+# Builds an i3/i3status configuration file by merging
+# multiple defined configurations in an orderly manner.
+#
+# The files you wish to include MUST exist under ~/.config/i3(status)/layers.
+# The files MUST start with one of the defined "PATTERNS" below. However, they
+# WILL NOT be read unless explicitly mentioned in a .layer file located in the
+# same directory.
+#
+# Two .layer files are read during execution:
+# - default.layer
+# - $HOSTNAME.layer: This file doesn't have to exist, but will allow you to
+#   load a special set of files depending on the hostname of the machine which
+#   executes this script.
+#
+# The contents of the .layer files are read first, and then sorted.
