# .tlv file generated by https://github.com/akkartik/teliva
|
|
# 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
|
|
# report bugs at http://akkartik.name/contact
