# Come forth all ye pilgrims to this monastary of learning.
# Bringeth your Manpages and the books of O'Reilly and hold 
# them up to the lord.  They contain truths that cannot be
# denied.  The road to wisdom is hard, but through the hills
# and valleys you will be not alone.  Persevere in your 
# studies, and know that some secrets are worth the toil.
