Disregard the lin which starts in "%" for erb files.

[vStone]

care to add an example of a template where this is used?

[tommodore]

for example a sudo template:

...
# User privilege specification
%admin <%= @hostname %>=(ALL) ALL
root    ALL=(ALL:ALL) ALL
ROOTS   <%= @hostname %>=(ALL:ALL) ALL

# Allow members of group sudo to execute any command
%sudo  <%= @hostname %>=(ALL:ALL) ALL
...
