TTDWYCYDE = Things To Do When You Change Your Dynamips Environment

'Environment Change' includes but not limited to:
- IOS change (including 'minor' change, say 12.4.10 to 12.4.12 for the
same feature set)
- dynamips version change (say from 2.6RC3 to 2.6RC4)
- kernel change (for Linux/UNIX), even changing a single kernel
perameter line is counted as 'environment change' ;)
- hardware change (minor effect, but it's worth checking your idlepc)

Changing file locations (i.e.: working directory, IOS locations,
dynamips execs, dynagen execs, etc.) *might* not affect anything. But
if you are unsure, feel free tore run the idlepc process again.

The moral of the story is: if you could afford the real router, then
buy one! :D
