+# The "nj" ninja builder
+#
+# From any directory in a Git worktree, 'nj' will jump to the build
+# directory, build, and optionally install your project.
+#
+# It supports in-tree builds, a single out-of-tree build (in build/),
+# or multiple out-of-tree builds (in build/*/).
+#
+# Usage:
+# $ nj [<build>] [<targets>] # if using multiple out-of-tree builds.
+# $ nj [<targets>]           # if using an in-tree or single out-of-tree build
+#
+# By default, <build> defaults to "debug".
+#
+# Setup:
+#
+# You can create multiple out-of-tree builds, named whatever you like.
+# An example build called 'debug' would look like:
+#
+# - build/debug
+# - build/debug/extratargets (optional)
+# - build/debug/install (optional)
+#
+# If no targets are specified, nj defaults to 'all'.  It appends the contents
+# of the 'extratargets' file, if it exists, allowing you to build additional
+# targets that aren't enabled by default in your project's build system, such
+# as 'check'.
+#
+# Additionally, if 'install' exists, it runs 'ninja install'.  This can be
+# a directory which you've set as Meson/CMake's install prefix, or just a
+# blank file if you want it to install elsewhere.
+# _____________________________________________________________________
