 #define TAGS_H
 
 /*
-	tags are stored in a big string, separated by semicolons (;)
-	tags can have namespaces, which should come before the tag
-	and be followed by a colon (:)
-	should a namespace store more than one tag, the following
-	tags will be separated by a comma (,)
-	spaces are only allowed inside tags or namespaces, as part
-	of themselves
-	semicolons, colons, and commas are not allowed inside tags
-	or namespaces
-	example: "person:ted kaczynsky;mood:serious;meta:jpg"
+	tags are stored in a big table (or their hashes are) ordered
+	by alphabetical order
+	tags can have namespaces which are a special tag that starts
+	with a ':'
+	all tags in a namespace are located between two occurrences
+	of the namespace within the list,
+		e.g [":people", "sam hyde", "hitler", ":people"]
+	maybe namespaces use another hashing function to prevent
+	collisions because of the lack of space because of the ':'
