+#+BEGIN_QUOTE
+Code wrapped in =eval-after-load= will be executed only once, so it is typically used to perform
+one-time setup such as setting default global values and behaviour. An example might be setting
+up a default keymap for a particular mode. In =eval-after-load= code, there's no notion of the 
+"current buffer".
+
+Mode hooks exectue once for every buffer in which the mode is enabled, so they're used for per-buffer
+configuration. Mode hooks are therefore run later than =eval-after-load= code; this lets them take 
+actions baed upon such information as whether other modes are enabled in the current buffer.
