+# ABOUT
+# - In this Makefile, 'building a file' means:
+# 	- if the file has a '.html' extension: run the html preprocessor on the file and place the output in the output directory
+# 	- elif the file has a '.sass' or '.scss' extension: run the sass compiler on the file and place the output in the output directory
+# 	- else: copy the file to the output directory
+# - Folder structure from source directories will be preserved in the output directory
+# - Abbreviations:
+#   - FLS: files
+#   - DIR: directory
+#   - SRC: source
+#   - LANG: language
+#   - PP: preprocessor
+#   - DEP: dependency
