configure` flags…
+
+``` bash
+#!/bin/bash
+
+set -eux
+
+MAKE="make -j$(nproc --all)"
+CONFIGURE_FLAGS="--with-xwidgets --with-cairo"
+
+if ! test -f Makefile
+then
+	${MAKE} configure
+fi
+
+check-config ()
+{
+    if ! test -f src/config.h
+    then
+        return 1
+    fi
+
+    local pattern='#define EMACS_CONFIG_OPTIONS "'${CONFIGURE_FLAGS}'"'
+    grep "${pattern}" src/config.h
+}
+
+if ! check-config
+then
+    ./configure ${CONFIGURE_FLAGS}
+fi
+
+if ! ${MAKE}
+then
+    ${MAKE} bootstrap
+fi
+```
