Line 11

* 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.
