# These examples are not perfect coding style because I took a real

# piece of code and tried to strip away anything that didn't make the error

# message go away.

# The interesting part of the 'truss' is:

# A sysadmin's life is a sorry one.  The only advantage he has over Emergency

# Room doctors is that malpractice suits are rare.  On the other hand, ER

# doctors never have to deal with patients installing new versions of their

# own innards!   -Michael O'Brien
