-# You may edit it if you are careful; however, you may see cryptic errors if you
-# violate Teliva's assumptions.
-#
-# .tlv files are representations of Teliva programs. Teliva programs consist of
-# sequences of definitions. Each definition is a table of key/value pairs. Keys
-# and values are both strings.
-#
-# Lines in .tlv files always follow exactly one of the following forms:
-# - comment lines at the top of the file starting with '#' at column 0
-# - beginnings of definitions starting with '- ' at column 0, followed by a
-#   key/value pair
-# - key/value pairs consisting of '  ' at column 0, containing either a
-#   spaceless value on the same line, or a multi-line value
-# - multiline values indented by more than 2 spaces, starting with a '>'
-#
-# If these constraints are violated, Teliva may unceremoniously crash. Please
