+# Constants
+
+Often you want to be able to use aliases for values inside your **EntityDef** files.
+
+For that, you can have a name/value pair mapping inside a text file named `scripts/constants.txt`.
+
+```
+// some comments here
+WEAPON_NONE	 0
+WEAPON_CROWBAR 1
+WEAPON_GLOCK 2
+[...]
+DEFAULT_NAME "Max"
+```
+
+And then you use the identifers in place of those constants. Similar to environment variables in the **UNIX** shell.
+
+```
+entityDef weapon_glock {
+	"spawnclass" "NSItem"
+	"inv_item" "$WEAPON_GLOCK"
+	[...]
+}
+```
