  * Record a history of an mg session for temporal debugging.
  * Sometimes pressing a key will set the scene for a bug only visible 
  * dozens of keystrokes later. gdb has its limitations in this scenario.
+ *
+ * Note this file is not compiled into mg by default, you will need to
+ * amend the 'Makefile' for that to happen. Because of this, the code
+ * is subjet to bit-rot. However, I know myself and others have 
+ * written similar functionally often enough, that recording the below 
+ * in a code repository could aid the developement efforts of mg, even
+ * if it requires a bit of effort to get working. The current code is
+ * written in the spirit of debugging (quickly and perhaps not ideal,
+ * but it does what is required well enough). Should debugging become
+ * more formalised within mg, then I would expect that to change.
